Danelaw Pitched Roofing
The Isle of Luing is one of the Slate Islands in the Inner Hebrides, in the west of Argyll in Scotland. Its charm lies in its natural beauty and unspoilt peaceful scenery looking out to the Inner Seas but is very exposed to the elements. Being coastal and located in BRE’s Wind Zone 4, properties need to be built with robustness and durability in mind.
The Danelaw SwiftRidg® Roll Top Ridge and Hip System, a new and innovative GRP product from Hambleside Danelaw, has been BRE tested to resist wind speeds exceeding 110mph. Comprising completely of corrosion resistant components and a unique concealed omega shaped fixing bracket to avoid any penetrations through the system, the SwiftRidg® was installed along all the ridge and hip lines.
An attractive and viable alternative to the traditional lead roll top ridge and hips, SwiftRidg® was installed on two properties along with Samaca Prime Slates on roofs covering an area of approximately 240m2; a perfect opportunity to showcase the neat and clean lines of the system.
Roofing contractors Kevin Mackie and Kieran Rowan admitted they were sceptical at first, as it is the first complete system of its kind, but with Paul Lambert (Hambleside Danelaw’s Field Technical Support) on hand, in addition to clear installation guidance they were impressed with the speed and ease of installation.
Kevin and Kieran had been contracted by Chris Parr Joinery and Building; and once the roof was complete, Chris Parr stated that “It looked great!”. The photos capture the beauty of the location, and the finish of the roof is clean, tidy and unobtrusive.
The SwiftRidg® is patent pending (Patent Application No. 2308115.1) and comes with a 20-year guarantee. Hambleside Danelaw also manufacture the SwiftRidg®+, which offers a ventilated option for ridge where required.
Express Lofts recently refurbished a residential property roof in Maidstone; re-tiling hip to gable, with a full width rear dormer.
When planning the installation, company director Dean Morris chose the unique Danelaw InVerg® interlocking dry verge system for plain double lap tiles. InVerg® has a patented design, which offers improved weather and wind resistance without reliance on mortar (GB Patent No: 2586153).
“I thought it was great…left a quality finish”, Dean said, “the ridge cap fits perfect”. Express Lofts purchased the InVerg® system from one of Hambleside Danelaw’s online stockists, Roofing Superstore. Ryan Holdford, Category Manager for Roofing stated “We’ve been stocking Hambleside Danelaw products for close to 15 years now which is a testament to the quality of their products and the high level of service they provide. They have been an ever-present figure on Roofing Superstore since we were founded providing high quality roofing solutions to both Tradesman and DIYers and contribute massively to the industry”.
So impressed was Dean, Express Lofts will now be offering the InVerg® as an option to all future customers, a great endorsement!

P.A. Leaford Traditional Roofing Tiler and Slater has recently completed two refurb/new build roofing projects in Cambridgeshire using Hambleside Danelaw’s CON6+ Dry Fix Ridge and Hip System purchased from Watts Roofing’s in Cambridge.
P.A. Leaford is a father and son roofing company built on the pride of workmanship with 25 years of experience. Based in Soham, Cambridgeshire, Wade Leaford joined 11 years ago; working alongside his dad, Paul Leaford. Their projects range from new builds to refurbishment, the duo have with decades of history attached to them.
Paul said:
“We bumped into Hambleside Danelaw on a site when the materials were provided by the main contractor. Since then, the CON6+ roll out ridge kit has been our number one choice, we recommend to our customers. We find the quality of the product and the materials used are far superior to other kits, giving us confidence on every install.’’
As previously mentioned, P.A. Leaford purchased Hambleside Danelaw’s CON6+ Dry Fix Ridge and Hip System from Watts Roofing Supplies in Cambridge. Watts Roofing Supplies was founded in 2010, located in Hertfordshire and Cambridgeshire. Watts Roofing believe in “building close customer relationships based on great customer service, supplying both Pitched and Flat Roofing products, insulation, cladding and commercial sheeting,
We have had an excellent relationship with Hambleside Danelaw for many years now, and have championed their products based on quality, and the fact they are always innovating and looking to expand their roofing solutions for our customers.”
Dan Spurling, Branch Manager at the Cambridge branch said:
”P. A. Leaford are a relatively new, but valued customer, of Watts Roofing in Cambridge; buying a range of primarily pitched roofing products.”

BS 5250 explains how underlays can help with roofing ventilation.
Hambleside Danelaw’s LR180 was selected for this project due to its high durability and heavier, premium weight. DMG Services Group Ltd got the underlay from One Stop Roofing Supplies, a stockist of Hambleside Danelaw products.
Darren McGhee, Managing Director of DMG Services Group Ltd, said “When pulling it across the open rafters, from right to left, its resistance to wind loads is second to none,” describing them as “a joy for roofers”.
East Kilbride, a town outside of Glasgow, falls within Wind Zone 3, meaning a range of our underlays would have been suitable for the housing development.
Hambleside Danelaw Underlays
Danelaw offers a variety of tile and slate underlays, with some having an option for a tape-to-tape system to remove the need for restraining batons at the lap line. Our range features 5 grades of membranes, which are available in two widths, ensuring customers have plenty of choice no matter which wind zone the development is in.
Extending our product range, we have also introduced Rewasi Top UV+ to provide roofers and specifiers with more options. Rewasi Top UV+ is an underlay made with Linopore® technology, which increases the product’s resistance to heat and UV, and therefore aging. Rewasi Top UV+ is classified as low resistance, or vapour permeable, which contributes to the ventilation of the completed roof.
To find out more about Danelaw underlays please get in touch with us through our contact page, or give us a ring on 01327 701 900. We will also be offering a course on our new learning platform, the Hambleside Danelaw Hub, about underlays, which will be available in the next few months.

A roofing contractor’s ethos that “only the best will do” has been recognised by a one of the leading quality national housebuilders.
Roof Plus, based in Chester, has been Redrow Homes’ preferred subcontractor in the North West for almost a decade, because of the quality of its work. That superiority has been recognised- again- with the winning of the 2019 Health & Safety Excellence Award at Redrow’s North West supply chain conference.
The Award is the latest Redrow accolade won by Roof Plus, complimenting Best Subcontractor NW and Subcontractor of the Year.
Where possible, Roof Plus installs Hambleside Danelaw products, using Danelaw Eaves Carrier and Low Profile Dry Valleys extensively across Redrow’s house designs, and Hambleside Danelaw’s innovative GRP roofing system Dryseal on flat roof dormers where appropriate.
“We have a positive culture towards quality in everything we do, from the products we choose to the way in which we install them and work on site. In our opinion, the Hambleside Danelaw range is the best on the market,” explains Roof Plus director Russel Witney. “That has clear synergy with Redrow’s provision of a quality home where only the best will do.
“All our work is completed ‘in house’ by directly employed roofers: thus they are committed to doing a quality job in all aspects, and have no reason to cut corners. All our roofers undergo thorough training, in product installation and site safety. It helps ensure optimum quality of build, done correctly, and thus minimising any future issues or remedials. We are not the cheapest, but the fact that we have such a long-standing partnership with Redrow proves we deliver best value.”
Adds Andy Fell, National Sales Manager-Dryseal at Hambleside Danelaw, “We know our products add value in their quality and ease of installation. It is great for our partner contractors to be recognised for the quality and value of their product and service.”

An award-winning roofing merchant reckons it is set to win even more, having added Danelaw GRP roof accessories to its portfolio.
Watts Roofing, founded just a decade ago, already has three branches across the East Midlands, and claims to be one of the fastest growing independent roofing merchants in the region. Its performance is endorsed by its winning of the Business Excellence Forum & Awards (BEFA) Best Manufacturer/Wholesaler trophy. Specialising in slates and tiles, it now stocks Danelaw’s full range of GRP valleys and roof ventilators.
“We aim to be the best, in product, service, customer support and speed of delivery,” explains director Shane Watts. “Local roofers are choosing us because we follow through on our promise, and are reliable. To continue to fulfil our ethos of offering the best, we switched to Danelaw, as we recognised the brand is the market leader in GRP valleys. We added the vents on top to give our customers a wider selection of products to choose from.”
The Danelaw brand of pitched roof ventilation accessories features a raft of pioneering- often patented- solutions designed to provide quality products that are fully compliant with all relevant Regulations, cost-competitive and roofer-friendly. The entire range of GRP roofing accessories is manufactured by Hambleside Danelaw at its state-of-the-art, purpose built factory in the heart of the UK.
A small development comprising of just 30 homes is now part of the picturesque village of Old Stratford in Milton Keynes.

Danelaw Open Valley for Slate Roofs
Morris Roofing and Leadworks is an established but expanding roofing contractor based in Bletchley, covering Buckinghamshire, Hertfordshire, Bedfordshire, Oxfordshire and Northamptonshire. As members of the NFRC (National Federation of Roofing Contractors) they offer quality service from inception to completion.
Morris Roofing and Leadworks were chosen for the installation of the slate and clay tile roofs on the Abbey Mill Homes project, incorporating three Danelaw dry fix products.
‘Dry fix’ are mechanically fixed products offering a mortarless application. The NHBC have recognised the advantages of mortarless dry fix products and encourage their use to reduce the risk of incurring future remedial works due to mortar failure. BS 5534 Code of practice for slating and tiling and NHBC require that all ridge and hip tiles now be mechanically fixed.

Danelaw Dry Fix Valley Trough for Tile Roofs
Danelaw CON6+ is a universal dry fix ridge and hip system, and was used on all the ridges. The patented gasket adds flexibility and allows compatibility with most commonly available ridge and hip tile profiles, including baby ridges.
The other products used were the original dry fix valley trough for the clay tile roofs and the open valley trough on the slate roofs. Both made from GRP, providing secure drainage for inclined roof valleys. The dry fix tile valley trough design eliminates the need for counter battens and special eaves closure pieces.
GRP products also offer advantages over traditional materials such as lead. They are simple and quick to install, have substantially lower costs than lead, no value to the thief, are thermally stable and have no harmful run-off or staining.

Danelaw CON6+ Ventilated Dry Ridge and Hip System
Lee Morris, Director of Morris Roofing and Leadworks and The Roofing Centre in Bletchley said ‘Danelaw products used on this project were easy to install and gave us peace of mind knowing that quality products were used in conjunction with the ten year guarantee we offer’.

Paul Rosevear with 30 years of experience in the roofing industry has completed a unique project at Plymouth Ferry Port.
The project involved three steel oil tanks with an ongoing issue of corrosion due to their exposed location at the port. Paul was asked to find a solution for protecting the top edge detail of the middle oil tank.

Martin Daw and Joe Reeves from RSL Plymouth recommended Danelaw’s lead alternative flashing; Fast Flash. Fast Flash is a flexible and fully self-adhesive flashing, perfect for waterproof
sealing.
After a successful trial, it was decided Fast Flash was the perfect solution for the corroding edge detail.
Before applying the flashing, it was important to clean off and dispose of any flaking material to the edges, followed by applying a primer to the rusted areas to ensure Fast Flash would adhere properly. It was cut into lengths of 800mm for ease of application to the 50m circumference of the tank. A J-roller was used to make sure the flashing had good contact with the surface and to take out any air.
The project took 5 days to complete; Paul said ‘Fast Flash is very easy to apply and very sticky which helped. It had a neat and clean finish similar to lead and I would easily use this over other lead-replacement products on the market’
There are plans for the other two tanks to follow suit after the successful application of the Fast Flash to the first oil tank.

Breckland Roofing used a mixture of Hambleside Danelaw Pitched Roofing products including the market leading dry fix valley troughs
Towards the end of 2016, Norfolk based contractors Breckland Roofing completed a new development project in Attleborough. The project featured a mix of 60 properties from housing association to affordable homes and private dwellings accompanied by a range of Hambleside Danelaw’s Pitched Roofing Products.
Approximately 200 Hambleside Danelaw dry fix valley troughs were installed along with the universal dry fix ridge and hip system and interlocking dry verge for tiles. When asked why Breckland Roofing uses Hambleside Danelaw, David, Site Contracts Manager, was extremely positive with the product quality, ease of installation and durability “We are very happy with Hambleside’s products and service. We can give them to the roof tilers to take to site and know they will fit them without problems”
Our tried and tested range of flashing products help to maintain a watertight roof, ensuring your roof junctions are durable and sound for years to come. Contact us for more information on our product ranges or visit our roof flashings section.
Hambleside Danelaw’s dry fix valley troughs have been keeping UK roof junctions durable and sound for 20 years. They have once again been specified again as the ideal product for a project located in Tiverton, Devon. Contractors Kilbride Roofing have been using Hambleside Danelaw for many years “we find the products to be well made to a consistently high standard, robust for site handling, easy to use and good value for money.”
This particular development for a UK based residential developer is currently ongoing, with approximately 200 HDL DVLPT’s already installed. The site of 250 houses is principally for open market sale but contains proportions of affordable and social housing.

HDL DVLPT – Dry fix valley trough for low profile tiles
The HDL DVLPT dry fix valley trough for low profile tiles is the perfect lead alternative, offering time and money savings on site. As well as the similar aesthetics, GRP has none of the associated health and safety risks that arise when working with and handling lead. Having no scrap value and deterring theft minimises the risk of further damage and losses on site during and after installation.
Alan Godfrey from Kilbride Roofing commented “We continue to use a wide range of pitched roofing products from Hambleside Danelaw and find their products to be reliable and good value, the sales staff is knowledgeable and the products are delivered promptly and efficiently.”
Take a look at our dry fix valley troughs for further product specifications and details.

Alistair Tirns, Project Manager at Graham Roofing commented, he was “very pleased with the ease of use of the product the high quality and the finished appearance” and that Hambleside Danelaw is his preferred choice of roof vent.
John Silverwright from the supplier, SIG Asphaltic, commented that he was “pleased with the product and service to this site for Dundee Council and Graham Roofing and will continue to use Hambleside Danelaw for further phases and projects in the future.”

Works started on a new housing development last June on part of the old Beach Coach Station in the centre of Great Yarmouth. The newly built Royal Britannia Crescent consists of nineteen houses with gardens and parking and is the first initiative from the Norfolk Development Company (NDC). Hambleside Danelaw’s original Dry Fix mortarless GRP Valley Trough has once again been selected as the best product for the complicated crescent shaped roof.
The crescent shape of the houses is a very shallow curve; therefore the number of useable roof coverings was limited. Shallow hips on the outside of the crescent would mean that the use of hip tiles would be unsightly and unreliable and on the inside of the crescent, open bedded valleys would be inconsistent with the overall design.
Norfolk based roofing contractors; Aspect Roofing chose our Dry Fix Valley Trough for low profile tiles for both the hip and valley detail due to their close-cut appearance on this new build project and the fact that they cut fixing time by up to 50%. Paul Elliston, General Manager at Aspect commented, “The proposition was for the product to be aesthetically pleasing and practical. Hambleside Danelaw’s Dry Fix Valley Troughs fulfil both of these elements at the same time as being easy to install and they provide good cover.”
The developer was extremely happy with the principle and the countless advantages that go alongside using this leading Dry Fix brand.
The ‘new for 2012’ two-storey Treehouses at the Centre Parcs Holiday Villages have been fitted with Hambleside Danelaw’s Dry Fix mortarless GRP Valley Troughs, meaning that Hambleside’s roofing products have yet again been specified for another project of a top quality brand.
Other prestigious buildings with Hambleside products installed are the McLaren F1 headquarters, the British Museum, London Zoo’s Gorilla Kingdom, Durlston Castle at a World Heritage Site, and Marks and Spencer’s largest distribution centre.
Roofed using cedar wood shingles, not a common choice of roof covering in the UK, the Treehouses at Sherwood Forest and Longleat Forest are designed for families or friends who want the ‘ultimate’ Centre Parcs experience with views of the forest. The luxury features include a games den and infrared physiotherm room.
Blue Lines Roofing Ltd with 25 years of specialist project experience chose Hambleside Danelaw’s Dry Fix mortarless GRP Valley Troughs in conjunction with Centre Parcs technical services because they complemented the Treehouses’ design and décor perfectly. John Boucher, managing director at Blue Lines, said: “We have been using Hambleside Danelaw’s products for 25 years. With their GRP valley troughs, you are getting good quality at a reasonable price.”
Hambleside Danelaw’s Dry Fix mortarless GRP Valley Trough creates a neat close-cut appearance on new build and refurbishment projects. It is ideal for complex jobs. Available in standard lead grey colour, the unique product cuts fixing time by up to 50%.

A high quality roofing solutions company has chosen Hambleside Danelaw’s Dry Fix mortarless GRP Valley Trough for a complicated roof on a Buckinghamshire care home. Malone Roofing went for the sustainable and quality solution offered by the British roofing products manufacturer when working in partnership with Castleoak on Lent Rise House, a new 60-bed care home in Burnham that forms part of Buckinghamshire County Council’s major Project Care reprovisioning programme.
Alan Stagg, contract manager at Malone Roofing, said:
“The new care home has a complicated roof by industry standards so we needed roofing and ventilation products that were ideal for a complex job. We have used Hambleside Danelaw’s Dry Fix valley troughs before and the GRP material is the best for this type of work, especially as it offers a high performance and mortarless solution.”

Cheddington Airfield played an important role in World War 2, as home of RAF operational training units. 70 years later, the estate is currently undergoing a re-generation scheme to modernise. Old and damaged Nissan Huts have been replaced with new steel fabricated industrial units to hold various new clubs and businesses and a new café has been constructed to service the business community.
The new build café is a single story brick building with a Double Roman tile roof. Hambleside Danelaw’s Dry Fix Valley Troughs for high profile tiles, HDL DVT/1, have been selected by Roof Craft from roofing merchant Advance Roofing, and now feature on the roof valley intersections. Roofcraft are experienced roofing contractors. They have been trading for over 25 years and have handled many jobs for local authorities in the Buckinghamshire area. Peter Thomson, Roof Craft, explained that he selected Hambleside Danelaw’s Dry Fix Valley Trough due to the obvious advantages of a mortarless option, plus the benefits of an installation process which is easy and straightforward and gives a neat, close cut finish.
JR Roofing installed Hambleside Danelaw HD TV15 series flush fitting tile vents across 150 roofs as part of a Community Energy Saving Programme, refurbishing Glasgow Housing Association building stock.
The tile vents were selected as a more cost effective option against competitor vents because of their unique increased airflow specification. At 15,000mm2 airflow, Danelaw’s tile vents can be installed at 1.5m spacings, whereas competitor vents with 10,000mm2 airflow would need to be spaced just 1m apart. Therefore on a project of this size, time and cost savings can be made whilst giving a high quality flush fitting finish.
JR Group have been committed to installing Hambleside Danelaw’s vents on refurbishment projects for this reason since discovering them 4 years ago. Whenever properties are being insulated to improve their energy rating, it is important to ensure adequate ventilation is also installed to avoid condensation.
The large farmhouse at Stone Shells Farm, Somerset, has recently been restored and as part of the project, some of Hambleside Danelaw’s products were selected for their high quality finish: Individual Dry Soaker for plain tiles (HD PCS), Conti-Soaker continuous dry soaker for tiled roofs (HDL CST) and Damp Proof Course (HDL DPC).
The builder, Mike Dunlop, saw our GRP products on display at Bradfords Builders Merchants and decided to use them rather than lead because he was concerned about the recent rise in lead thefts. The ease with which these products can be installed also appealed because of the cost and time savings.
Bradfords Builders Merchants is an established merchant with multiple branches in the South West. Hambleside Danelaw GRP flashings and roof, cavity and underfloor ventilation products are available from merchants nationwide.
Dryseal Flat Roofing
Dryseal Approved Contractor, Michael Wheeler at RCC Roofing completed this recent project at the St. Moritz Hotel in Wadebridge, Cornwall.
RCC Roofing were contacted to install a new roof for a villa at St Moritz. Michael stated: “The builder constructed an additional roof on the top floor, which we slated vertically using high-quality Spanish slates. We also applied a Dryseal flat roof to the dormer rooftop.”
As part of the project, RCC Roofing replaced the existing Velux windows with new and installed Cambrian slates—consistent with those used across most villas at St Moritz—on the remaining slate roof areas. This was a particularly challenging project due to the strict time frame, as the villa needed to be ready for holiday lets. All works were carried out under a temporary roof, ensuring efficiency and protection from the elements. RCC Roofing successfully completed the roof meeting the builder’s requirements and deadline.
Dryseal Manager Andy Fell said “As ever, Mike’s team delivered the highest standards of work in the minimum available time, always with the client’s best interests at heart. The neatness of the finished work speaks for itself.”



This new-build house is situated in the quiet village of Boothby Graffoe, Lincolnshire. The work shown in these photos was completed April 2023 by C & C Fibreglass of Lincoln, and covers approximately 150m² over five separate areas, finished with a modular ‘cassette’ sedum green roof.
The team from C&C Fibreglass trained in September 2022 and this was their first Dryseal project which they started immediately after becoming approved.
Director Phil Chapman said “The team found the Dryseal system straightforward to install and easy to achieve a good finish with”.
After carrying out an inspection on site, Dryseal Manager Andy Fell said “It was a pleasure to see work which had been completed to such a high standard and proving a credit to Phil’s team. We were delighted to issue the 20-year Dryseal ‘Leak-free’ Guarantee”.




This stylish bespoke house was designed and built to high standards in 2018, the aim being to achieve very demanding aesthetics. Set in spacious grounds which emphasise the good looks of the house, Phil Boardman of P Q Fibreglassing Ltd commented “The demanding standards of construction and the need to integrate our roof waterproofing with other trades posed quite a few challenges for my team”.
Over a 6-month phased construction period, the Dryseal team had to ensure a complete seal to hidden areas inside chimneys, forming complicated detailing around the architectural rooflights and dressing the multiple decorative ‘rib’ trims whilst ensuring that the demanding weather didn’t defeat their progress. Phil admitted “The job nearly beat us at times, but we worked as a team to produce a really good, finished product that I am delighted to re-visit after 5 years has elapsed”.
The 5-year inspection interval which is recommended as part of the 20-year leak-free Dryseal guarantee has revealed no major problems and confirms that the system is performing to expected standards with minimal future maintenance requirements.
Dryseal Manager Andy Fell said “It is satisfying to inspect a job that I first saw during the installation 5 years go performing exactly as designed. The quality of finish achieved by P Q Fibreglassing is commendable.”



Extension with Green Roof
Long established Dryseal Approved Contractor Martin Shaw of Martin Shaw Roofing was approached by ARC Design Projects Ltd and asked to install waterproofing with a green roof on this large single storey extension of a Cheshire property.
He proposed the use of Dryseal due to its proven track record, ‘zero-falls’ BBA approval and ideal suitability for green roof installations.

After training as a Dryseal Approved Installer in 2013, Martin has completed many Dryseal roofs in the last decade, and has a great working relationship with the whole Dryseal team.
This project called for the roof covering to be installed in 3 phases to allow for follow-on trades. The first phase called for the installation, fixing and lamination of the Dryseal pre-cured GRP sheet and other components, the second phase being the top coat finish.
The third phase saw the installation of a green roof cassette system from Sedum Supply.
To complete the roof perimeter detailing, a bespoke aluminium coping was installed, giving this sleek looking project a crisp finish.
Handed over in February 2023, complete with the Dryseal 20-year leak-free guarantee, this prestige project emphasises the importance of a supplying a first class material and installing it with first class attention to detail.
The Quays at Burton Waters, Lincoln is situated within 15 minutes of Lincoln city centre and blends a unique mix of distinctive, high specification homes with a variety of commercial properties.
This award-winning development is set amid beautiful Lincolnshire countryside, next to the Fossdyke Navigation Canal, and is just two miles by water from the centre of the historic City of Lincoln.
Dutch-inspired architecture featuring balconies and terraces offers stunning views across the busy marina. Many of the New-England style homes situated around the waterside development have waterfront gardens with private jetties and balconies, often available as holiday lets.
A variety of quayside businesses ranging from an architectural practice to restaurants, a coffee
shop and high-end bars means that the area is very busy, with most moorings fully occupied.
Completed in 2013, all commercial properties have large expanses of patio and balcony areas finished using the unique Dryseal GRP membrane roofing system installed by long-established Hull roofing contractor L A Hall Ltd.


E G Swingler & Sons Ltd were set a challenge by Princethorpe College in 2020 to re-roof building 23, install new rooflights, upgrade the insulation and fit a new guaranteed Dryseal roof whilst keeping the building weather tight.
These photos which were taken in October 2021 after work had been successfully completed and snagged in accordance with AT Architects’ specification show the newly installed rooflights and fully finished Dryseal installation.
Dryseal Manager Andy Fell explained “The re-roofing work was diligently carried out during the summer recess in 2021 and as well as the upgraded insulation and rooflight work, involved a new exterior plywood roof deck. Work was completed to a very high standard by E G Swingler and now carries the 20 year ‘leak-free’ Dryseal Guarantee”.
The waterproofing of Chelsea Heights, Sheffield was started in 2020 by Mark Dickens of P D Contract Services, a long-standing Dryseal approved contractor. P D Contract Services are a multi-facetted widely experienced company supplying and fitting slating and tiling, wet lay GRP and zinc roofing as well as their system of choice in this instance, the Dryseal GRP Roofing system.
Mark chose the Dryseal system as he recognised the long-established market-tested product’s excellent performance combined with Agrément certification and the high manufacturing standards of ISO 9001, providing confidence to both the client and the architect.
Totalling around 1,800 m2 this project has been on-going since 2020 installed observing the high standards set by main contractor and developer PTA Developments Ltd. Incorporating exposed main roofs, balconies with a number of “green” roofs incorporating a significant insulation layer throughout. Overall roofing completion is anticipated in mid-2022.
Dryseal Manager Andy Fell said “We have really enjoyed working with Mark on this prestigious project as it has grown and developed over the months, concluding with an excellent high standard of finished work”.
An Unusual Building with a Wide Range of Uses
Artisan honey bees, bespoke sliding rooflights to allow roof level access, protected deck areas with planters; these are just some of the unusual features of this cooperative housing development in Sheffield.
Sheffield Architect Ted Tunnicliffe of Tatlow Stancer Architects decided to specify Dryseal yet again as the roof waterproofing on this town house development, having been happy with the system on several recent Sheffield projects including a large housing scheme and a health care clinic.

Andy Fell, Dryseal Manager for Hambleside Danelaw said “Having worked with Ted successfully on several projects since 2016, we were delighted to be able to help and have the opportunity to work on this specification. As you can see from the photographs, work has been completed to a high standard by Sheffield firm Cure Roofing who as ever completed their work with care.”

Before the roof was refurbished
At the end of its service life, you have the option to refurbish and apply a new topcoat, increasing the duration of the protection Dryseal offers. Customer Garth Jeffrey had his Dryseal roofing system installed two decades ago and decided it was well worth refurbishment.

In progress
He said: “My 20-year-old Dryseal roof had been fully watertight with no leaks and I was so satisfied that I decided to refurbish the roof to extend its life by another 20 years. Work to prepare the original covering and apply a new Dryseal top coat was completed in 2020 by MEH Builders & Joiners of Galashiels and I am very pleased with the results. The product is excellent, as was the service from MEH”.
Dryseal Manager Andy Fell added: “This is yet another great example of the Dryseal system successfully completing its first 20 year stint, with potential for another 20 years of extra time after a straightforward low cost top coat refurbishment. We are again delighted to be supplying added value and customer satisfaction whilst illustrating the sustainability of the Dryseal system”.

New House…
Dryseal is chosen again in preference to zinc.
This newly built project in Boyle Co Roscommon was originally intended to be finished with metal sheet but this was subsequently changed to Dryseal in 2018 after discussions with the architect.
The original design had been for a “standing seam” metal clad roof, but it was decided that the pitch was too low for a metal finish and with so many joints on such an exposed site it was deemed to be potentially prone to leaks, so the Dryseal GRP waterproofing membrane system was chosen.
Initially installer P Q Fibreglassing Ltd had decided to fit 18mm OSB3 on top of the 200mm insulation so they could then easily fix the standing “zinc” seams down. As this was potentially going to add a lot of cost, P Q Fibreglassing’s Phil Boardman said “We decided it was best to remove the OSB3 and then use Dryseal DP 40 stress plates with 240mm screws under all the simulated zinc seam upstands, choosing pop rivets to fix the zinc seams down to the flat sheet, hiding almost all of the fixing points and resulting in a neat, flat finish”.
Top—coated in a bespoke dark grey, the project was completed and handed over in 2019 to a very happy customer.
Neat work beats zinc!
Mihai Oprisan shows the way with first class construction and finish.
This beautifully finished residential extension was completed and handed over in July 2019 after a great deal of hard work and attention to detail.
Rather than opting for a traditional metal roof, Mihai chose to use the Dryseal system for cost and aesthetic reasons. As you can see from the high standard of finish on all elements of the extension and garage, Mihai is very uncompromising and strives to leave the best possible result for the client.

Technical Manager John Godley said, “In over twenty years of working with new Dryseal installations, I have rarely seen such high standards of work, which are a testament to Mihai’s attention to detail”.
The use of the Dryseal “rib” trim that you can see in these photographs involves careful attention to detail from the Dryseal installer but can lead to exceptional results as you see here, the added benefit being cost savings compared to a metal raised seam system.
Dryseal Manager Andy Fell is quoted “It is so heartening to see that pride in the job is still alive and kicking!”

Far from being a “pig sty”, this interesting bespoke self-build house belonging to Mark Elsigood at Church Stowe in Northamptonshire is due to be finished in late 2019. The building was named the “Pig Sty” to mark the location of the original building and was built by Mark himself with additional specialist sub-trades.
Mark chose to use Dryseal because of its strength, suitability for “green” roof waterproofing and for the renowned 20-year Agrément certified guarantee. The Dryseal was successfully installed by long-established family business E G Swingler Roofing who are also based in Northamptonshire.
Mark picked the Dryseal GRP roof membrane system having visited Stand 106 at the The National Self Build and Renovation Centre in Swindon, which is open every day attracting over 17,500 visitors per year to 250+ exhibits.
The National Self Build & Renovation Centre’s Managing Director, Harvey Fremlin, said: “As the UK’s only permanent self build visitor centre, our mission is to inspire, educate and offer impartial advice. We are delighted that Mark discovered the Dryseal system at the NSBRC. Andy and the team work hard to give our visitors great advice and service. The Pig Sty looks absolutely fantastic, and proves that self build allows people to create bespoke homes that suit their taste, budget and life-styles.”
You can see from the unusual design that the roof incorporates two balcony areas finished with stainless steel edge rails and tempered glass balustrades, providing both first-class visibility and safety, and allowing clear views of the nearby open countryside. The two balcony areas are planned to be finished with “sedum” mats to form a “green” roof.

Dryseal Manager Andy Fell said “We are pleased that Mark chose the Dryseal system to waterproof his new home and are very happy to have also supplied our 20-year “leak-free” Guarantee“.
After the project was complete, Mark said “Visiting the NSBRC allowed me to observe different products and their suitability for the self build project I was undertaking. Dryseal seemed to have all the characteristics that I needed in a flat roofing system. I am really pleased with the final results of the Dryseal system in waterproofing my dream home“.
Ceardean is a team of experienced architects, designers and specialist consultants based in Dublin 8. The practice aims to deliver aesthetically appealing buildings, working in strong collaboration with clients to achieve cost-effective and functional designs every time.
Such is the passion for energy-saving design within the Ceardean practice, that Chief Architect Derek Trenaman RIAI spent 5 years converting his 100 year old cottage in Sligo into a beautiful zero-energy dwelling

This pictured project in Crumlin, Dublin has almost doubled the usable space available, adding a contemporary flavour to what was a standard semi-detached dwelling. Using an innovative rainwater system that effectively hides the points where water discharges from roof level and using a beautiful larch exterior cladding to powerful effect, the crisp clean lines of the building make the corner of this Dublin street look really special.
Phil Boardman of PQ Fibreglassing Ltd said “Yet another high end Dryseal membrane roof completed with the all-important 20 year guarantee and insurance certificate marking over 6 years of continuously successful Ceardean Architect specified contracts.”

Over the last 25 years, Dryseal has been used as an underfloor damp-proof membrane in a gymnasium, a liner for ponds and fountains, a damp-proof membrane in a lift shaft on a castle, and recently as a roof covering for a Container Home.
In early 2018, Phil Boardman of P Q Fibreglassing Ltd was asked to quote for the waterproofing of three sea containers which are now in use as storage units on the quay side at Dun Laoghaire Harbour, on the outskirts of Dublin.
The containers have a reinforced roof incorporating raised areas that act as structural ribs to give the steel roof rigidity and strength. Phil’s team levelled the roof surface using sheets of 25mm insulation board, leaving an even surface to work to. They then fixed the Dryseal system through into the steel roof, formed the laminate joints and finished with dark grey top coat.
A lightweight robust and flexible waterproofing membrane was called for and Dryseal was chosen for its superior properties.
Phil said “The priorities were to ensure that the system was securely fixed, completely waterproof and salt resistant. Dryseal fitted the bill all round”.

Loud the Winds Howl, Loud the Waves Roar. The Roof Used to Leak, Now with Dryseal… No More!

In 2017, Steven Gillies of R S Gillies was approached to quote for re-roofing a 250 m² area of this historic hotel. Despite the rest of Scotland suffering from the Siberian weather and 300mm of snow, the warm Gulf Stream weather enabled Steven and his team to put aside their day-to-day boat building work and complete the re-roofing with the minimum of disruption in February 2018.
Steven said “We are really impressed with how easy the Dryseal system was to install and the high standard of finish we have been able to achieve. It’s great to know that we have helped preserve the fabric of this historic hotel”.
R S Gillies trained to install the Dryseal system back in 2013 , but have been so busy building boats at their yard in Kyleakin that this project represents their first good-sized roof since completing the course. Steven started his business over 20 years ago with initial support from the Prince’s Trust, Prince Charles’ charity to help young people thrive.
Mike Lemmon, Scotland Area Manager for Hambleside Danelaw said “A great finish to this project after a lot of hard work. We have enjoyed working with Steven and his team and look forward to the next job”.
During the summer of 2016, Dryseal Approved Contractor John Cossey of Ashford, Kent was approached by Vinci Facilities. Acting for Affinity Water, Vinci asked John to provide a waterproofing solution for the tired bitumen felt roof covering on this facility. The building which was built by the Folkestone Waterworks Company in 1932 was starting to show signs of ageing at roof level, and John decided that Dryseal was the obvious system to provide a long-term waterproof covering on this complex roof.
John Cossey said “Dryseal was ideally suited to extensive detailing to metre high parapets and sundry awkward interfaces. Work was completed successfully in January 2018, with a 20 year “leak free” guarantee”.
Another guaranteed success for Dryseal – Waterproofing the Waterworks!

This extension as part of a full house refurbishment on a property in Woodstock Road Oxford now benefits from a new Dryseal green roof.
Completed in June 2017, the Architect at the Client’s request specified this attractive and environmentally-friendly design. Dryseal, being the ideal waterproofing membrane for a green roof, was a natural choice, due its robust, aesthetic and non-pollutant properties. Bondright Roofing Services’ Erika Luckow said “We were contacted by Lee & Ross Architects in May 2016 following a CPD Seminar held by Hambleside Danelaw. We were told that they found Dryseal to be an attractive solution for their project in Oxford requiring a Green Roof system over the kitchen/family room on the extension. With the assistance of Andy Fell at Hambleside Danelaw, Dryseal was specified for the 37m² warm roof, finished with the ANS GrufeKit Green Roof sedum system and Scottish cobbles.” The installer Dawid Piasecki said; “The fitting was easy and was installed according to the manufacturer’s instructions; Dryseal is a really good system.”
The finishing touch?
The 20-year Dryseal insured water tightness guarantee.
Skerries (Irish: Na Sceirí, meaning “The Rocks”) is a seaside town in County Dublin, Ireland. The name comes from the Norse word skere which has descended into the Irish word na sceirí.

A lovely seaside resort with “picture postcard” characteristics, Skerries is very popular with visitors from Dublin for a weekend break or family summer holiday, with kite-surfing and water sports being high on visitors’ lists along with the high quality local seafood restaurants. The housing development at Ballygossan Park is proving very popular and is filling rapidly; almost as soon as each property is completed, the sale goes through!
There are 2,500 m2 of Dryseal roofs completed up to date on this site. Most of the new house types have a flat roof, varying in size from 10 m2 dormers to 90 m2 of main house roof. The dormers are fitted with decorative trims to imitate zinc on the cheeks and faces, with the top coat being specially blended to suit the architect’s choice of colour.
We are told that the first phase of development is for 102 houses with plans for a railway station, shops, and a school in the pipeline. The development is at the half-way stage, with construction by Noonan Construction continuing apace.
Dryseal Approved Contractor P Q Fibreglassing Ltd have been instrumental in introducing Dryseal to the Client and Architect and have completed all roofs to a very high standard.

The first installation was completed in 2016 to waterproof the Hub, including the Main Entrance and Circulation Area.
Construction is due for completion by O&D Construction Ltd during September 2017.
The Architect for this phase was again Plan A. Glenthorne High School is one of several school projects where Plan A have preferred Dryseal over other roofing membranes.
Plan A’s Architect Director Paul Ginever said “The school were very keen to invest in a product which would serve them for a long period of time rather than opting for a short-term cost saving option, and it was a decision that we were very happy to support. We have specified Dryseal on a number of public and private projects with confidence that it would contribute to the long-term robustness of the building fabric. We are very happy with the
finish and quality of installation”.
Dryseal Manager Andy Fell said “McGrath Roofing’s work enhances the qualities of Dryseal as a warm roof covering, as well as emphasising the versatility of the system when used for vertical work and detailing such as coping ecapsulation. We are delighted with the standard of installation and finished work”.

Bondright were keen to use the Dryseal system and Ressance proved to be receptive to the idea, as they had had a number of problems on projects where they had previously used pvc ‘single ply’ waterproofing.
Dryseal Manager Andy Fell said “A meeting with Nick Turner, Ressance Director of Design and David Creek, Project Manager proved to be successful in promoting the resilience of Dryseal along with the many industry accreditations which the system carries. The insured 20 year Guarantee also played a strong part in the presentation”.
Work commenced on the roofing installation on October 2015, with a high specification 0.13 W/m2 K U value being achieved using 150mm insulation over the existing woodwool decked structure. Despite some testing weather in October and November, Bondright rapidly achieved water tightness on both blocks totalling over 900 m2, and handover in early 2016.
Merchants Court is a short walk to a number of convenience stores, food outlets and Victoria Park, within walking distance of the town centre and transport hubs and just 600 metres from the Kennet and Avon Canal. Further details of the stylish development can be viewed on Ressance Website.
With everyone happy to have achieved a positive outcome on this prestigious project, we keenly look forward to working with Ressance again in the future.



Hull City Council, Trowbridge Housing, Bellway Homes, Trent & Dove Housing, Magenta Living…. and many more. These customers have one thing in common with Newark & Sherwood Homes whose properties use Dryseal on a range of flat roofs, bay tops and new build sheltered accommodation.
January 2016 saw a meeting with Newark & Sherwood Homes which resulted in Dryseal being specified for their re-roofing programme on flat roofs in the Edwinstowe, Boughton and Wellow areas of Nottinghamshire.
Work started in June 2016, with around 50 nr upgraded warm roofs now complete – well on the way to the anticipated 200 units which the contract should generate. Hambleside Danelaw have been working closely with contractors Malden Roofing and Cure Roofing, both of Sheffield, who have been working in tandem to provide a first class guaranteed result.
Dryseal Manager Andy Fell said “Dryseal is ideal for these types of roof – able to withstand some fairly heavy treatment whilst looking good and being easy to maintain. Housing Associations who are under pressure to cut costs after the 2015 Maximum Fair Rent rule changes continue to appreciate the long term ‘whole life’ cost benefits of the Dryseal flat roofing system. The peace of mind of our 20 year insured guarantee is the icing on the cake for the client. The system is only as good as the installer and these finished roofs by Malden and Cure Roofing are of a very high standard.”

Dryseal Approved Contractor Croft Roofing have been supplying and fitting Dryseal since 1995. Owner Tim Croft was approached by his long-standing customer Andy Harm to recommend a solution to roofing problems at Otley Golf Club. Local builder and Club member Andy had been asked to assist Secretary Peter Clarke in solving water ingress problems on the 270 m2 flat section of the Club House roof.

After an early inspection carried out in conjunction with Hambleside Danelaw, Tim found that the existing EPDM membrane covered roof was in need of an upgrade due to low levels of insulation, water ingress and ponding problems. Ejot were asked to recommend an approved fixing and carry out ‘pull-out’ tests to ensure the security of the fixings.
As the roof covers the Entrance area, Lounge and Kitchen, Tim’s workforce had to be very careful in carrying out their work. This included adding insulation, improving drainage and installing the Dryseal system whilst causing the minimum of disruption to the running of the 700 member Club. They also encapsulated the front parapet wall and replaced the original aluminium capping using joint-free Dryseal sealed copings, to minimise the chances of future problems.
“Croft Roofing have been very good and have been completely professional. The work proceeded as quoted and agreed, on time, within budget with excellent results” – Peter Clarke – Club Secretary
The original rounded river ballast finish was put aside during re-roofing work and then replaced on a new fleece layer to the main flat area, to minimise the chances of any of the original standing water being visible. In the event, the drainage measures taken by Tim’s employees resulted in a 90% reduction in the original ponding problem – a great result.
A final inspection for Guarantee was completed in July 2015, followed by completion and handover to another satisfied customer.
Dryseal was the material of choice for the green roof waterproofing on a recently constructed ‘Passive’ House in Easter Housebyres, Melrose, Scotland. The term ‘Passive’ house (Passivhaus in German) refers to a rigorous, voluntary standard for energy efficiency in buildings, reducing their ecological footprint. It results in an ultra low-energy building that requires little input for space heating or cooling.
Malcolm Horsburgh of MEH Builders and Joiners chose robust and lightweight Dryseal to line the green roof on 130m2 of the main roof and 56m2 of the lower area and balcony. GRP was specified by the architect for the roof membrane and approved contractors MEH felt Dryseal was the obvious choice.
The Dryseal system is ideal for green roofs as it eradicates the need for a root barrier. The superior roofing material is also safe with potable water, as there is no contamination from the surface that might interfere with growth of the vegetation. Dryseal has other environmental advantages; it has the lowest embodied carbon of all its competitors (for more information, please contact us).
Malcolm from MEH said: “By using Dryseal as opposed to other GRP ‘wet lay’ products we were able to leave out the additional layer of plywood required for wet lay systems and increase the thickness of insulation by 20mm. More to the point, we also saved the client money!”
Building the Melrose ‘Passive’ House began in January 2014, with the project due to be finished in January 2015. The site is on a slope, making the build tricky at times, but the Dryseal went on smoothly, taking four contractors only 6 days to install. Owner Patricia Touw said Malcolm and his team paid “great attention to detail”.
The Dryseal system carries a 20-year leak free guarantee with an insurance warranty; a perfect choice for your roof.

The work started in September; approved Dryseal contractor Hamish Graham worked on the project with his team at G C F Joiners. The contractors installed 40m2 of Dryseal on three dormers; the work was executed with precision and only took two days. G.C.F. Joiners and Contractors Ltd commented,
“G.C.F. Joiners and Contractors Ltd are honoured to be chosen for such a prestigious project and look forward to carrying out future works”
Dryseal is used on many heritage projects due to its excellent durability. As those who install Dryseal have to be approved contractors, the work carried out is always first class. Dryseal emulates the classic lead look as it can be finished using decorative roll trims to imitate a heritage installation.
The Castle is located on the West Coast of Scotland, in Lochaber. The striking Mingary Castle, which is set in a classic Highland landscape, was used as a stronghold protecting the north end of the Sound of Mull, and the more southern islands of Tiree, Coll and Eigg. The Gaelic architecture remains as imposing now as it did back in medieval times.
The Castle’s restoration is due to the owner, Donald Houston, setting up Mingary Castle Preservation & Restoration Trust. A huge amount of work is going into the restoration of the heritage building, with local craftsmanship leading the effort. To read more about the project visit www.mingarycastletrust.co.uk/mingarycastletrust/.
Hambleside Danelaw is pleased to be involved in the work, and Dryseal is the ideal component for the future of the castle. For further details on Dryseal or how to become an approved Dryseal contractor, please call 01327 701900 or email dryseal@hambleside-danelaw.co.uk.

Dryseal system budget prices were incorporated into an extensive improvements programme and work began in 2013 after the usual rigorous tender process. Dryseal Approved Contractor Avonside Commercial & Industrial Roofing (Midlands) started work on the Sports Hall, introducing additional insulation whilst fitting the Dryseal RibTec membrane over the existing coverings, after suitable preparation. The re-roof was carried out in tandem with Whitesales who were engaged to install the new triple glazed rooflight units. Work was successfully completed after six weeks in late 2013, with the newly watertight Sports Hall quickly attracting positive comments due to the improved insulation level and brighter interior.
The main lower level Gymnasium and Dance Studio roofs totalling over 1,000 m2 were re-roofed over a busy 8 week period between March and May 2014. Once the chippings had been removed, the existing waterproofing was again able to be retained as a vapour check layer, adding 50mm of Celotex TD 4000 polyisocyanurate insulation board in the Dryseal over-roof. Various items of redundant plant and equipment were also removed from the roof at the same time as re-roofing. The whole operation was able to be carried out whilst the building was in daily use and was completed without disruption to the Centre, thus ensuring important uninterrupted income.
Another successful Dryseal roof refurbishment completed on time and within budget, prompted Dryseal Manager Andy Fell to say “This effective and efficient re-roof illustrates the major benefits of the Dryseal component based GRP roofing system when used in a refurbishment scheme. Speed, cleanliness, improved insulation and lack of disruption all contributed to the high level of satisfaction expressed by the Management of the Leisure Centre.
The highly regarded St Joseph’s Surgery and Diagnostic Centre in Sligo, Ireland was urgently in need of a new roof covering over the main hospital building. After several months of discussion, the hospital chose to use the Dryseal component based GRP roofing system supplied by Approved Installer PQ Fibreglassing to complete the re-waterproofing and insulation upgrade works. The 750 m2 area comprised six roofs covered with failing rock asphalt on the original concrete substrate.
The Hospital was closed on a Thursday in April 2014 to allow the car park to be used for a crane to load out all delivered materials to roof level, to ensure that roof level production would be maximised. PQ Fibreglassing’s dedicated team of seven then worked over six long weekends, whilst the hospital was closed, to ensure that the day-to-day function of the building would not be compromised.
One of the main aims of the project, in addition to the replacement waterproofing system, was to reduce the hospital’s considerable heating costs. This was achieved by introducing two layers of 50mm Kingspan TR26 insulation to form a ‘warm’ roof build up under the Dryseal membrane, using the original asphalt as a vapour check layer. PQ Fibreglassing also renewed eight roof lights with new high thermal efficiency triple glazed Velux units.
The addition of DukMat safety walkway matting and self-weighted perimeter safety handrail ensure that the newly installed Dryseal roof can be safely inspected and maintained to ensure its longevity. With a 20 year insured guarantee that can be extended in year 19 by refurbishment of the top-coat, the Agrément certified system can have its life extended almost indefinitely.
A 35% reduction in heating oil costs is an immediate positive outcome of the roof’s insulation upgrade. Having used the Dryseal Flat Sheet membrane system finished in dark grey to eliminate all roof leaks, the hospital’s Premises Manager referred to this as a “perfect” result.

After installing a temporary waterproofing structure, the church took action by ringing Hambleside Danelaw about the Dryseal system. They had found out about the extensive Dryseal work done in Bromsgrove at the St John the Baptist church in 2012.
Dryseal Manager Andy Fell said “I was called by Brian Cooke from the church Fabric Committee. Brian was extremely annoyed about the theft, but fairly stoical about the fortunes of the church compared to other less fortunate ones. He expressed a keen interest in Dryseal and was sent some technical information along with photos of other church work. Within days, Approved Contractor Paul Lambert of Paul’s of Burbage had inspected the roof and quoted. The quotation was accepted in early 2014 and the Dryseal RibTec re-roofing work completed in April 2014”.
Sadly, the organ which was newly installed in June 2013, is situated in the South Aisle and stands directly below where the lead had been stolen from the roof. It was severely damaged as a result of the lead theft and had to be repaired at considerable expense to the church, as insurers would not provide adequate cover for the theft of metals from roofs. Now fully restored, the organ is being used once again. Church services and other activities can also now be held in the church this year without fear of further lead thefts and floods in the south aisle. This includes the series of annual classical concerts , now in its 43rd year which attracts widespread interest from the surrounding area. Details can be found at www.musicatleamingtonhastings.co.uk
Paul Lambert was extremely pleased with the finished roof “We installed the Dryseal system, complete with imitation rolls and roof void ventilation along the whole roof on both levels. The lead that was left behind by the thieves was sold to a scrap yard and paid directly back to the church. We are extremely happy about the job, the church were also very pleased with the finished roof and the time taken”.
Hambleside Danelaw are delighted to have been able to assist in preserving a part of English history with another memorable Dryseal project.
Hambleside Danelaw’s component based roofing system Dryseal has been selected for a complicated domestic roofing project on the edge of the popular Devon village of Stoke Canon.
The Round House is a remarkable four-bedroom house that was designed by architects Peter Blundell-Jones and Gillian Smith. Completed in 1976, it was originally built for the parents of Blundell-Jones as their retirement home and was his first project. Having never before been on the open market, the Round House has now been sold and is being completely renovated – including the replacement of the original felt roof covering with an insulated Dryseal system.
The new owners, Martin and Christine Cridford wanted a replacement roof that complimented the design of this interesting house. They considered the roof to be a main feature of the building and wanted it to have a good appearance from the garden. They originally looked at installing a new metal roof. This was going to be costly and many metal roofing contractors were unwilling to take on the job as it was too complex. Those who said they could do it wanted to strip the roof structure completely and cover the house with shrink-wrapped scaffolding to keep it dry while the works were carried out. This proposal did not fit in with the owners’ ideas and other options were explored.
In February 2013 Martin approached Dryseal Approved Contractors DA Somerwill about the Dryseal alternative. David Somerwill and Andy Fell, Dryseal Manager carried out a full roof survey and confirmed Dryseal as a sensible and cost effective solution. Hambleside Danelaw formulated the specification for the renewal of the roof covering including a 20 year insurance backed guarantee.
Dryseal can usually overlay existing roofing material so there was no need to need to strip the original roof covering in this instance. Laid over a 50mm insulation board to further enhance the U value of the existing wood wool slabbed structure, the Dryseal was fixed using SFS Intec TPR-L aluminium peel rivets and DP40 nylon stress plates. The appearance of a sheet metal roof was achieved by the use of carefully spaced decorative roll trims and dark grey polyester top coat.
Martin and Christine commented, “We are very pleased with the final appearance of the roof and the attention to detail by David Somerwill and his team. We know they are very proud of the completed roof. The Dryseal guarantee gives us peace of mind that we have a roof that will last into the future. With Dryseal the house has the roof it should have had when it was built.”
The Dryseal system is ideal for flat and low pitched roofing and is manufactured in the UK.

The roof had previously been renewed using an asphalt covering which had failed after only five years, causing water ingress to damage the original roof deck. LEP opted to install a scaffold and sheeting temporary roof over the whole building to protect the interior whilst the work was undertaken. Plywood and a vapour control layer were fitted to replace the damaged roof deck and the insulation was upgraded with a tapered PIR insulation system, finished with the Dryseal system. New rooflights from Coxdome were also incorporated into the project to enhance the quality of natural light into the interior of the cottage.
The works were carried out by Dryseal Approved Contractors Allied Roofing (NW) Ltd. When complete, the building was completely watertight and the occupants of the cottage have commented on how much warmer and brighter the inside of their home is now. Allied Roofing showed respect to the community with minimum disruption to the neighbours, who had been especially concerned about potential noise and upset during the works. Care also had to be taken not to interfere with the roof of the adjoining transformer building in view of the stringent conditions imposed by the local Utility Company.
Andrew Kepczyk, lead designer for LEP commented, “We needed something with guaranteed material and workmanship that would provide certainty for the charitable trust. The representatives involved from Hambleside Danelaw had a clear understanding of their material and our requirements. The support we received at design stage contributed greatly to the success of the completion of the work.”
Another successfully completed project benefitting from the Dryseal 20 year independent insurance backed guarantee and warranty.

Chosen for its robust nature, 20 year guarantee and ability to mimic the appearance of a lead sheet roof, Dryseal was installed at the National Trust’s request by Rowsell Roofing of Yeovil, an approved Dryseal contractor, in March 2013.
The refurbishment involved the removal of a dilapidated fibre cement sheet roof from the conservatory, the decayed decking and felt roof over the Utility area, with re-instatement using Dryseal fitted over plywood. The Dryseal was finished in dark grey with a UV protective top coat and completed with decorative roll trims to give a lead effect and lead-like appearance.
Dryseal Manager Andy Fell said “Nick and Nathan of Rowsell Roofing completed a first class job with exemplary attention to detail and a pride in their work that is a joy to see. The feedback from the client echoes this”.
Hambleside Danelaw is delighted to be a part of another National Trust project in Buckinghamshire. Marlow Place, a 17th century Georgian property is in need of new flat roof areas and guttering and it has been requested that Dryseal replace the lead sheeting due to its proven reputation as a sensible alternative to lead.

Stolen lead replaced with Dryseal
In June 2012, it was reported in the local press that Hythe Bowls Club, in Kent, had become yet another victim of the lead theft epidemic rife in England in recent years. Their clock tower roof had been stripped of lead by thieves and the timber structure left open to the elements. Hambleside Danelaw were alerted to the problem and our Dryseal Manager Andy Fell passed on the details to the local Approved Dryseal Contractor, John Williams & Co (Contracting) Ltd of Lympne, Kent.
It soon emerged that, not only were John Williams familiar with the Bowls Club, but they had also originally installed the clock tower structure and lead covering, when the pavilion had been built. John Williams quickly got in touch with the Bowls Club, paid a visit and surveyed the damage. They quoted to re-instate the roof covering with Dryseal and, within days, the Bowls Club clock tower roof was as good as new.
Being manufactured from GRP (Glass Reinforced Polyester), Dryseal has no scrap value and is therefore of no use to thieves. As you can see from the photograph, the new Dryseal covering looks in keeping and blends in well with the building, the original weather vane having been retained and secured over the new roof covering. Another satisfied customer!
Is this the ultimate test for a glass fibre roofing system?
One of our Dryseal Contractors Mike Williams of FuturA Roof Limited has recently completed the construction of a Bob Cat model jet aeroplane.
It is propelled by a Wren 44 gold turbine, but the interesting bit for us is that the wings have been joined to the fuselage by using the same laminating components that we use within our Dryseal fibreglass roofing system.
Not only that, but our new stress plate, code DP 40, has also been used within the construction. The model has successfully flown at speeds in excess of 200mph (330km/h) and has endured 5 g forces during sharp banking manoeuvres. The model plane has been photographed in flight by Alan Townsend and this photo shows clearly the wing section and the stress plates all in action!
That’s very fast for a Dryseal flat roof which is usually stationary, although it has been used to provide the roof surface on a railway carriage – but that’s another story!

Dryseal used on a ‘barrel vault’ shaped roof
Dryseal has been installed on a Georgian period house in Vergemount, Dublin. The client, who happened to be a qualified Architect specified Dryseal and Approved Contractors, PQ Fibreglassing based in County Longford, Ireland, were appointed to complete the works. The building is overlooked therefore the architect stressed the importance of a high quality, neat and flat finish. When comparing alternative roofing options, Dryseal was the best product for the job.
One of the roofs was a traditional ‘barrel vault’ which required specialist skill to achieve the impressive results, cleverly using roll details and other Dryseal trims, making the end product look like a clean lead finish. The client is thrilled with the results and will be specifying Dryseal in future projects now that its versatility has been proven.
In Woodlesford, West Yorkshire, the former church of All Saints has been converted into residential accommodation. As part of the conversion, the old spire was removed and the roof space capped in keeping with the building style. Dryseal was chosen to fit the budget whilst having a lead-like appearance, especially with added lead roll detailing.
9 years on, our Technical Manager John Godley was passing the building and had the opportunity to take a photograph, demonstrating how effective Dryseal has proven in this lead replacement installation.

Covered with a variety of materials, the 3 main roofs spread out over 1800 square metres comprising Technology, Sports and Teaching blocks. Hambleside Danelaw’s Dryseal roofing system offered an instant practical lightweight solution with a high quality finish.
As Dryseal is a component based mechanically fixed system, it allowed an additional 60mm of rigid insulation board to be overlaid directly onto the existing roof providing cost effective and instant waterproof protection. Due to the unique nature of Dryseal any moisture left in the old roof would be dissipated through roof edge ventilation possible by not sealing the edges. The roof was finished in a bespoke pale blue (RAL 5024) top coat to match one of the colours of the school crest. The top coat, which provides protection from UV degradation, is usually supplied in light and dark grey as standard but can be customised to match a range of colour finishes.
Hambleside Danelaw believe that a major precedent has been set for churches and other historic buildings by the first ever installation of a modern glass reinforced polyester (GRP) roofing system on a Grade I listed English church.
This precedent could help many other churches and heritage buildings blighted by the current lead theft epidemic or by other forms of roofing damage. The British manufacturer of the roofing system also believes that the installation will do much to counter the outdated image of ‘cheap’ fibreglass alternatives for roofing repairs.
Plagued by no less than seven incidences of lead theft from its roof since April last year despite having anti-climb paint and motion sensors, St John the Baptist (Church of England) Church in Bromsgrove was forced to look at alternative roofing materials when faced with an unaffordable lead replacement bill of £275,000 and no further opportunities to make a claim on its insurance.
The church opted for the Dryseal component-based GRP system manufactured in the UK by Hambleside Danelaw, a roofing products company that has previously won a Queen’s Award for Innovation and received an environmental award from David Cameron. The church’s decision was initially met with strong opposition at many levels in the statutory approvals process for a Grade I listed building, but eventually an application to Chancellor of the Diocese of Worcester led to approval being given to repair the north and south aisle roofs on the building which dates back to the 11th century.
Work on the GRP roofing installation which began before Christmas 2011 is now complete and the church is delighted with the results, knowing that that there is no sell-on value for criminals in the new material.
Commenting on the Dryseal GRP system, the Reverend Chris Wingfield, Priest-in-Charge at St John’s, said:
“It looks like lead, it’s got longevity and it will save this church for generations to come.
We had to fight our corner, but we were caught between a rock and a hard place. It was not cost-effective to use lead or terne-coated steel. English Heritage see lead as the best product, but in the current financial situation, you need to use the most cost-effective material.”
GRP less expensive than lead but not a ‘cheap’ material
The church spent £51,000 to replace the roofs with Dryseal rather than the £275,000 it would have needed to raise to use lead.
The advice behind the ground-breaking specification came from Geoff Stollard, a local construction consultant by profession and a member of the St John’s choir, chair of the fabric committee and the project lead.
Geoff Stollard said:
“Everyone at St John’s is extremely positive about the outcome and the quality of the work has been commended as being to the highest standards achievable with attention to detailing exemplary.
“The active co-operation of Hambleside Danelaw throughout the project was also asked by the Reverend and the church wardens to be placed on record and in particular the support provided by John Godley and Andy Fell through regular inspections of the site.
“Lead theft is not a victimless crime. The victims are the church congregations at the heart of their communities, working hard to keep historic buildings open for worship and available to serve the areas where they live in a whole variety of ways. Coping with one theft of a church roof is disheartening; coping with successive thefts, as is often the case, is heartbreaking. Installing a modern GRP roofing system puts a stop to this.”
Hambleside Danelaw maintains that this precedent means that the perception of all fibreglass materials as ‘cheap’ should be consigned to history.
Commenting on modern GRP, Chris Avery, the company’s managing director, said:
“‘Cheap’ is a strange term for a material where the raw material prices can exceed £4,000 per tonne, whereas materials typically used within ‘plastics’, so readily accepted into our everyday life, cost considerably less.”
The company points out that the versatile modern GRP material offers an excellent service life, strength and eventual recyclability. In comparison with other materials, it can be light in weight, translucent or opaque, and carefully profiled to match other building materials such as metal profiles. To achieve that though, the manufacturing investment cost for producing pre-cured GRP as roofing profiles, flashings or cladding is considerable and is a world away from the perceived ‘bucket and brush’ approach so often associated with GRP.
Chris Avery added:
“GRP is a competitive material providing excellent solutions for the building industry and our customers. It involves a high quality, sophisticated manufacturing process resulting in a product which can have a service life in excess of 50 years. Our Dryseal GRP roofing system is therefore very durable and can look identical to lead or copper.
“We are extremely proud that St John the Baptist Church chose Dryseal as the solution to prevent further thefts from this historic building. The church’s leaders should be saluted for fighting a 6-month battle to secure the cost-effective GRP alternative to lead, which should now be permitted for other listed churches.”
Hambleside Danelaw has campaigned for a more pragmatic approach towards GRP from the heritage and church bodies in response to the lead theft epidemic and one of its local MPs, George Hollingbery, who was recently elected to the Conservative backbench 1922 Committee, has raised the issue in the House of Commons.

Front view of Durlston Castle
Hambleside Danelaw’s Dryseal component based GRP roofing system now features on a newly restored Victorian castle that forms the gateway to a World Heritage Site in Dorset.
The grade 2 listed Durlston Castle has just received a £5.5 million facelift helped by a grant from the Heritage Lottery Fund. The contractors and architects chose Drysealfor its robust quality, compatibility with differing substrates and the ease with which intricate detailing can be formed on site. For these reasons, and because it offers an effective lead and copper alternative, Dryseal is increasingly specified for use on heritage buildings.
Hi-Tec Roof Systems, a long-standing approved installer of Dryseal across the South of England, achieved first class results with the system by forming the required detailing around the masonry abutments, on the stairways, including a spiral staircase, fall arrest system posts and achieving continuity between the roof covering and the lining of an unusual internal rainwater gutter with sundry discharge chutes.
Hi-Tec’s managing director Steve Mulcock commented:
“We have been using Dryseal for some 17 years and have never experienced a failure. We are so confident in the way that the Dryseal system deals with all of the traditionally difficult roof penetration and interface problems that we use the product whenever we have a job that requires intricacy, toughness and aesthetic appeal. We especially favour the heritage system with decorative rolls installed, to enhance the product’s appearance and to imitate lead. In the case of Durlston Castle, the Dryseal interacts with lead flashings and original stonework to create a seamless, waterproof finish”.
Andy Fell, Dryseal manager at Hambleside Danelaw, added:
“The Durlston Castle project and a recent installation on a grade 1 listed church in Bromsgrove to replace stolen lead show that specifiers like the detailed replication of appearance that Dryseal provides for heritage projects.
“Modern and versatile GRP material offers an excellent service life, strength and eventual recyclability. In comparison with other GRP systems, Dryseal is precisely manufactured under very controlled conditions to ensure a consistently high quality performance. Dryseal as a sophisticatedly manufactured and pre-cured GRP roofing system is consigning to history the ‘bucket and brush’ approach so often associated with GRP.”
Depending upon the installation, Dryseal is covered by an independent insurance backed guarantee of up to 25 years and can only be installed by Hambleside Danelaw’s approved contractors.
Zenon Rooflights
Howzat! Westfield Cricket Club bowled over with new GRP canopy
Over the years, Zenon GRP rooflights by Hambleside Danelaw have been used in an array of interesting and unusual projects, so when the company were asked how the product stood up to potential impact from cricket balls, they were intrigued.
In 2025, Westfield Cricket Club celebrate their 150th anniversary. With humble beginnings as a cricket club, with the odd game of tennis in the early years, the club diversified in 1932 and became a popular bowls venue. These days, members of the club can play friendly and league bowls, darts, and have started walking cricket sessions, all while continuing attractive cricket league fixtures for their nine senior and eleven junior teams.
Based on the outskirts of Woking, Westfield Cricket Club were successful in a bid for funding from Surrey County Council (through a scheme called ‘Your Fund Surrey’). There were several areas in need of improvement, but the main focus was on improving the artificial wicket, indoor flooring and the addition of a canopy, which is where Hambleside Danelaw’s Zenon GRP products were considered.
The club required a translucent canopy of a reasonable size, that didn’t interfere with deliveries and ground access, all while providing protection from the sun and shelter from the rain for match spectators. The canopy would also offer added benefit for when the club is hired as a venue for various celebrations/gatherings.
However, as one might expect from a cricket club, the canopy stood a good chance of being hit by the occasional cricket ball. It was therefore imperative the canopy was made from a durable material which could withstand this impact. Other alternative glazing materials were considered, and the club had several discussions with Pro Port Canopies, an established design and installation company for exterior shelters, carports and canopies, based in Staffordshire. A family run business, Pro Port Canopies has been trading for over 20 years and has achieved a variety of accreditations in that time, including ISO 9001:2015 & ISO 14001:2015 quality management, silver membership of Constructionline, CHAS Contractors Health & Safety Assessment Scheme Accredited, NHBC SAFEMARK Certified and is recognised as a Checkatrade.com preferred partner.
Rob, owner of Pro Port Canopies, said: “We always rise to the challenge of unusual customer requirements, so were very excited when Neil from Westfield Cricket Club contacted us with the canopy request. Having a long-term supplier relationship with Hambleside Danelaw meant that we knew exactly who would be able to work with us to find the perfect solution.”
Pro Port Canopies consulted with Gary Warrington, Regional Sales Manager for Zenon GRP rooflights, and discussed the options available. To help Westfield Cricket Club decide whether Hambleside Danelaw’s product was suitable, samples of Zenon Evolution LC1 were provided and the club were also shown video footage of the product under impact testing to show the superior strength when compared with traditionally reinforced rooflight sheeting products.
Neil Cheetham, Honorary Secretary stated: “We hit the sample with a cricket ball and a hammer on several occasions, and it seemed to withstand such treatment! The final costing of the canopy was more attractive than the polycarbonate roofing too!”
Gary said: “We love unusual and interesting applications for our products, and as a member of a local sports club myself, I am passionate about community facilities.”
The canopy was unveiled at their 150th anniversary celebration, which was marked with special guest, Woking MP Will Forster who presented awards, cake, and enjoyed games of bowls and cricket.
Hambleside Danelaw would like to wish the club a happy anniversary and hope for another successful 150 years!
Blade Roofing’s Successful Industrial Refurbishment in Blackheath
Blade Roofing, a national roofing company providing commercial roofing solutions across a wide variety of sectors, recently carried out a roofing and cladding refurbishment of an industrial facility in Blackheath in the West Midlands. Blade Roofing were an obvious choice due to their experience in delivering safe, efficient and effective such projects. The scope of the 2500m2 project included removal of ACM panels, installation of new Kingspan Quadcore composite and new GRP rooflights.
Refurbishment is a great way to extend a building’s service life, improve aesthetics and create a better working environment, particularly with the benefits of natural daylight being provided by new GRP rooflights as part of the overall project.
The strong relationship between Blade Roofing and Hambleside Danelaw meant Zenon GRP rooflights were an obvious choice. The assembly chosen consisted of a Zenon Evolution LC1 weather sheet. Evolution LC1 uses continuous woven glass filament reinforcement providing a product with exceptional strength, exceeding the expected performance of much heavier, thicker traditionally reinforced rooflights. The advanced manufacturing technology employed when manufacturing this product results in a lower embodied carbon than traditionally reinforced rooflights. An insulant layer of 4mm, twin wall polycarbonate provided the rooflight with a U value of 1.5W/m2K, contributing to the compliance with Part L2.
The site came with a series of challenges, not least of which being the need for the building to remain operational throughout the process. Planning and communication throughout the supply chain were of paramount importance to ensure a safe method of work with no significant disruption to the building’s occupants.
Blade Roofing successfully completed the exterior refurbishment with the same high standard of work seen across all their projects. Ben Gill Head of Contracts for Blade Roofing stated “Working with Hambleside Danelaw on this challenging project was a testament to their exceptional service attitude. Despite numerous obstacles, their expertise and dedication ensured we found effective solutions every step of the way. Their commitment to excellence truly aligns with our own, making them a reliable partner we can always depend on.”
Smurfitt Kappa – Norwich
Hambleside Danelaw recently collaborated with refurbishment specialist, Weatherproofing Advisors to provide Zenon GRP rooflights at Smurfitt Kappa in Norwich. Profiled to match their metal envelope supply chain partner, Joris Ide, the strip and re-sheet resulted in a revitalised roof enhancing the operational reliability and safety standards of the global corrugated sheet board supplier.
The Norwich hub of Smurfitt Kappa is a significant cog in their UK operations, operating 24 hours a day, seven days a week. Located on Fishergate Street in the heart of the cathedral city, it occupies an expansive footprint housing state of the art machinery and is a vital part of their enterprise. It was imperative that the location could continue operating while the roofing refurbishment was underway.
As a result of a comprehensive condition report, the 11,500m² roof was found to be well beyond its service life, resulting in severe water ingress and creating significant disruption to the operations of the building. Weatherproofing Advisors, who specialise in the maintenance and refurbishment of roofing and cladding both regionally and nationally, were involved from an early stage in the process due to their well-earned reputation for providing unparalleled levels of service.
Whilst the whole project entailed multifaceted roofing systems, the primary scope of works was to remove the existing roof and replace with a new, metal built-up system incorporating GRP rooflights; all while ensuring the factory’s operations remained uninterrupted.
The benefits of natural daylight in the built environment are well documented. During daylight hours, it is an unlimited free resource, reducing the reliance on artificial lighting. This reduces electrical energy consumption, in turn decreasing CO2 emissions and the operational carbon of the building. The building occupants also gain the health and wellbeing benefits associated with natural daylight. The diffused nature of daylight from GRP prevents glare and localised heat build-up, critical in a manufacturing environment where there may be many reflective surfaces.

This project incorporated a triple skin assembly with a weather sheet of Zenon Evolution LC1. Zenon Evolution is Hambleside Danelaw’s low carbon rooflight product. By using advanced manufacturing reinforcement technology and continuous product development, we have been able reduce the amount of resin used during manufacture compared with our traditionally reinforced Zenon Pro range. The result is a thinner, lighter product with exceptional strength that exceeds the requirements of the industry standard non-fragility testing, withstanding impacts of more than twice the force needed to pass the test. The lower resin to glass ratio also reduces the embodied carbon content when compared to traditionally reinforced products with similar performance.

Ben Orton, Service Centre Manager at Weatherproofing Advisor’s London office quoted “the excellent service levels along with a quality product are the reasons that Hambleside Danelaw continue to be a trusted member of our supply chain”.
The project has shown the effectiveness of a collaborative supply chain working well together providing Smurfit Kappa Norwich with an updated facility which will benefit from long-term security and operational stability.

When approaching the refurbishment of industrial or warehousing units; the rooflights should always be a key priority. While light levels can be increased through maintenance and cleaning; GRP rooflights typically carry a 30-year service life (with some much lower); this means that at the time of refurbishment, it is likely that the rooflights will need to be completely replaced.
Hambleside Danelaw were invited to the site of a manufacturing facility which was desperately needing a face-lift. With decades in the industry, it is rare that the Zenon team is unable to identify the rooflights, but these grime-covered single-skin barrel vaults were beyond recognition, having undergone years of weathering in rainy Preston.
Paul Hanratty, National Sales Manager for Zenon GRP Rooflights stated: “It’s very often simply not possible to determine the non-fragility status of older roof assemblies. This is also true of the rooflights installed in them. Lack of cleaning and maintenance, emissions from surrounding businesses which simply did not exist when the building was erected, poorly executed ‘repairs’, and expired design-life guarantees, can all affect the performance and status of older roofs and rooflights. A well-documented inspection and maintenance programme can help to keep rooflights performing as intended throughout their design life, saving energy and money, and safeguarding the wellbeing of anyone who needs to traffic the roof.”
‘Unusual’ is a key word in this refurbishment job – with approximately 143 runs of rooflights needing replacing, the lengths varied significantly throughout the roofscape. Positioning of these rooflights was also unusual, with some barrel vaults positions mid-slope as one would expect, and others terminating upslope at the ridge, interrupting the flashing.
BBR Roofing, the contractors for this project, removed the weathersheet to allow Hambleside Danelaw to look inside a downslope barrel vault. To their surprise, the opening revealed solid metal. The internal sheet started further upslope – despite the rooflight weathersheet beginning much further down!
Jim Bauress, Contracts Manager at BBR Roofing stated:
“We are extremely pleased with the Zenon Arc rooflights. The Zenon team provided great solutions for our specific requirements on this huge refurbishment project. The natural daylight provided by these rooflights make a real difference to the lighting within the building and creates a more effective working environment.”
The Zenon team, after scratching their heads, picked up their pencils and got to work. Due to the already existing ‘bones’ of the unit, some of the mixed bag of lengths would have to remain. It was decided that the point at which the rooflights terminated on the downslope would have to remain. However, Zenon was able to incorporate apron flashings into the design of the roofscape to allow for a more uniformity in some run lengths.
This was the largest single unit of barrel vault rooflights that Zenon have produced – 1740 linear metres, 143 runs, and days of production work. The varying lengths required a herculean effort to organise and check off. With all this in mind, Hambleside Danelaw thought it was the perfect opportunity to take to the skies.
Alongside some stunning scenery, the roof of this unit has never looked so good! And with the installation of Zenon Arc barrel vault rooflights, the occupants can expect 66% light transmission – a bit more daylight than previously.

Built to a BREEAM rating of “Excellent” and using circular economy principles, the units encompass a range of innovative features allowing future flexibility and a strong focus on the health and wellbeing of their occupants.
With the recognized health and wellbeing benefits of natural daylight in the built environment along with the ability to lower a building’s operational carbon emissions, selecting Zenon GRP rooflights by Hambleside Danelaw was an excellent choice!
Zenon Arc, a composite barrel vault rooflight solution, was specified to complement the Elite 3 SF500 system by the Euroclad Group. The triple skin rooflight assembly featured an independent in-plane liner, profiled to match the 32.200.1000 metal, and a double skin Zenon Arc manufactured using a weather sheet of Evolution LC1 for enhanced non-fragility and Service Life.
Zenon Evolution is Hambleside Danelaw’s low carbon rooflight product.

A warehouse located in Wigan was being refurbished; the existing external rooflights were replaced using Zenon Evolution LC1 external rooflights. Thanks to refurbishment contractor NSS and their client TMT Group, Zenon manager Paul Hanratty and regional manager Dave Frankland were given access to the site to complete light surveys prior to the project commencement as well as after the installation had taken place.
The warehouse is in two parts.
Section 1 is a metal clad warehouse, the existing rooflights were double skin GRP, this was the original building, dating to pre-1996. The total coverage of rooflights amounted to 10.71% of the roof area.
Section 2, also a metal clad warehouse, the existing rooflights were double skin GRP, acting as an adjoined extension to building 1 this dated to post-1996. The total coverage of rooflights amounted to 8.22% of the roof area.
Before Zenon Evolution rooflights were installed and the existing inner rooflights were cleaned, initial readings were conducted on both sections’ daylight factors. To best test the daylight factor, all internal artificial lights (with exception to emergency lighting due to health and safety) were switched off. Section 1 had a daylight factor of 1.32% and section 2’s was 1.37%.
After the work was completed, further readings were taken. As with the prior visit all artificial lights were switched off, but this time, the emergency lighting was switched off too, as it was not deemed hazardous due to the improvement in the level of natural light being filtered through the rooflights. A member of the site management team commented that he didn’t understand why the lights had been on as turning them off had made no difference; the natural daylight coming from the rooflights was such that the artificial lights were not needed.
The difference was astounding.
Section 1 now had an average daylight factor of 3.72%, an increase of 181.82%!
In section 2, however, the improvement was even more evident with the daylight factor averaging 4.12%, an increase of over 200%!
Now the two sections will be saving on energy costs due to the reduced need for artificial lights.
Zenon rooflights are designed to let natural daylight in. Used for both new builds and refurbishments, Hambleside Danelaw’s Zenon rooflights have the potential to allow three times more natural light into the interior space than a window or other vertical glazing the same size.
As members of The Rooflight Association, Hambleside Danelaw have long understood the beneficial implications of natural light and are involved in promoting best practice in relation to daylighting regulations and standards.
The Zenon Evolution rooflight is also made with significantly less resin than other products of similar performance. This is due to the unique reinforcement made of a continuous woven mesh of glass filaments. The finished rooflight is stronger, thinner, and more impact resistant than standard rooflights, going beyond the minimum requirements specified in the ACR[M]001 non-fragility test. Due to the reduction of resin required in the manufacturing process of Zenon Evolution, the finished product has lower embodied carbon.
Hambleside Danelaw are committed to sustainable construction and believe in manufacturing processes and products that are eco-friendly. In the last 10 years, Hambleside Danelaw have reduced outputs of by-product chemicals from the manufacturing process to the point where output is 75% lower than the industry standard. Additionally, 25% of the company’s total energy use comes from solar panels, showcasing our commitment to sustainable sources and renewable energy.
All Zenon rooflight sheets are manufactured and CE/UKCA marked in accordance with BS EN 1013+ A1.

Zenon helps support “break out” into sustainable solutions
In the drive to improve sustainability, Hambleside Danelaw’s Zenon brand has an unrivalled set of benefits to enable rooflights to play a bigger part in delivering an environmentally-friendly metal roofed building.
“It is human nature to stick with what we know,” observes William McDowell, National Product Development Manager- Zenon. “But, as demonstrated in the various political manifestos in the Election, the environment is figuring more highly on people’s agendas. We all therefore have to move on from the familiar, and learn about new options.”
Zenon is the only GRP rooflight that can, via an independently accredited Environmental Product Declaration (EPD), bring a tangible, quantifiable 1.5 points towards BREEAM in any new build, fit-out or refurbishment project. The points are achieved in BREEAM Materials (Mat 02) category, when Zenon is used as part of a metal roof system, and are in addition to any BREEAM points associated with the metal roof system.
High strength Zenon Evolution GRP sheets are manufactured using a mesh made from continuous glass filaments which gives greater strength than conventional GRP and, as importantly, has 40% less embodied carbon as a result. To achieve optimum performance, Hambleside Danelaw’s unique Insulator core, manufactured from cellulose acetate, delivers more light than multiwall polycarbonate for the same U value. Zenon Evolution and Insulator can attain a U value as low as 0.9W/m2K, with light transmission of around 50% and embodied carbon as low as 13 kgCO2/m2.
“The combination of Zenon Evolution GRP and Insulator core gives the optimum combination of light transmission, U value, low embodied carbon, longevity and safety available in a composite rooflight,” says William McDowell.
The product benefits are enhanced by the back-up. Zenon is the only major brand of GRP linear rooflight to offer an online configurator tool, which gives the architect and contractor the basic detail in terms of light transmission, solar gain, thermal performance and embodied carbon. Further, the Zenon support team is fast building a reputation as the best available within the market, in terms of its service, speed of response and depth of knowledge.
The benefits of the overall package are apparent in the upgrade of a 25+ years-old industrial building for international motorcycle marque Harley Davidson, by Davis Roofing. Key elements of the specification for the project was improved natural light within, and enhanced thermal performance.
Davis Roofing over-clad the outer roof skin with new Omnis Exteriors 32/167/1000 profile sheeting. Replacement of the original rooflights was achieved by site-assembled Zenon rooflights. The Hambleside Danelaw team advised Zenon Pro formed to mirror the Omnis profile created the outer layer, with a 4mm twin wall polycarbonate providing insulation between the Zenon Pro liner to the existing PMFR35 profile of the roof’s original skin. This achieved current Building Regulations, with a light transmission of 53% and U value of just 1.7W/m2K.
Joe Robbens, commercial manager at Davis Roofing explained, “The service we receive, and quality of product, from Hambleside Danelaw means we have a good relationship. Wherever possible we specify Zenon rooflights on our projects.”
Zenon Arc barrel vault rooflight used to replace old rooflights on exterior furniture manufacturer; Alexander Rose in Burgess Hill, West Sussex.
Blenheim Roofing are industrial and commercial refurbishment specialists, offering a complete design and installation service for all types of guaranteed roofing systems. They provide clients with a professional service from the initial survey to the completion of the project.
The contractors were requested by the client to survey the badly leaking roof and offer suggestions around remedial works to prevent the leaks. It was found that the aged polycarbonate barrel vault rooflights were likely to be the major culprit as the survey had shown them to be discoloured, cracked (allowing water to ingress), contain high levels of condensation and organic debris, that had entered the rooflight cavity through the cracks, building up into a sludge like substance deteriorating the rooflights further. Replacement of the rooflights was considered the best option which would remedy the water ingress whilst also improving the existing daylight and thermal performance. Zenon Arc insulated barrel vault GRP rooflights were chosen to meet the specification criteria.
Zenon Arc GRP rooflights are well suited for standing seam, curved roof applications. The rooflights were manufactured to fit a 1000mm daylight opening, with a triple skin configuration with Zenon Pro 24 weather sheet and a 40mm honeycomb Insulator™ layer.
The rooflight sheets are made from GRP which is a resin reinforced with traditional glass fibres. When natural light passes through the material it is scattered or ‘diffused’. This significantly reduces the apparent difference between light and shade and minimises the creation of shadows and glare, therefo e creating a more consistent and evenly lit space.
When incorporating the honeycomb Insulator™ core as part of a rooflight configuration, a lower U-value can be offered without significantly compromising the light transmission. Insulator™ comprises a lightweight, transparent cell structure and when light enters it is channelled directly, or by reflectance, into the building creating a better, wider spread of diffused light irrespective of the angle of incidence of
the light.
Mike Trail; Project Manager at Blenheim Roofing said, ‘We offer our clients quality solutions to give the best end result. Zenon Arc was ideal for this project and Hambleside Danelaw worked with us closely to deliver a great job to a happy customer’.
The right level of natural daylight is critically important in building where operatives need good detail perception to complete their tasks. The new rooflights will help the client to rely less on internal artificial lighting, reducing the buildings running costs.

Carried out by Hi Tec Roof Systems Ltd, the project included a flat roof refurbishment and replacement of the original northlight rooflights on an operational factory in Bournemouth.
The client’s Facilities Manager contacted Hambleside Danelaw directly after the company was recommended to replace a large area of rooflights. The existing structure was a flat roof with 32 runs of double sided northlight glazing with a flat mansard roof. The existing Georgian wire glazing was in a poor condition causing issues with water ingress and creating a hazard with potential for panels to fall into the building. It was also causing issues with glare at certain times of the day and this was intensified due to the many reflective surfaces of the internal machinery.

Amanda Davis, Hambleside Danelaw’s Southern Area Sales Manager, explained the benefits of diffused light from translucent materials like GRP and Zenon rooflights were specified to make the most efficient use of available daylight.
GRP is a thermoset material reinforced with transparent glass fibres. When natural light passes through the material, refraction occurs which scatters or ‘diffuses’ the available light and spreads it over a far greater area. This diffusion minimises the creation of shadows, glare and hot spots that other rooflight materials can cause and creates a more consistent and uniformly lit space. Samples were provided to put the proposal to the factory business’ Board of Directors and GRP was chosen as the most cost-effective and appropriate solution for the application. The project went to tender and Hi Tec Roof Systems won the contract for the full roof refurbishment. The product supplied was a factory-assembled insulated rooflight panel with the highly impact resistant Zenon Evolution as an outer sheet and a 4mm polycarbonate insulation layer. The panels were delivered over 5 phases to suit the time scale of the installation of the rooflights and the application of the flat roof. Delighted with the improved and more effective daylight and thermal performance, the client decided to proceed, ahead of schedule, with a further building on the same site to the same specification.

Hathaway completes cladding on distribution centre, as part of a new logistics park development in Corby.
Midlands Logistics is a brand new development that will encompass four distribution and logistics hubs. The park has been strategically located by the A14 in Corby, allowing access to both the East Coast Ports, and the Midlands/South East markets and neighbours a rail freight link. The development has the potential to accommodate approximately 5 million sq ft of logistics space, targeted to be complete by Autumn 2019.
After the initial groundwork was completed, the construction of the first phase started in September 2018. Hathaway were chosen by the main contractor to install the roofing system on the 844,000 sq ft building. The main contractor decided on a Euroclad Elite roof and cladding system specifying Zenon GRP rooflights. 
Hambleside Danelaw supplied 10,500m² of triple skin site assembled Zenon GRP rooflights. The specification detail included a 25 year non-fragile assembly giving a 1.3W/m²K U-value.
Rooflights were over 14.5 metres long to meet the requirements of the curved roof design.
The challenges were mainly around the production and handling of the long lengths of rooflight sheets, and the logistics involved in coordinating deliveries to ‘back load’ with used pallets. Kim Killips, Zenon Sales Co-ordinator, was in regular contact with the Hathaway’s site management team to manage this and said ‘The Hathaway contracts team were very professional, working closely with Hambleside Danelaw to co-ordinate the return of used rooflight pallets from site. That helped to cut down on site waste, maximise transport use and also allowed the pallets to be re-used, keeping costs under control’.
Hathaway’s Operations team said, ‘The project team did a great job on Midland Logistics Phase 1. The build schedule was very tight and everyone pulled together to take it over the line. One for us all to be proud of. Hambleside Danelaw played their part and delivered exactly as agreed and on schedule, keeping us informed every step of the way.’ The next phase will consist of the same metal roof and cladding system, again specifying Zenon rooflights.

New-state-of-the-art supply chain centre in Warrington for well-known pizza brand.
Located on part of a former RAF and USAAF airbase, Omega is a £1 billion project that covers 575 acres to the north of Warrington. The project encompasses commercial premises together with retail and leisure facilities and new homes. Omega’s vision is to create opportunities for business and the community. Once the Omega project is complete it is forecast that the businesses will create around 24,000 new jobs.
Part of the project in Omega South is the new £30 million supply chain centre for a well-known pizza brand, covering 10,800 square metres of the development. Providing jobs for 120 people in the local area, the centre is used for production, storage and distribution for over 400 pizza outlets across the North West of England.
The client’s requirement was for a high quality roof and cladding system. The architects on the project specified the Euroclad Elite 3 System that used on-site profile forming to achieve the long sheets required to span the entire 64m wide curved roof.
Hambleside Danelaw’s Zenon rooflights were specified to deliver high quality diffused natural daylighting into the key operational areas. Due to the very shallow roof pitch created by the central zone of curved roof, the Zenon Arc Pro barrel vault rooflight system was chosen rather than a Zenon in-plane rooflight option. Zenon Arc is manufactured from thermo-set GRP, delivering all the benefits of diffused light, high strength, longevity and fire resistance. The Zenon Arc was fixed to a kerb that followed the curvature of the roof, and is an ideal choice for low pitch standing seam systems and flat roof applications.
450 linear metres of rooflights were supplied that also included a separate rooflight liner of Zenon Pro 30 to match the Euroclad MW5 liner profile. This alone achieves Class B non-fragility when lining out the roof, and also facilitates effective sealing of the roof construction at liner level to achieve maximum airtightness, reducing air leakage heat loss and minimising condensation risk
Once the liner rooflight and kerb were installed, the pre-assembled Zenon Arc modules meant that the installation of the 1-metre wide barrel-vaulted panels could be completed extremely quickly by the expert team at IRC Carocelle. The rooflight assembly was completed with the inclusion of insulated end caps at the end of each rooflight run. Wayne Sprason; Associate Director at IRC Carocelle said ‘Installation of the rooflights was straightforward and labour saving when compared to other systems. At IRC Carocelle, we like to work quickly and efficiently to deliver a quality finished project. Zenon Arc fitted our requirements perfectly and we wouldn’t hesitate to use it again on other projects’.

A distribution centre in Wolverhampton was recently refurbished with Zenon Arc Evolution barrel vault rooflights by Roofdec Ltd.

The distribution centre project in Wolverhampton’s town centre involved a main contractor appointing Roofdec to refurbish elements of the roof according to need. One of the elements of the project was to replace the existing polycarbonate rooflights that were in excess of 25 years old suffering from damage and discolouration, and limiting the availability of natural daylighting within the building. Roofdec specified Hambleside Danelaw’s Zenon rooflights that are made from thermo-set GRP material to deliver high quality naturally diffusing daylight with improved light distribution and reduced glare. The existing metal standing seam roof system used on the distribution centre best suited the Zenon Arc modular barrel vault rooflight rather than an in-plane solution.
Supplied to fit 1000mm span, the Zenon Arc rooflights were constructed from the high strength, low carbon Zenon Evolution product incorporating the patented Insulator 20/20 system to provide a U-value of 1.6W/m²K. Zenon Arc Evolution incorporating Insulator delivers high levels of safety and improved thermal performance while retaining high levels of well diffused light transmission – all with low embodied carbon.
Other works by Roofdec included the relining of the gutters, renewing end lap seals to the main roof cladding sheets together with replacement of wall cladding prior to installing a new canopy also incorporating Zenon Arc barrel vault rooflights. Overall the works took 12 weeks to complete.
John Barnes, Managing Director of Roofdec said ‘Everything went well in replacing the old rooflights and we would look to use the Zenon Arc barrel vault rooflight system on similar projects in the future’.

High Access Maintenance Limited undertook a 16 week project in Warrington on a distribution centre to refurbish the building and its roof.
High Access offer a comprehensive high-level building maintenance and cleaning service for the commercial sector with their head office based in Greater Manchester. From here and their other branches in Scotland and in Slough, they undertake both emergency and planned projects nationally.
This project involved a 8-12 person team over a period of 16 weeks, and included:
- Supply and installation of safety netting and 1400lm of edge protection with 2no Haki stair towers
- Replacement of existing rooflights using GRP Evolution LC1 Class 3; 140 runs at 22m in length
- Grinding off all cut edge corrosion to all roof sheet laps
- Application of mastic and basecoat to the full roof – circa 8000m²
- Clearance of all guttering to low and high level roof areas and sealing of all gutter joints
- Thorough cleaning of all roof sheets
- MEWPs provided to accommodate all works safely
For the replacement of the 25+ year old outer sheet, the decision was to upgrade to the superior strength Zenon Evolution LC1. Unlike traditional GRP rooflights that are reinforced with short rovings, Evolution is formed using a continuous filament woven mesh of glass fibres providing very high tensile strength and resistance to tearing. This goes way beyond the minimum requirements for non-fragility. Due to the nature of the material this also means less resin is required within the manufacturing process compared to traditional reinforcement techniques, resulting in a significant reduction in embodied carbon in the finished product with no loss in performance.
Phil Seaton; Operations Director of High Access said “The rooflights were delivered promptly and competitively priced. I was pleasantly surprised on the quick lead time, which enabled us to complete the programme of works a week early. The impact on the natural daylight internally is substantial. Both client and landlord are thrilled with the results”.

Blade Roofing completes refurbishment in Croydon.
Blade Roofing are a national business specialising in reactive and planned roofing services using their own fleet of powered access equipment. They undertake a variety of refurbishment projects in slating and tiling, built-up felt, sheeting and cladding, singly-ply membranes, liquid applied coatings and a variety of dilapidation remediation specifications. They have two offices located in Bradford and Essex.
The refurbishment project included Zenon Arc; the modular GRP barrel vaulted The rooflight system. A 1200mm daylight opening with 8 runs of 60.4 metres was required. The rooflights specified and supplied were double skin Zenon Arc Pro type delivering a U-value of 2.9W/m²K, 66% light transmission and 66% total solar transmission. Due to the nature of the GRP material used the rooflights offer excellent diffused light, reducing glare and minimising the creation of shadows throughout the building.
Rob Bland, Managing Director of Blade Roofing said “we were invited to tender via referral from a Quantity Surveyor that we’d worked with before at another company. We won the tender and completed the project within a tight time frame due to the busy vehicle repair centre below”.

After
He continued to say “safety was paramount and we worked closely with the client to install safety netting and scaffolding in a narrow time frame to work around their busy schedule. Having a straightforward install was critical given the time allowed and we were very pleased to use the Hambleside Danelaw product.”
Natural daylight has been well documented as being beneficial in respect to health and well being, safety, productivity and energy savings within industrial buildings.
Rob summarised his teams experience of the Zenon Arc system saying “the back office gave us all excellent support to ensure that the install went smoothly. Our installers also found the rooflights exceptionally easy to fit”.

Bott Group is a world-leading manufacturer and supplier of workshop equipment, in-vehicle equipment and workplace systems. From design and manufacture to supply and installation, Bott has a strong reputation for high product quality, service excellence and value for money.
Their factory in Bude, Cornwall has a 9,400sq. metre roof incorporating 780sq. metres of rooflights. Alto Roofing & Cladding replaced the existing discoloured rooflight outer skins with Hambleside’s 2.44kg GRP Zenon Pro rooflights, which resulted in improving the spread of natural daylight and making Bott’s workplace a more sustainable, energy efficient and enjoyable place to work.
Peter Houghton of Alto Roofing & Cladding commented “We have now replaced all rooflights to this building which was done in two phases totalling approx. 780sq.metres. I know that the customer made a large saving on electricity due to less artificial lighting after we completed the first phase.”
At Hambleside Danelaw we manufacture rooflights which help create green buildings through the use of natural daylight. For further information on this and how we can advise on your daylight strategy please contact our sales team on 01327 701920 or email sales@hambleside-danelaw.co.uk
Since the opening of their first UK store in 1972, Wickes continues to expand its trading base. The opening of their new premises at Baildon Holmes Mills (a site that was home to British Mohair Spinners for more than 240 years) will add to the already exceeded 200 store milestone.
When it comes to the environment, Wickes are taking positive steps to improve energy efficiency in their stores whilst making a concerted effort to source materials from environmentally responsible suppliers and manufacturers. Wickes specified Hambleside Danelaw’s Zenon Factory Assembled Insulated Rooflights (FAIRs) to give the best possible thermal performance whilst at the same time enhancing the spread of natural daylight into their buildings thus making the interior of the building a much more pleasant environment for Wickes colleagues and customers alike.
Steelwork purlin centres on the buildings frame were designed at 2.45 metre centres. Using conventional products, this would have needed very thick, rigid FAIRS to accommodate the span without significant cosmetic ‘sagging’, or additional steelwork to reduce the span condition at the rooflights, which would have resulted in significant cost increases. The new Zenon Multi-Liner on the revamped Hambleside Danelaw FAIRS allowed the panels to accommodate the 2.45 metre purlin span without the need for additional costly works or materials. This specification also included Hambleside Danelaw’s ZSL50 side tapes for improved thermal performance and increased airtightness at the rooflight side laps together with a Zenon Evolution high strength external skin which is the best solution for environmentally conscious or commercial buildings as it uses less resin in the manufacturing process, is thinner, lighter and with less embodied carbon. Other benefits include a better profile definition to suit the surrounding metal sheets, more reliable sealing and a non-fragility performance which equals or betters that of heavier conventionally reinforced products.
The store’s 1,800m² warehouse roof area consists of 120mm thick Tata Trisomet 333 composite panels coated in HPS200 Ultra, 15% of which is made up of Hambleside Danelaw’s rooflights achieving a low U-value of 0.8W/m²K whilst retaining improved light transmission levels close to 60% better and a total embodied carbon value of 13.36kg CO2e/m², more than 60% less than that of a similar traditional rooflight specification.
Project team
The project was designed by Beckwith Design Associates and built by Marshalls Building Contractors Ltd with Zenon rooflights fitted by Temban Roofing Ltd.
The new store at Cyfarthfa Retail Park in Merthyr Tydfil is the first eco-learning store for B&Q and hosts a number of innovative eco-friendly features including an ecologically diverse plant rich green roof. The 55,000 sq. ft. flagship store opened last autumn with developer Hammerson and B&Q working collaboratively to achieve low energy, low carbon and high recycled targets. This resulted in the project winning the Sustainability Achievement Award at Property Awards 2015.
The standard of the store’s environmental performance is 50% better than the industry benchmark (2010 Part L), achieving a Band A Energy Performance Certificate rating, a BREEAM rating of ‘good’ and a 23% reduction in embodied energy relative to industry bench mark standards for similar retail developments.
Hambleside Danelaw’s low carbon rooflight – Zenon Evolution, was specified for this project by B&Q due to meeting the safety, durability, sustainability and life expectancy objectives of the client coupled with a significant carbon reduction saving. Zenon Evolution offers the best solution for environmentally conscious buildings as it uses less resin in the manufacturing process, is thinner, lighter and with less embodied carbon. Other benefits include a better profile definition to suit the surrounding metal sheets, more reliable sealing and a non-fragility performance which equals or betters that of heavier conventionally reinforced products.
The store includes a 45,000 sq. ft. warehouse and a 10,000 sq. ft. garden centre incorporating rooflights to 15% of the roof area achieving a U-value of 1.3W/m²K. For the extensive areas of green roof, the specification called for rooflight openings above the surrounding vegetation, and here Zenon Archlight barrel vault rooflights were installed on site constructed kerb systems. For the remaining areas of roof, in-plane Zenon GRP rooflights were supplied to match the profile of the cladding system.
Dave Humphrey, Design Manager for BAM Construction commented “The Hambleside Danelaw rooflights were simple to integrate into the design of the congested roof on B&Q Merthyr Tydfil. They provide excellent light transmittance values and allowed us to maximise the natural light from the limited amount of area available to us. They were installed into two different types of roofing products – Steel & Aluminium with a Green Roof over. They play an important part of the overall Sustainability Award from Property Week.”
This project was developed by Hammerson, designed by Powell Dobson Architects and built by BAM Construct UK with Zenon Evolution rooflights fitted by roofing contractor ABS Elbrow as part of a Euroclad building envelope system.

The new site encompasses a filling and production hall and a containers inward building. It will halve AkzoNobel’s environmental impact in the North-East, reducing energy consumption per litre of paint produced by 60%. This will be achieved by employing cutting-edge manufacturing technology and the latest in building design.
Hambleside Danelaw’s eco-friendly, factory assembled rooflights were chosen by contractors Hathaway Roofing.The roof consists of Tata Steel Trisomet panels which consists of 796m2 of rooflights, manufactured to match, using high performance Triple Skin at 120mm depth. This included 40mm Insulator and a Zenon Evolution external skin.
Insulator and Zenon Evolution were ideal for AkzoNobel’s environmental needs. Insulator reduces carbon emissions without decreasing light transmission and gives enhanced light diffusion. By maximising the use of natural daylight, the need for artificial light is reduced and energy costs are lowered. Zenon Evolution products are manufactured from high grade glass reinforced materials which reduces the amount of resin required in production, with the result that the embodied carbon element is reduced.
Terry Minns, of Hathaway roofing commented, “Hambleside Danelaw’s product was fully compliant with the specification from the architects. After vetting the product we decided that Hambleside Danelaw produced the best solution. Everything went smoothly and we will definitely be using Hambleside Danelaw again in the future.”
Liebherr Sunderland Cranes Ltd. is a company of huge importance to the city of Sunderland, both as a local employer and an international supplier and exporter. At the beginning of 2013, Liebherr announced plans to extend the Wearside site and refurbish the 30 year old production hall. Hambleside Danelaw’s Zenon Evolution wall lights have been selected to replace the existing wall lights which have become heavily engrained with dirt over the years, making the production hall a dark place to work.
The production hall is an HH Robertson’s metal profile building envelope and is based on the south bank of the River Wear. It is a very tall building – approximately 30m high and, due to the location, strong winds can cause high levels of wind suction. It was therefore specified that the replacement wall lights must have excellent structural strength without compromising translucency. Easyseal UK, the main contractor promoted Hambleside Danelaw Zenon Evolution wall lights as they are exceptionally strong, despite being thinner than the average wall lights. The thinner, low resin content of the wall lights reduces the embodied carbon and makes them easier to install and seal within a metal profile building. At fire grade SAA0, these wall lights possess the highest level of fire retardancy to meet specific fire performance requirements.
16 vertical runs of wall lights needed replacing, along with the main 50m horizontal run which spans the length of the building. Ronnie Thirlwell, Director of Easyseal UK commented, “We have dealt with Hambleside Danelaw in the past and have always received a service that is second to none. The brief itself was simple – improve the light quality in the factory. The Zenon Evolution wall lights were ideal for the project. There were some concerns in identifying the profile as it is such an old building, but Paul Hanratty and Vince Cranmer were on hand to provide superb technical backup and attended site several times to ensure everything was going smoothly. We have had tremendous feedback from Liebherr and have been asked to quote for the installation of further wall lights on the other side of the factory.”
Michael Sharman, Processes Administrator who is based at the Liebherr Sunderland site said, “The new wall lights have made a huge difference to the working environment. Even on a day that’s dreary, it is still bright in the factory.” It is clear that the replacement wall lights have made a big impact on the Sunderland team.
The B&Q warehouse situated at Bridgend had seen better days and was badly in need of refurbishment. The interior was suffering from severe water ingress from the dilapidated, leaking roof and employee and customer safety was at risk where pools of water were forming in wet weather conditions. The natural light into the building was hindered due to the aged rooflights being covered in moss and fungi, and being tarnished due to years of weathering. This meant the warehouse required artificial light, adding to the energy consumption of the building. The lack of insulation in the roof also added to energy running costs.
Hambleside Danelaw were specified for this project by B&Q due to our environmentally positive approach to business and we worked alongside B&Q’s approved contractors, Group Tegula. The original roof, consisting of fibre cement sheets, remained in place to act as the liner panel for this over-roof project. The aged and failing rooflights were removed and new Zenon Pro liner panels were installed in their place. A metal spacer system was then installed to create a cavity of 80mm depth and the roof was completed with profiled metal cladding and weather sheets. The cavity was insulated with mineral wool to further improve the U value of the building.
The new roofing system and rooflights have transformed a once fragile roof into one that is non-fragile and has improved the thermal performance of the building envelope. The heat retention and the increased natural daylight through the rooflights have also reduced the energy running costs. Dave Murray of Group Tegula commented, “This project has vastly improved the overall experience of visiting the store. The building is now warm and dry and well lit by natural light rather than artificial lighting, giving a much better environment for customers and staff.”
Based at the Advanced Manufacturing Park in Rotherham is the new Rolls Royce Advanced Blade Casting Facility. Currently under construction, the facility is expected to produce its first blades in late 2014, with the capability of manufacturing 100,000 aerospace blades per year when fully operational.
Designed by Bond Bryan Partnership in Sheffield, the building has a 13,000m2 metal standing seam roofing system supplied by Euroclad. Hambleside Danelaw’s triple skin barrel vaulted rooflights were selected for the project as they are ideal for standing seam system roofs.
The triple skin rooflights are comprised of Zenon Evolution liner panels which are manufactured from high grade glass reinforced materials. This reduces the amount of resin required in their production, considerably improving their strength and reducing the embodied carbon. The outer Archlight weather sheets make up the curved layers, which are placed on an upstand that curves to the roof. These 100m long barrel vault rooflights have been applied downslope from the ridge and continue down to the eaves. This minimises the number of metal/translucent junctions and eliminates rooflight end laps to improve reliability and servicing.
The U value of the rooflights is calculated at 1.7W/m2k which indicates high levels of insulation and complies with European Standards. The liner panels meet the highest fire grade of SAA0, higher than the typical requirement for liner panels in a double skin assembly. The Archlight weather sheets are grade SAA. Robert Baines of Northern Cladding, who were contracted to the project by BAM Construction, commented, “The technical specification for the fire performance of the rooflights was a big driver for choosing Hambleside Danelaw’s product. As the structure of the roof was standing seam, the barrel vaulted rooflight option fitted perfectly. BAM Construction who are the main contractors have said they are delighted with the result.”
People respond better to working in natural light conditions, benefitting their own performance, and less dependency upon artificial light reduces energy consumption and costs as well as impacting upon the building’s overall carbon footprint. Rolls Royce will benefit greatly from the installation of these rooflights.
Survey Roofing of Whyteleafe, Surrey, are carrying out replacement works at Scottish and Southern Energy, Peterhead Power Station. Vertical wall lights are being replaced with Hambleside Danelaw’s Zenon Evolution profiled sheets in natural translucent, with SAA Class 1 fire rating.
The sheets are manufactured in the UK using our Zenon Evolution bi-axial glass mat. The added strength gained by the structure of the glass allows us to use less resin in production, and therefore lowers the embodied carbon, without reducing the performance.
The vertical wall lights installed at Peterhead have been profiled on our continuous profiling production line to match BSC LR1000W. This order has been fulfilled in a heavier weight, 3.26kg/m2 rather than the standard 2.59kg/m2, due to the specification requirement to cope with the extreme weather conditions on the exposed coastline and nature of the building use. The project is still ongoing.
A new generation of gyms utilising refurbished industrial buildings are appearing across the North. The state of the art gym in Leeds, Xercise4less, is very pleased to offer its customers natural light levels to workout in, rarely needing artificial lighting, due to the performance of the Hambleside Danelaw rooflights that were installed as part of the refurbishment.
The GRP fibreglass rooflights have been manufactured to special order in our Inverness factory, to match the Big 6 metal profile with a 40mm box for increased thermal performance. These factory assembled double skin rooflights comprise 2.44kg/m2 Zenon Pro top sheet and a 1.83kg/m2 Zenon Pro liner panel.































































The difference was astounding.
