A combination of product quality, technical support, and aesthetic appeal has seen Marley’s Acme Double Camber Clay Plain Tiles specified for a major roof replacement project at Stoke Minster school in Stoke-on-Trent.

The Host Helix building, also known as the “Helter-Skelter,” was a unique and striking structure built in 2011 with stunning views of North London and Wembley Stadium. Over time, the building experienced general wear and tear and water began to enter the buildings’ complex structure.Polyroof Products were called in to consult with the clients and offer a seamless, encapsulated solution that could address the many unusual details associated with the building’s design.The SolutionA full survey of the roof terrace areas was conducted by the Polyroof Technical Services, after which a bespoke specification was produced for the works. The proposal document detailed a comprehensive set of recommendations for producing a seamless solution to encapsulate the problematic roof, therefore solving the issues that had arisen over the years due to its condition and age, as well as the issues associated with the original design of the pitched, curved roof.Polyroof SA Carrier Layer was then applied over the cement particle boards with Polyroof pre-formed GRP Drip Trims fixed to the external edge. For continuity and to create a uniform finish, the SA Carrier Layer was extended onto the main roof sections as a substrate for the Protec system.Any details requiring local reinforcement were treated with Protec Resin and 75mm wide Polymat 450. The curing process was allowed to take place. To accommodate structural expansion / contraction movements at appropriate details, 25mm disbondment tape was installed prior to local reinforcements.The first coat of Protec Resin and Polymat 450 was applied at a minimum coverage rate of 1.3 – 1.5Litres/m² (0.66 – 0.77m²/Litre) and was allowed to cure. To complete the system, a second coat of Protec Resin was applied at a minimum coverage rate of 0.5Litres/m² (2.0m²/Litre) and was allowed to cure.ComplexitySuch an iconic building in the local community, the client wanted to protect the original aspects of the building to the fullest extent, so the Protec system installed at the perimeter was color-matched to the original blue and grey colours. This was achieved by blending pigments until they matched the desired colors, in turn the pigment was then blended into the Protec resin before application. The survey revealed concerns about the original building designs from 2011 and the roof’s drainage system. Due to the roof’s pitch, rainwater was cascading down the curved slopes at high velocity and causing water to bounce into the building under the original capping.After many discussions between the main contractor and Polyroof, as well as the provider of the external cladding, it was agreed that the perimeter detail needed to be encapsulated with the new waterproofing system to prevent further water ingress. Fire-retardant cement particle boards were fixed to the internal and top faces of the external parapet walls, and the Polyroof SA Carrier Layer was applied over them with Polyroof pre-formed GRP Drip Trims fixed to the external edge.The Protec System was then applied to encapsulate the entire parapet detail, meaning its waterproof integrity would be covered under the Polyroof Guarantee. The curvature of the building added complexity to this process, and the contractor took great care in cutting the trims to size and fixing them to the external edge to ensure they followed the profile of the structure. Due to the building’s height, all the trims were face-fixed to prevent wind uplift.WorkmanshipIn order to improve drainage and prevent water from accumulating in hotspot areas of the roof, the contractors were instructed to install new internal curved gutter channels at the point where the roof and building met. These channels were designed to have a sufficient height and angle to effectively direct rainwater towards the outlets, preventing water from pooling on the roof. However, the installation process was made more complex due to the curved nature of the building’s architecture, which required careful measurement and customization of the gutter channels to fit the unique shape of the building.Additionally, the contractors had to consider the many joins of the gutters and how they would hold up to the elements over time as the building structure expands, contracts and moves. Extra steps were taken to ensure the gutters liquid membrane was properly sealed and secured to prevent leaks.The contractors were instructed to repair all protrusion and mansafe post details as necessary in order to allow the Protec System to be installed to a minimum height of 150mm, and to terminate it underneath a suitable weathering flange or jubilee clip. In addition, all right angles were to be reinforced with double taping. Any protrusions that were liable to significant movement was required to have disbondment i.e., bond break, tape applied to it to stop the external coating from stressing on expansion. Furthermore, all pipes were to be abraded, solvent wiped, and where necessary, primed in accordance with the Polyroof coatings manual. A flashing detail was also to be created with a weathering flange or seal.All outlets were inspected to ensure that they were functioning properly. Any outlets that were deemed unsuitable were replaced with new ones. The outlets were cleaned, prepared, and primed as necessary. The Protec system was then dressed into the outlets as far as was practical. The inspection and replacement of the outlets and the preparation of the Protec system helped to ensure that the drainage system functioned effectively.ConclusionThe refurbishment of the roof was completed within the client’s target timeframe and budget. Following a final inspection by Polyroof Technical Services, which highlighted quality workmanship of Tower Asphalt Ltd, the client received Polyroof’s trusted Accredited System Guarantee and now has the peace of mind the roof will be leak-free for decades to come.

The new six storey HSBC building at No.1 Charter Square in Sheffield utilises ABG’s blueroof system to meet the National Planning Policy Framework and the site's Flood Risk Management Policy. Attenuation for the building is provided at roof and street level, comprising void formers constructed within the roof and streel level structures to temporarily attenuate storm water, before gradually releasing it over a number of hours via the ABG restrictor chambers.At street level the system was installed underneath the surrounding walkways and access routes to restrict discharge rates at ground level, including a large landscaped podium deck area above a service yard where heavy duty void formers were used in the event emergency vehicle access is required.

FOAMGLAS® Tapered T4+ (Slab)Design Architects: Renzo Piano Building WorkshopExecutive Architects: Adamson Associates, LondonMain Contractor: Mace; Roofing Contractor AC PLCConstruction: 2012Application: Warm Roof - FOAMGLAS® Tapered T4+ (Slab )Finish: Bitumen membranesFOAMGLAS® provided the ultimate solution for the roof maintenance platform of The Shard at level 75.Its light-weight and high compressive strength enable regular maintenance to be carried out without risk of surface damage.At 310 m, Shard Tower is one of Western Europe’s tallest buildings; exposed to extremes of temperature & the revolutionary structure sways up to 50 cm in high winds.The building maintenance platform on level 75 islocated directly above the viewing galleries, and essentially forms the Shard’s roof. To shed water, the flat metal platform required an insulation with a tapered top surface.In this extremely exposed location, and with significantloads upon the platform, a truly reliable solution was needed. FOAMGLAS® insulation combines compressive strength, long-term insulation performance.Using their "in house" CAD systems, FOAMGLAS® designed a bespoke Tapered Insulation system. Taking full advantage of its low coefficient of expansion, and to eliminate thermal bridging, FOAMGLAS® and its membranes were adhesive bonded onto the metal structure. The unique ability of FOAMGLAS® to withstand high compressive loads ensures regular maintenance work can be safely carried out without damage to the insulation or the membranes.Adamson Architects commented on this project: "FOAMGLAS® has proved itself to be the ultimate solution for the difficult loadbearing areas of the Shard. Specifying cellular glass insulation ensured complete integrity and performance in key areas of the Shard Tower".

Whitburn Partnership Centre was designed by Project Architects, Matthew Fair, Neil Forrester and Jamie Bateman at Smith Scott Mullan Associates for West Lothian Council. The design of the contemporary £4M building restores the historic Whitburn Burgh Hall original façade as it is one of the towns most renowned buildings and incorporates a new-build two-storey extension.Located in the centre of Whitburn, this building is a community hub that embraces the West Lothian Council’s model of bringing together services that benefit local communities whilst delivering financial efficiencies through the decrease of council buildings. This building facilitates a library, community halls, museum and customer information service office, making it an important community resource. Project:Whitburn Partnership CentreProject type:New buildLocation:West Lothian, Scotland,Waterproofing:Bauder Total Roof System (BTRS)Roof size: 525m2Energy generated from PV array: 10.35kWp Specifier: Smith Scott Mullan AssociatesMain Contractor: Maxi ConstructionApproved contractor: ProCladd (Scotland) LimitedSolar PV installer: Intelligent Electrical SolutionsThe specificationTo support the West Lothian Council's sustainability objectives of achieving high energy efficiency, it was our responsibility to specify a waterproofing system and provide a solution for natural energy generation. The bituminous Bauder Total Roof System (BTRS) was chosen for this project as it features membranes that can withstand impact and tearing, as well as thermal insulation that met the required U-value of 0.15 W/m²K. This waterproofing system is verified by the BBA and offers a service life in excess of 35 years.The BauderSOLAR system was also specified, as it incorporates photovoltaic arrays for natural energy generation. The photovoltaic mounting system is attached to the roof without penetration of waterproofing or the deck, safeguarding the integrity of the waterproofing to fulfil its full-service life.Project challengesThe Architect’s design incorporated unusually high parapet upstands, which posed a challenge for installers. Area technical manager for Bauder, Christopher Langton, attended design meetings with the Architects and Main Contractor to discuss the best solution for installation. A mutual agreement was made for the underlayer to be mechanically fixed to prevent any slippage of the capping sheet membrane. Due to the height of the upstand, non-combustible insulation BauderROCK was incorporated into the design at these details.The installation of BauderSOLAR F uses prefabricated bituminous BauderK5K membrane sleeves to slip over the mounting plates and welded into position, anchoring the plates to the surface of the Bauder waterproofing system. Approved BauderSOLAR installers, Intelligent Electrical Solutions, installed the BauderSOLAR system, collaborating with ProCladd, approved contractor for the waterproofing installation, and other trades during the roof installation.There is a junction where the flat roof meets the original slate roof of the adjacent building, this detail fell under the torch free zone that hot air welding techniques are used to install the membranes within these areas.The resultInstallation of the Bauder waterproofing system may only be carried out by trained and certified operatives approved by Bauder. A project pre-start meeting was held by Bauder site technician, Duncan Hastings, and area technical manager, Christopher Langton inviting the Site Manager from Procladd and their Bauder badged operatives. During this meeting, they discussed the installation of the project, and identified the areas that required torch-free and torch-safe detailing. They also discussed how the project was going to be delivered in co-ordination with other trades working on the site at the same time, for example cladding and lead that was installed atop the waterproofing upstand details.Weekly site-inspections were carried out by Bauder site technician, Duncan Hastings during the project. Visiting the site frequently meant that Duncan could provide consistent support to the installers and answer any questions they may have had directly. It also meant that the quality of the roof installation was being monitored regularly to ensure it would be to a high standard, achieving the comprehensive guarantee.The approach taken to deliver this project on time and to budget was through meticulous planning and working to tight time frames. The organisation of the delivery of Bauder products to site had to be in line with the schedule to ensure that the site was ready to receive a delivery. With the project located in the busy centre of Whitburn next to a cross junction with traffic lights. This meant that timed delivery of products to site was required in addition to prebooked off-loading by pump truck and tail lift or by telehandler.Health, safety and environment was managed during the planning, design and installation of this project by advising that all installers follow the advice shown in the “Responsible Specification Checklist” produced by the National Federation of Roofing Contractors.In accordance with the Workplace (Health, Safety and Welfare) Regulations 1992, roof edge protection in the form of scaffolding was installed during installation. The project’s perimeters were surrounded by Heras fencing to isolate the construction site from the public. All scaffolds that were on the elevation next to the public had toe boarding and safety mesh where required.As standard, there was a one-hour Firewatch after the Bauder membranes have been installed using a gas torch. This was carried out by Procladd operatives each day when they were working on the project to ensure the welfare of the workforce, and the safety of other trades and that of the building. The 19kg gas cylinders were used on this project as they are easily transportable on the roof area. At the end of each working day, the cylinders were stored in a locked and designated gas storage unit on site.System installedBauder Total Roof System (BTRS)1 BauderK5KElastomeric bitumen torch-on capping sheet in charcoal grey.

This project for Durham Lane Primary School saw the refurbishment of their existing roof. The previous bitumen waterproofing was showing signs of wear. Isolated areas of leaks had started to form, which was presenting classroom disruption.ChallengesFor funding purposes, the roof area was inspected and separated into two phases. Phase 1 of the roofing works presented a number of potential fire risks with combustible substrates and penetrations. The existing make-up performed poorly when tested against current building regulations.SolutionsFollowing minor remedial works, the existing waterproofing system was inspected and deemed suitable for use as the air and vapour control layer. Thermal and acoustic upgrades were introduced through the installation of Hytherm MW mineral wool insulation, ensuring building regulation compliance and an acoustically sound teaching environment in compliance with BB93.To complete the installation, Hyranger reinforced bitumen waterproofing system was installed, achieving a 20 year insured guaranteecovering waterproofing system materials supplied by Axter. In accordance with the NFRC’s Safe2Torch guidance, cold applied liquid waterproofing was required for detailing to fire risk areas; in this instance, Starcoat R was the system of choice due to uniform aesthetical finish and cost efficiency.Systems in useHyranger®Starcoat® R

ChallengeKalzip were tasked, alongside contractors Lakesmere, to develop a roofing structure that would be vital to the overall appearance of the building and one that would fulfil the stringent acoustic criteria – whilst working to tight deadlines.SolutionFollowing extensive testing, Knauf Insulation Rocksilk® RS45 product in 50mm and 75mm were specified within the 40,000m2 Kalzip System in the AluPlusPatina finish.Heathrow’s new Terminal 2, also known as The Queen’s Terminal, boasts exceptional architectural design and is 40% more carbon efficient than the previous building. Kalzip’s large waveform roof bestows one of the iconic features of the terminal.A multi-layer approach was taken when it came to installing Knauf Insulation Rocksilk® RS45. By layering the insulation products in different densities across the Kalzip standing seam roof, rigorous sound absorption and sound transmission measures were met, whilst retaining the form and functionality required by the designers.As a robust, resilient and dense Rock Mineral Wool insulation slab, Knauf Insulation Rocksilk® RS45 has excellent acoustic properties that help to reduce the impact of airborne and rain impact noise. It also has an excellent thermal conductivity of 0.035W/mK, helping to provide passengers with a comfortable environment.

The challenge was to construct a roof top extension on top of the luxury hotel NOBU in Shoreditch. The plan was to add an additional 1 storey of hotel rooms, suites, dining areas and open terraces that would replace the existing planted roof. The chosen solution was Tarmac Toplight C lightweight structural concrete in a pump mix with the addition of steel fibres, ensuring maximum weight loss of 35% with no compromise on structural concrete performance.By adding steel fibres into the lightweight mix the composite metal deck system could be installed without the need for traditional expensive and slow steel reinforcement across the deck. The use of lightweight concrete, furthermore, reduced the load by 35% which meant the existing structure did not need to be reinforced or under pinned. The construction programme time was also reduced considerably.

VELUX Glazing Panels bring daylight to an 18th century Cornish jail to support the transformation into a luxury hotelAll that was left of the powerful-looking Victorian Bodmin Jail in Cornwall, was a ruin without a roof, with vegetation slowly taking over. In 2015, Mallino Development appointed the services of Twelve Architects to undertake an impressive redevelopment project of the jail and turn it into a modern and aesthetically quite different hotel. To deliver the modern comforts hotel guests expect during their stay and the thermal efficiency required for sustainable operation of the hotel, a holistic system using VELUX Glazing Panels was designed. It took 214 VELUX Glazing Panels, formerly known as Vitral A98 Glazing, to recapture the original roof lighting sitting above the two historic wings.For more information, read the full case study

The award winning Noah’s Ark Children’s Hospice currently supports over 160 children who are seriously unwell, 230 of their siblings and 350 of their parents/guardians by providing holistic, bespoke care. To facilitate the care of even more children and their families and care givers, a new building was needed. Main build partners, 8build, undertake one charitable build project every year and were therefore recommended for the Ark project. Their unique collaborative approach and utilisation of supply chain relationships kept project costs low with these costs savings directly benefitting the hospice as they could then be spent on care for the children. The project won the "Roof Gardens/ Living Wall Installations - Commercial Roof Garden or Podium Landscaping - Under £500k" award in the BALI National Landscape Awards 2020.

This reimagined building in Fitzrovia, which puts people, wellness, and sustainability first, is another project we are particularly proud of and here’s why.The Met Building is 12 storeys high and one of a few such examples in London’s West End. Its design was inspired by one of New York’s landmark buildings, Lever House, one of Manhattan’s leading examples, which inspired decades of US corporate architecture.While the building’s interiors are crafted to appeal to corporates and creatives, the Tower has been designed to put people first, offering breathtaking views across London, and focusing on efficiency and productivity.The whole roof terrace of the Met Building’s Podium was built over the top of the existing roof and on a huge network of steels that are designed to direct the load away from the roof below.The system used on the roof terrace is our TerraSmart® Rail Paving System finished in our Porcelain Paving Range. This system features super-strong, 100% recyclable aluminium joists, overlapping to create a lattice framework that delivers maximum support for the porcelain paving above. In addition to complementing the overall aesthetics of the entire project, the system is fully non-combustible (Class A1 fire-rated) and, as such, in perfect harmony with the focus on the wellness and safety of all the building’s occupants. The porcelain pavers were inspired by nature and feature the performance of high-quality ceramics and environmentally conscious manufacturing that aligns with the project’s focus on sustainability.And to top it all, the entire solution installed is backed by our RYNO® IGNO® 30-year system warranty and 60-year design life.In total, the RYNO® TerraSmart® Rail Paving System was installed on 3 terraces at the Met Building, all built on the existing steel frame, and the planters that add to the outdoor experience have been integrated into the design and placed directly on top of the RYNO paving system.We are proud to have collaborated very closely with Vert Projects (the Main Contractor) and The Landscape Partnership (the Landscape Architect) in delivering this great design.

Battersea Dogs and Cats Home in London, the best-known animal sanctuary in the world, is currently undergoing the biggest development in its 154-year history - a £5 million scheme delivered by main contractor, Sir Robert McAlpine. The development will bring the charity’s existing buildings and facilities into the 21st century and will include a new build, state of the art veterinary hospital which will be protected by an innovative new waterproof membrane – Cold Melt® from Proteus – a seamless application designed to work in harmony with the roof infrastructure and so tough that it has been BBA certified to last for the lifetime of the building.Quality Control An integral part of this transformation is the built up roofing system of 1,200 square metres of Cold Melt®. Applied by the Proteus Licenced Contractor, a 5 layer built up system was employed to offer a bespoke specification tailored to the client’s needs and budget.The built up system consisted of a layer of Cold Melt® Proteus’ own innovative, cold-applied liquid membrane, over which an insulation layer of Proteus Pro-Therm XPS was laid. The Licenced Contractor then added a separator sheet of Proteus Low-K followed by an attenuation mat and then three different finishes in three different areas of the roof – paving slabs, a green roof and decking.Health & Safety Proteus’ liquid applied systems are cold installed and therefore negate all the elements of fire risk when working in confined spaces. Of particular importance was the low odour that Cold Melt® exhibits, meeting all the health and safety criteria necessary to protect both the Licenced Contractor’s operatives and the dogs and cats home’s residents.Long term performance Cold Melt® incorporates recycled rubber-crumb and other organically grown products and when covered, creates an elastomeric, seamless and cold applied membrane which has a life expectancy longer that the design life of the building on which it is installed.

ChallengeContractors Guaranteed Asphalt (GA) faced a unique conundrum regarding the insulation of the roof of the O2 Arena, the centre piece on the site of the former Millennium Dome and the first purpose-built music venue in London since The Royal Albert Hall in 1871.As the area required superior acoustic properties, a rock mineral wool product was the obvious solution, however the split-level roof form of the construction meant that loose mineral wool fibres were visible in the surrounding airspace. This is where Knauf Insulation’s technical expertise became invaluable! Knauf Insulation was able to specify a bespoke white-tissue-faced Krimpact product which entrapped the loose fibres.SolutionKnauf Insulation supplied over 100 tonnes of their Rocksilk® Flat Roof Slab Extra at 150mm (2x75mm), a consistent, high density rock slab with superior impact and compression resistance. This material is designed to offer not only the acoustic performance required by such a venue, but also good thermal resistance and an excellent fire rating classification (Euroclass A1 non-combustible, the highest level possible). The white-tissue-faced product was suitable to be exposed to the elements, and later sprayed with a grey solar reflective paint to seal the surface and enable the product to camouflage into its environment.To make the project even more complicated, the cranes used in the production did not fit under the existing structure of the Dome which meant that the roof had to be constructed at ground level and lifted into its final position. This was no problem for Knauf Insulation thanks to its innovative Supakube delivery system, which meant the product could be delivered to the correct area of the project with minimum effort. Supakube uses advanced compression technology and strong packaging materials, which ensures the product is not only easy to store but can be delivered more efficiently saving time and reducing carbon emissions from delivery vehicles as more product can be loaded onto each lorry.

OverviewKEA Dublin is a 2787m² shopping centre in Ballymun Ireland which required a full smoke ventilation system from Powrmatic.Project BackgroundIKEA Dublin is 30,000 square-foot shopping centre in Ballymun Ireland which required a full smoke ventilation system from Powrmatic.Project SolutionPowrmatic supplied 73 Roof Opensky smoke ventilators to the new IKEA store in Dublin. Specified and installed by Air Design Systems Ltd, the installation is providing full smoke ventilation to five separate areas within the store.The second area is the show room and café which were naturally ventilated by louvred ventilators and split into zones using a fixed smoke curtain. A similar approach was taken with the self-serve warehouse and checkout area, which was also naturally ventilated using louvred ventilators and fixed smoke curtains. Polycarbonate blades are used on the louvred ventilators to allow natural light to enter the spaces. Additionally, the escape staircases were ventilated using louvred ventilators at the head of the stairs and a local control panel with an emergency break glass.Project Result“We were involved from the very early in the design stages of the project, using our knowledge and experience of installations within other IKEA stores and warehouses to engineer a suitable, cost-effective solution,” recalled  Air Design Systems Ltd Director Alan Clare.“Within these works we have had to include for three separate main control panels, all electrical wiring run in fire-protected cable, local control panels with emergency break glasses and a mimic control panel linking all smoke ventilation zones. We also provided rain sensors, roof access hatches, and head of lift shaft cowls,” he added.Due to the success of the project, there was a requirement within a year of opening to extend the warehouse area. Air Design Systems Ltd was awarded the sub-contract to extend the system into the new space and link back to the existing control system. In total, a further 14 Powrmatic ventilators were installed in the warehouse roof & walls and at the head of the two additional emergency staircases.Powrmatic’s Roof Opensky ventilators are attractive, low-profile units that have been specifically designed for both smoke and heat exhaust and natural ventilation applications. The Opensky can be roof or wall mounted for exhaust or inlet and can be supplied with a hinged base for use as an access hatch. They are tested for use as smoke ventilators to BS EN 12101-2.

Project: Creative Centre, York St John UniversityClient: Tate+Co ArchitectsScope of project: Design and supply 24 bespoke-sized rooflights for the roof of a triple-height atrium to fit within apertures in a glulam timber grid.Products: 24 bespoke sized em.glaze rooflights, some with concealed actuator smoke ventsThe ChallengeThe roof of the striking 14m, triple-height atrium, which forms the centrepiece of the newly opened Creative Centre at York St John University, features a glulam timber roof grid. Architects Tate+Co wanted to punctuate that grid with bespoke sized rooflights to bring even more light into a space which is used as an exhibition, teaching and theatre space, as well as somewhere for students to mix and relax. The rooflights had to have a sleek, minimalist aesthetic, in line with the overall design intent of the atrium and, because almost all the services in the atrium are hidden, needed to be available with matching concealed actuator smoke vents.The SolutionWhitesales designed and supplied 24 bespoke-sized em.glaze rooflights which suited the specification perfectly. The flush-glazed glass-to-edge design of the em.glaze units with flat sealed glass units fitted within a fully welded, thermally broken aluminium frame achieved the lean, crisp look the architects were looking for. The fact that they were also available with fully concealed actuators in the smoke vents supplied by our affiliate business Sertus was an added bonus. All the rooflights were supplied for the project complete with preformed 300mm PVC splayed upstands, which enabled them to be fitted directly into the glulam grid, saving the contractors time on site. They were also fitted with specially coated glazing which allowed for a degree of solar gain and contributing to the low energy requirements of the BREEAM Excellent rated building.‍The BenefitsAs well as the meeting the design specification, Whitesales’ technical team helped to ensure that the em.glaze rooflights could be installed quickly and efficiently by the main contractors Kier Construction. We estimate that our recommendation to supply the units with preformed 300mm PVC splayed upstands saved the roofing team at least two weeks on site because they didn’t have to construct the upstands themselves and the integrated splay made waterproofing the roof a lot easier. Tate+Co Director Andy Baker-Falkner is delighted with the em.glaze units: “We liked the lean, crisp design of the Whitesales em.glaze units, particularly with the clean white reveal and option for fully concealed vent actuators.”
