"green roof"

This community engagement project for YMCA in Milton Keynes featured Wallbarn M-Tray on a roof space which acted as a leisure and social area for the students and residents of the YMCA campus in Milton Keynes. It also featured in the training and development of young people with learning difficulties and with challenging upbringings to learn about construction and green roofing, being able to gain NVQ qualification and further certification for installing green roofs.The green roof will be moved in its entirety to a new premises in early 2022 where the benefits of the M-Tray system are fully demonstrated. Rather than have to dig up tonnes of loose aggregate, established sedum and wildflower planting and sheet drainage materials; each module can be simply lifted up and transported via pallets to the its new home the other side of Milton Keynes at the new YMCA building. As this new premises will house many of the young people using YMCA services, this new green roof becomes their green roof to enjoy.

This project had incredibly restricted access, where the client wanted a green roof on an existing bitumen rooftop overlooked by hotel rooms. The M-Trays® had to be transported on a trolley through the hotel kitchens. They were winched onto the roof itself using a genie lift and slotted into position in a matter of hours. Trying to construct a roll-out green roof was impossible, given the restricted access. Installation was fast and effective, taking only a day and giving an instant green roof. M-Tray® dramatically improved the view from the rooms and improved the guests’ experience.

This project involved the construction of a Data Centre just outside Dublin, with a focus on incorporating a green roof. MOY collaborated with the client, their design team, the main contractor, and the roofing installer to execute the roof installation for an extensive green roof. The green roof utilized MOY's Paraflex FM Global approved Warm Roof System, featuring Paratherm T 120mm insulation board and an anti-root cap sheet. The final touch included the installation of a sedum blanket grown in Ireland, containing native Irish sedum species registered in the national biodiversity database, creating a durable and vibrant living roof.

The client desired a green roof at the back of this beautiful family home. Access was very restricted. The speed and ease of transporting and installing our modular trays meant minimum disruption for the homeowner. Trays were delivered to site on pallets and handballed to the roof. The modules were laid down onto a geotextile fabric. Pebbles were then laid around the perimeter between the trays and any outlets to provide the required firebreak. Vegetation blended quickly creating a seamless green roof and, looking out from the upper floors, a sense of continuity from the house across the garden.

This project involved a brand new Starbucks drive-thru being built in West London where the customer wanted the overlooked rooftop to be green. The customer was able to give the basic dimensions to our team and describe how they wanted the roof laid out. We then calculated the exact quantity of units needed with our inhouse software and gave delivery and installation guidance to the contractor and end client. Wallbarn also supplied the materials for the semi-extensive border including geotextile fleece, drainage board and our specially-developed substrate for a comprehensive green roof solution,

The client contacted us in urgent need of a green roof solution before a project handover. Green roof was part of the planning application. Pre-grown panels with patented design were delivered on pallets and lifted to the roof via forklift. The ingenious connecting system means each module clicks to its neighbour tightly and securely so once installed, the sedum has a seamless appearance. The plants are a mixture of sedum species ideal for the UK climate. They are well rooted into Wallbarn's bespoke substrate and fully mature. 250 sqm of green roof was installed in 1 day.

Our client was a major nursery stock grower in British Columbia with a very large sedum green roof project in Vancouver. The architect was concerned about future-proofing the green roof and wanted to ensure that, if ever they had issues with their waterproofing seal or any other aspect of the structure, the green roof could be taken up without too much disruption. It was decided that a modular solution would be the best route. M-Tray® was included in a worldwide competition to find the most suitable modular design and was judged as the best product available.

New school construction with biosolar wildflower roof system. Selection of sedum and native wildflower species pre-planted into M-Tray modular green roof trays for fast and easy access to and installation on single ply roof membrane. Client increased thermal insulation, reduced rainwater run-off, achieved energy savings, protected the waterproofing membrane and attracted wildlife to the roof space.The wildflower / PV roof system will feature in students' learning projects in the future.

A good example of the before and after effects of laying a sedum roof garden and accompanying deck and paved area onto a small domestic roof terrace. All these products are designed to sit on top of the waterproof membrane (in this case single ply) there was no issue of damage to the roof. The support pads lifted the decking off the roof, eliminating the risk of the timber piercing the membrane, and drainage was maintained through the roof surface since the green roof system has a cavity beneath its own reservoir and drainage layer to allow water run-off.

Mayfair, London Our modular green roof solution, the M-Tray®, has transformed what was previously a fairly unsightly bitumen rooftop at a Mayfair hotel into a beautiful green space for guests to enjoy. Conversion of the 13sqm space was awarded to Wallbarn after we successfully completed the hotel group’s first green roof project at the Radisson Heathrow. Being so easy to transport our M-Trays®were selected as the fastest and most efficient way of converting the unused space into a lush, green and aesthetically-pleasing space. The installation only took half a day with minimal disturbance to guests.

Green innovation was at the forefront of designs for a stunning, award-winning family home created at Manaton, in the heart of secluded Dartmoor. Rhepanol hg was selected for the three distinctive green roofs that help to shape the character of the large, four bedroom Devon property, which incorporates a raft of measures to minimise its environmental impact.

Silverlakes eco village in Dorset is a new build venture where the client wanted to achieve maximum sustainability.The houses, boat houses, garages and also communal areas such as the leisure centre required green roofs and M-Tray® was chosen due to its ease of transport and installation, and its square modular nature. Pre-grown, healthy sedum plants inside the plastic trays were laid onto the flat roofs across the village, providing an attractive dressing and improving storm water attenuation, thermal insulation and a magnet for wildlife.

Boughton’s Intensive green roof substrate has been successfully trialled in a ground-breaking analysis project at Coventry University assessing the feasibility of ‘greening’ landscapes with ecological beneficial habitats.  With the objective being to research the benefits and plausibility of incorporating green space and wildlife-friendly habitats into heavily built-up areas, Coventry University handpicked Boughton’s Intensive IN1 substrate based on its nutrient content, weight, and the inclusion of a water supply in chambers beneath the sub-base.The majority of green roofs in the UK fall into the ‘extensive’ category and are based on a low growing succulent, Sedum, which only requires a few centimetres of substrate to grow, whilst intensive green roofs provide a deeper soil depth and can support a more complex plant system. To this end, Coventry University wanted to explore the advantages of intensive green roofs, which offer greater biodiversity, often create accessible spaces, and offer the best insulation properties and storm water management. The organisation partnered with SEL Environmental, who provided its intelligent water management systems for the project.Boughton’s Intensive IN1 substrate boasts greater organic content than extensive substrates, meaning it supports larger plants and can be installed at greater depths, varying from 100-500cm. IN1 provides a stable growing medium for wide variety of plants in intensive green roof installations, including green roof lawns, shrubs and trees.Depending on the substrate depth and plant type, permanent irrigation systems (above or below ground) are sometimes installed with this substrate to as a backup for extended dry periods. They are not required for everyday irrigation, as the substrate has the ability to hold onto sufficient moisture during ambient conditions. The project, funded by Knowledge Transfer Partnership (KTP) and headed up by Sophie Barron-West, followed plant growth for four years from 2017, with a break due to Covid 19. Dr Stephen Coupe and Dr Liz Trenchard from the University’s Centre for Agroecology, Water and Resilience (CAWR) offered their research expertise.CAWR’s Dr Stephen Coupe says: “The technical requirements of Boughton IN1 were a big part of why we chose it. We also wanted the chance to get as many wildflowers in the space as possible. The nutrient levels were perfect because it wasn’t too rich. In fact, it was a ‘just right’ formulation that wasn’t going to overstimulate but would also deliver enough nutrients for what we needed. Ultimately it was going to be perfect for long-term sustainable plant growth.”He continues: “Reliability was another consideration because we knew we could get it delivered on site on time and, because of Boughton’s location in Kettering, we weren’t concerned about lead times, so that was a plus. It’s safe to say it was a studied choice.”Ground-breaking resultsAccording to the University, the trial resulted in ground-breaking analysis into how different types of green roofs can be created and maintained, as well as what their benefits would be alongside others in a built-up area.  The project successfully demonstrated the ecological impact of placing retrofit green roofs onto existing infrastructure, even with a focus on wildflower species and a relatively short development time. An independently-conducted ecological survey recorded five insect species that have national and local rarity value, including two species of bee that are deemed ‘nationally scarce’ and ‘nationally rare’. Of 457 preserved specimens taken on the green roofs at Coventry University, a total of 120 different insect species were recorded, including wasps, sawflies, hoverflies, beetles, and as many as 11 species of bee.  Coventry University’s findings revealed that the innovation in green roofs has improved and increased the total constructed habitat for rare insects. Research has also enabled better water management alongside habitat enhancement. This research has been incorporated into SEL’s product range, where green roofs are now used across four sites in Coventry, London, Aylesford and Blackburn. CAWR’s Dr Stephen Coupe said: “Ecology, biodiversity and wildlife are largely forgotten by planners, designers and builders in developments. Most green roofs installed in the UK are based on sedum, and, while there are additional features that can be added to these green roofs to improve biodiversity, they are rarely incorporated. Our findings, using Boughton’s Intensive green roof substrate, are that the retrofit of green roofs is feasible and, more than four years into development, IN1 has supported verifiably diverse green roofs. The plants on these roofs supported several insects that have rarity status in the UK, which is very positive.” Dr Coupe adds: “Whilst it is probable that substrates take many years to develop anything like the maturity comparable to natural soil, after just four years, IN1 went from having no recordable eukaryotes, to a concentration of organisms, including worms, soil mites and rotifers.”  Boughton Business Development Manager, Jason Lock comments: “Boughton was delighted to be part of this groundbreaking project and buoyed by such positive findings. Our products have been used successfully in a number of iconic green roof developments around the country over the years but it was a pleasure to be involved in such an important trial that would deliver verifiable results assessing the potential for green roofs to create new habitats in urban environments and enhancing local ecological diversity. Boughton offers an extensive range of green roof substrates and we welcome any research that helps further innovation around the application of green roofs.” The experiment at Coventry University is ongoing and the team are set to feed back again at the end of the summer about how prolonged dry weather has affected results. Dr Coupe says: “The beauty of this project is that there is no general timeline for a piece of green space. We need funding to support our ongoing investigations but there are options and opportunities for long-term research. It can last for the lifespan of the site and I think we will see really interesting developments. There is no reason why, over time, these green spaces would be indistinguishable from an existing habitat.” Boughton’s portfolio of green roof substrates are specifically engineered for different types of roof greening, both for domestic and commercial projects. A full product specification is available for each of Boughton’s Green Roof Substrates, and other landscaping products, making exact specification simple and straightforward. There’s also a section on each product listed online, titled ‘to specify (copy & paste)’, designed to make your job even easier. To enquire about your next project, contact Boughton by calling (01536) 510515 or email sales@boughton.co.uk.

The challenge was to incorporate a green roof finish both flat and curved to the roof areas. The roof pitch being as steep as 45 degrees in places, a pitch not conducive with a green roof system. ABG used their expertise in green roof and slope stabilisation to make the curved green roof possible. The system incorporated a series of anchor points, reinforcement geogrid (Trigrid), and geocellular technology (Erosaweb) to retain growing medium on each roof. The Green Roof system incorporates a SMART rain sensor and automated irrigation pipe system with each finger haveving its own dedicated mains operated tank

Raithwaite Hall is a 5 star, 45 bed boutique hotel set in 85 acres of wooded valleys within the North Yorkshire Moors National Park. The hotel offers terraced views of the landscape and across the Whitby coastline. A new extension was designed that is built against the hillside with stepped landscaped areas around the new building and an intensive green roof terrace to help blend the structure in with the surrounding gardens.The intensive green roof terrace is installed directly above a new function and dining room and required a specialised design to accommodate the additional loading and provide the necessary drainage for the turf lawn.     By utilising a multi-purpose geocomposite roof drainage board, the green roof system could be achieved to meet the project specific requirements. The ABG Deckdrain 2540S-NW20XUV product offers a lightweight option that delivers the equivalent drainage capacity of 300mm of drainage stone in a 25mm layer that weighs over a 100 times less per square metre. The lightweight drainage layer is supplied in rolls and is fast to install and move into position. The Deckdrain layer includes an integrated filter geotextile bonded to the top of the cuspated core. This prevents the growing media layer from intruding into the drainage void and filters the soil to prevent clogging. The Deckdrain is made from a high strength HDPE core that supports the 200mm deep layer of growing media required for the intensive green roof installation with deeper root systems. The underside of the product is impermeable and provides additional protection to the liquid waterproofing membrane. A green roof surface finish further helps to prolong the lifespan of the waterproofing layer and prevent UV degradation. The large grassed area on the podium also reduces surface water run-off and the grass is protected against waterlogging via the efficient drainage board layer. The shallow drainage build-up required also reduces the height of the steps onto the terrace and the associated cost of stone flags. The completed installation encompasses a 20mm Roofdrain drainage & reservoir board to support a secondary smaller sedum roof area, as well as Deckdrain layers installed for structural drainage to the surfaces around the patio slab and retaining wall areas.ABG provided a full green roof project design, installation and maintenance service for the project.

This project involved a high-rise office being refurbished. Being in the Central London and nearing completion meant a busy site. Ultra fast and mess-free installation was essential. M-Tray®’s were delivered to site on pallets and quickly unloaded. The M-Tray®’s stackable design meant it was easy to transport through the (finished) building and elevator. The individual trays were then carried up the final flight of stairs to the rooftop. As the trays simply clip together they are quick and easy to install. In just 4 hours a the roof space was transformed into a green roof.

Green roofing forms a key part of roof design as part of a model for sustainable living in 21st century London. Barking Riverside is a joint venture project between Bellway Homes and the Homes & Community Agency. It is an element of the Mayor of London’s plan to build 10,800 new homes, retail, transport links and new town facilities in the Barking region of East London.

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.

When developing new buildings, it is always important to consider the environmental impact. Responsible sourcing of materials is high on every priority list, along with reducing waste to landfill. But what about the local impact, such as the effects on local wildlife? A living roof/green roof system, such as the one installed by the Premier Contractor at Seaford Head Golf Club, is a very clear example of the steps that can be taken towards reducing this impact and providing an alternative space for wildlife to inhabit. A warm roof system was installed onto a structural plywood deck, after which a vapour barrier and insulation boards were mechanically fastened to provide both thermal efficiency and air leakage control. After the underlying installation had been suitably restrained in accordance with a site-specific wind uplift calculation, the roof membrane was mechanically fastened to complete the waterproofing system. Our PVC roof membranes have been tested and can be utilised without the need for additional root prevention barriers (test standard EN 13948), and because PVC is extremely lightweight, they are the perfect choice for these applications, reducing pressure on the underlying structure. In conjunction with our Living Roof/Green Roof specialists, a site-specific living roof system was supplied and installed over the completed waterproofing.Waterproofing System:DANOSA Single Ply 1.5mm - AnthraciteConstruction Type:New BuildWarm RoofSector:LeisureApprox.

Despite the challenges posed by completing construction and opening during the first lockdown, the new Skelton Lake Motorway Services project opened in March 2020 as planned, providing essential services to hauliers and key workers travelling during the start of the pandemic. The project incorporates an extensive green roof build-up to minimise the visual and physical impacts of the development on the surrounding country park and to enhance the biodiversity of the project.The wildflower green roof design provides multiple environmental benefits; including provision of a new habitat for local insect and bird life, helping to lower the site’s carbon emissions by absorbing heat emitted from the building into the cooler roof surface - reducing the air conditioning demand in the summer months. The green roof build-up also provides a level of insulation against heat loss in winter. 

The Strathmore Centre is an important educational facility in Teddington, West London. Soprema supplied the roofing products for this new building, working closely with single-ply specialist Rock Roofing, main contractor LIFE Build Solutions and green roof partner SkyGarden to achieve a stunning result. Steve Hatcher, Contracts Manager at Rock Roofing, greatly appreciates the reassurance that, “once you’ve installed a Soprema product, you know you have delivered top quality.”SOPREMA FLAGON PVCThe roof build-up for the Strathmore Centre project consisted of a FLAGON PVC single ply membrane with a Wildflower Blanket System from SkyGarden on top. Steve points out that, especially in this kind of scenario, the reliability of the waterproofing is key: “Soprema’s single-ply is not only easy and quick to install, it is also highly reputable. When installing a product beneath a green roof, you need to have the confidence that that product will work. That’s the reason we choose to partner with Soprema.”CLOSE COLLABORATION ON THE DESIGNRock Roofing, LIFE Build, SkyGarden and Soprema collaborated closely on some last minute changes to the specification and the design.INSTALLATION TYPEOriginally, the team at Rock Roofing had proposed a mechanically fixed roof system. Yet on-site checks revealed that a loose-laid system would be a better match for the concrete beam construction of roof. Moreover, the latter installation method would be quicker.Steve and his team checked with Soprema to ensure that the proposed change would be covered by the guarantee, and with SkyGarden to ensure that the green roof met the minimum weight requirements. “Once we got confirmation from all the parties involved, we moved forward with the new installation type”, Steve explains. “We always get good technical back-up from Soprema, making for a very easy process, even when lastminute adaptations are required.”PARAPET CAPPINGMoreover, Rock Roofing came up with a value-engineered alternative for the capping on the parapets that were supposed to be done by a third party. Steve: “We gave the main contractor an alternative parapet detail, which would speed up installation and result in significant cost savings. We proposed a smaller capping and consulted with the team at Soprema to make sure the new perimeter detail was in agreement with them, which it was.” Thus, Rock Roofing saved LIFE Build considerable time and money.A BEAUTIFUL GREEN ROOFSteve looks back with satisfaction. “We had no complications or issues and even won back some of the lost time”, he recaps. LIFE Build is very pleased with the result as well. Steve: “We got some great feedback from them. Even though they think the green roof looks amazing, they pointed out that, in a way it’s a shame it covers such a nice roof. That’s a beautiful compliment.”QUESTIONS?

The Green Roofs Consultancy report looked to the provision of Green Bio diverse roof to address the need to encourage additional species. The ABG Green Bio diverse Roof System includes a mixture of plug planted sedum, cuttings and seeded annual and perennial wildflowers. ABG Roofdrain was used as a reservoir and drainage base layer to optimise water retention and prevent ponding. Special provisions were made to create hibernicula for local endangered species. The roof will benefit the building by providing additional insulation and reducing noise pollution.The roofs substrate filters out dust and pollutants helping improve the environment nearby

The new generation of M-Tray® modules were used on this office building in Poklington, Yorkshire. This project was in the heart of the Vale of Yorkshire, within and Area of Outstanding Natural Beauty and planning sensitivities dictated a green roof was needed on the office building. The clients wanted the existing farm buildings, which had been converted into offices and storage space, to blend into the hillside with the structures having the very lowest impact on the surrounding countryside.The timber framed building meant a low weight solution was required so the 100mm deep pre-grown modules were ideal.

A new car park has been constructed near the Hornschuchpromenade in Fürth and covered with an extensive green roof system. The car park has capacity for 380 cars and has been designed by The Max Bögl Group (MBG) with ease of construction, cost efficiency, visual impact and low maintenance in mind. In collaboration with contractors Isobautec, they selected MobiRoof green roof system from Mobilane as the most suitable option to cover the 1300 square metre roof expanse.

In the Peak District National Park with views of Cressbrook Dale and the Monsal trail, a thermal bridging solution developed by Owens Corning FOAMGLAS® is helping to deliver high levels of thermal performance for a new, modern home with a minimal space heating demand.The Quarry is a mostly single storey, green-roofed dwelling set on the site of a former shallow stone quarry. Working with John Pardey Architects (JPA), client Will Griffiths secured permission for a modern design faced with traditional materials to ensure a development that sits comfortably within the landscape.

The Protec System was used to waterproof the domed green roof areas of this striking, sustainable house development which was featured on Chanel 4’s Grand Designs. With an ambitious vision and a tight budget, Robert and Milla Gaukroger set about transforming a dated 1980’s house overlooking Lake Windermere into a state-of-the-art, eco-conscious home. Since the house lay in beautiful hillside surroundings, in order to blend into this setting, the domed roofs of the house were to be covered with a wildflower meadow mix to provide a green roof construction.The SolutionThe Protec System was chosen as a waterproofing membrane for the roofs as it is ideally suited for green roof applications. Lightweight, flexible and highly durable, the system can easily accommodate structural expansion movements and is tough enough to resist root penetration. The Protec system was applied to over 350m2 of domed roof to provide a long-lasting waterproofing membrane.The key reasons why Eastleigh chose Protec are the same reasons that has seen it become one of the fastest growing cold-applied liquid roofing systems in both the new build and refurbishment markets. Combined with the timber cladding to the verticals of the building, the finished aesthetics of the development blended seamlessly with the surrounding areas.A warm roof build-up that can be made waterproof at multiple stages:For larger projects the Protec system can be made temporarily waterproof at two stages prior to the application of the full waterproofing system. The first stage is upon installation of the sealed, aluminium-faced vapour barrier.The second phase follows the reinforcing of the foil-faced insulation board joints with Protec resin and taping mat. This enables a much more controlled approach to the installation with a greatly reduced chance of rain causing disruption and damage during the works.Highly flexible membrane:Regardless of the size of the roof, Protec forms a homegenous membrane, without a single joint or seam and without the need for any expansion joints.RapidCure technology for quick installation:The application of Protec as a liquid, through to the curing process where a solid, tough membrane that can be walked over, takes only 30 – 60 minutes. This enables large sections of the roof to be fully completed in a short space of time.Installing the Roofing SystemsThe Protec System provided waterproofing to all flat roof areas as well as the extensive parapet wall sections. The roof areas were made up of two designs: the Protec Warm Roof System (approx 7,500m2) and Protec applied to concrete as part of an inverted roof design (approx 1,000m2).The roof installation was carried out with a planned, phased approach that was synchronised to the wider construction schedule. For the warm roof areas, the first stage was to fill the troughs of the structural metal roof deck with acoustic insulation infills that will dampen external noise within the leisure centre. Next, the crowns of the deck were primed ready to receive the self-adhesive vapour barrier.The use of a high-performance aluminium vapour barrier not only eliminates the risk of condensation within the roof, but also provides temporary waterproofing protection, which is extremely useful on larger works such as this.The Polyroof RES Insulation boards, which comprised of a two layer system totalling 170mm to achieve a U-Value of 0.14 W/m2K, were bonded using high-performance PU adhesive to the vapour barrier. Following the wind uplift calculations it was determined that mechanical fixings were not required for this application – making for an extremely rapid installation. As you can probably imagine, fixing through 170mm of insulation into the crowns of the metal deck can be a tricky and time-consuming task.A key advantage of using a tongue and groove insulation system is that the finished surface of the roof is smooth and level without any unsightly board steps that can also lead to standing water issues. The insulation board joints were sealed using Protec resin with Polymat Taping Mat 450 which, in addition to providing additional strength to the joints, also creates a temporarily waterproof layer.For the inverted roof sections, Protec was applied directly to the primed concrete/screed surface. The membrane was inspected by Polyroof Technical Services, signed off and then covered with inverted roof components. An interesting fact when using Protec in inverted roof situations is its incredible durability performance – as tested by the BBA, Protec “can provide an effective barrier to the transmission of liquid water and water vapour for the design life of the roof in which it is incorporated”.Monitoring and CompletionThroughout the duration of the contract, Polyroof Technical Services carried out regular site visits that were reported back to Interserve as part of Polyroof’s free-of-charge contract monitoring service. This enabled the client to keep up-to-date with the progress of the roof installation in detail and also provided peace of mind that the original specification was being closely followed and implemented.Polyroof worked closely with the Roofline Group during the installation, enabling the challenges were identified and solved in an efficient and coordinated manner – saving the client time and money.

A residential customer had a storage unit and wanted improve it by adding a green roof. M-Tray®, being modular in shape and easy to install, was the perfect solution. The green roof had to be walked through the house to access the garden. Traditional roll-out green roofs, with their loose substrate bags and loose sedum blankets were too messy to transport indoors. M-Tray® is self-contained within the walls of the plastic tray and comes with fully established, sustainable vegetation. M-Trays® clip together easily, allowing the sedum to blend together, providing a beautiful, seamless finish.

Under the pitched roof, the gable end glazing has been designed to perfectly match the profiles of the SUNFLEX SF75 bifold doors, whilst the inclusion of a single access door allows the extension to angle away to create a larger kitchen/dining area.

Scotland’s Largest Single Office Building with Rooftop Running Track and 360 Panorama.A Sustainable and Futureproof Roof, Harnessing the Power of the OutdoorsBothwell Street in Glasgow is now home to an exceptionally progressive office space – making way fora new chapter in the rich history of the area. If there are any doubts about what Grade A office spacereally means, then think touchless entry, bike storerooms, lux changing facilities, an 8,000 sq. ft roofterrace, a 150-metre rooftop running track, 4 activity zones/terrace spaces and panoramic views.The project complements the sustainable regeneration programme along the Clyde Waterfront also,home to the new financial Northern European hub, firmly cementing the business district at the heart ofmodern Glasgow.GOALSThe architects at Sheppard Robson have made sure sustainability and lifecycle credentials remaincentral to the design specification. Occupants’ wellbeing has been carefully considered with a stunningpanoramic rooftop and 150m running track and general outdoor employee wellness facilities.A roofing solution was required to support the lifecycle of the building along with an excellentproduct reputation for this distinguished office space. Given the quality, longevity and environmentalconsiderations required from the roofing design, the insulation properties and warranty performancewere extremely important from the outset.CHALLENGESOur Technical department assisted the architectural and construction teams to resolve numerouscomplex design elements across the varied roof zones including running track, ballast walkways, greenzones, and pedestal zones, to determine the best roofing solution.Installation of the Davit Arm System for a building of this scale was especially important so personnel canbe safely suspended whilst working at height. This presented us with a unique challenge in providing aworkable solution that aligned with the sequence of works, whilst facilitating future routine inspection ofits base plates, and maintaining waterproof integrity without compression.Careful planning and detailing were required around roof penetrations to minimise aesthetical impact,and roof equipment was safely installed above the roof assembly.SOLUTIONThe construction comprises a composite concrete slab receiving our Hot Melt Hydrotech Waterproofing System. Offering a true lifecycle – Hydrotech high performance waterproofing, through its’ unique characteristics and installation process, now forms part of the building fabric. The result offers complete watertightness for the lifetime of the building.The building is also insulated to a high u-value target offering exceptional thermal performance and achieving a high kPa rating. This was essential to receive loadings from all components including overlying finishes, roof equipment and the end use for the building occupants.Key fire performance standards were achieved throughout including the lift overrun and lower roof terrace areas where the preferred solution was switched to our Derbigum sustainable warm roof system to maintain project performance targets.LIFECYCLE MANAGEMENTDesigned with BREEAM credentials and an EPC rating coming in at below 10 the careful focus on lifecycleconsiderations and the choice of materials throughout the building envelope is exemplary.Hydrotech hot melt is a high-performance solution containing 30% recycled content and zero productfailures in over 50 years, offering lifetime peace of mind, designed for the service life of the roof.PROJECT DATACompletion: Autumn 2022Building Type: Commercial OfficeProduct Application: Hydrotech & Derbigum waterproofing systemsCertification: BBA Approved, European Technical Approval & FM Global Class 1Architect: Sheppard RobsonMain Contractor: HFD Group

A three year construction project in Knightsbridge required a temporary green roof on welfare huts. The local residents were concerned about overlooking these steel huts long-term. The solution is M-Tray® – our modular green roof system. The steel huts were wheeled into position on site on skates. They were covered with an EPDM waterproofing membrane. M-Tray® units were installed. They were easily carried up the stairs by hand and installed by hand within minutes. The modular and portable M-Tray® can just be unclicked and lifted away upon completion of the construction process.

Brand New Oasis Academy, Silvertown Leads Education Facilities by a Mile with Garden Roof Spaces, and Rooftop Sports Pitch In the heart of what is now the Royal Docklands, a former industrial zone south of Royal Victoria Dock lies a brand new carefully considered Academy. Set to serve 600 students in this emerging community, the “superblock” thrusts modern educational facilities well into the 21st century. Despite the constrained site, the building design harmoniously incorporates vantage points from outdoor social spaces at varying levels.There’s no need to worry about a gravelly all weather pitch causing havoc at your hockey match. There’s a state-of-the-art full size Multi-Use Games Area, lush planted external roof spaces, a double height sports hall, and main hall/performance area making up the core of the building inside.CLIENT BRIEF AND DESIGNRenowned in their field, regeneration experts Morgan Sindall required a single sourced end-to-end roofing solution that could deliver a full system specification underpinned by a 35-year system warranty, installation expertise and site management.Understanding the Architect’s vision at award winning Rivington Street Studio to create a transformative educational haven and maximise the potential of the outdoor roof areas helped the Alumasc Roofing team bring this roof to life.PARTNERSHIPWorking with the project teams across Morgan Sindall, Rivington Street Studio and Fenland Flat Roofing pushing the boundaries and setting the standard for the future of the built environment in the Education sector.Tim Mott, Senior Design Manager, Morgan Sindall, “Brian and the Alumasc team have been on-site with additional safety constraints and delivered high-quality regular progress reporting to achieve the deadlines for the students to move in next year and really put these fantastic facilities to use.”Brian Cottington, New Build Regional Manager - South East & London, “The original specification included warm roof build ups which utilised tapered insulation, however this was subsequently adapted and working closely together with the Architect, Morgan Sindall and Fenland Flat Roofing we implemented a universal standard build up using an inverted system, with less complexity whilst achieving the high system performance and BRoof (t4).”Richard Trew, Associate, Rivington Street Studio, “The garden roof areas and outdoor space bring this building to life and against the industrial backdrop create a nurturing school environment. It was great working with the Alumasc team solving problems and overcoming design challenges along the way.”Chris Preston, Estimator, Fenland Flat Roofing, “Working closely with the local Alumasc Roofing Site Technicians and engaging in extensive discussions agreeing the final system requirements meant the installation process ran smoothly.”ENVIRONMENTALLY FOCUSSED SOLUTIONThe high performance Hydrotech inverted roof is a special formulation of refined asphalts and synthetic rubbers with 30% recycled content. Installing insulation with exceptional thermal properties including 300mm extruded polystyrene insulation and 56mm inverted upstand insulation effectively reduces heat loss.SAFETY PERFORMANCEThe application is a one-component, hot-applied, fully reinforced, flexible, self-healing hot melt monolithic membrane, applied in a liquid state to the substrate giving a 100% absolute and seamless bond.The Academy has a 35-year warranty for the works and has a fire classification of BRoof (t4) in accordance with BS EN 13501-5.ABOUTThe Oasis Academy is set to open its doors February 2022.
