Over 2,300m² of Protan SE 1.2mm PVC single-ply membrane was installed in the Protan Prefabricated roof system at Wilmslow Garden Centre, Cheshire. The main driver behind the installation of this roof system was the time constraint placed upon the roofing contractor for installation of the roof. Using Protan's unique ProPlan CAD software, a bespoke solution was created for the project - prefabricated rolls of membrane measuring 3.96x8.00m were manufactured to span the barrels of the roof. This minimised on-site waste and reduced on-site hot air welding by 1,080 linear metres.

For its architecturally striking Orwell House scheme in Bethnal Green, London, Bell Phillips Architects (BPA) has specified hand-formed, multi-coloured Antro bricks from Vandersanden, the brick maker renowned for its innovation, craftsmanship and sustainable manufacturing practices. Antro provides just the right balance of colour, texture and contrast for this affordable housing project, designed by BPA for London Borough of Tower Hamlets and forming part of the Berthold Lubetkin-designed Dorset Estate, originally constructed in the 1950’s and 1960’s.Comprising 20 flats in total, Orwell House is a new, wedge-shape, in-fill development, just off Colombia Road, to the North-West of the Borough. BPA’s imaginative design for this six-storey building features balconies and a roof terrace that look out across Ravenscroft Park with the steel-framed volume of Orwell House contained by Vandersanden’s multi-coloured greyish brick envelope. On the two shorter sides, this brick envelope is fronted by balconies clad in pink, glass-reinforced concrete (GRC) panels. This bold chequerboard patterning echoes the tones and patterns used by Lubetkin to animate facades on buildings across the existing estate.Completed in July 2020, Orwell House is a Finalist in the Housing Awards 2021. To find out more about the bricks used in this project or to see the wide range of high-quality bricks available from Vandersanden, click on the 'View more' link

The largest roof measures some 2500m2 and the inverted roof build up selected and supplied by SIG comprises IKO’s PermaTEC hot melt waterproofing system.

Located in Anglesey and operated by Bangor University, Menai Science Park is the flagship building for Wales' first dedicated science park. The facility is built to BREEAM Excellent standards and comprises of 5,000 sqm of offices, laboratories and workshop space for up to 700 people - from start-up businesses to large corporate companies. The building's structure features a striking white continuous flowing ribbon that forms wall, floor and roof surfaces and wraps around the glazed facade to the front elevation. The two-storey entrance connects to the main three-storey, traditional brick cavity U-shape building,m which houses the laboratories and offices and features a facade that encloses an open courtyard. Aluminium curtain walling from Technal was installed and spans 74m x 11m. This had to follow the curvature and flow of the ribbon at the point of fabrication. The key area for this facade is the first floor horizontal and sloping ribbon - the curtain walling continues behind the Corian rainscreen. One particularly challenging detail is the 6m glazed linking walkway that connects the innovation area to the brick-built main building. Designed with a double-pitched roof, the curtain walling follows the long contours across the two pitches of the roof at an angle. This involved calculations and modelling to accommodate the difficult compound angles to ensure the desired architectural intent was achieved. Throughout the building, aluminium casement windows have been installed, some as inserts within the facade including automatic opening vents, and to the courtyard elevations. Completing this contemporary outdoor space, the windows are complemented with timber rainscreen panels.

This project, to coat approximately 2000 sq metres of asbestos roof with the BBA Approved Asbestsoeal system is a lesson for all in correct health and safety. Liquasil provides all approved installers with H&S training as standard. This deals with correct use of netting, scaffold, walkways, work platforms and waste water filtration from asbestos roof cleaning. Having already completed 500sq metres on a unit a year previously, the contractor was invited back to complete the rest of the block, which is the best possible endorsement.

Glazing Vision have worked on a number of projects with Architects, ARCHEA, who are Victorian house experts specialising in adapting period houses into modern homes. These homes regularly demand an uplift in natural daylight, and Glazing Vision have formed a great relationship with ARCHEA to help transform many of their projects into well-lit, healthy, and happy environments for a number of families.These particular homes are all located within 10 minutes of each other in Hackney, London, with all clients looking to transform their period property into a contemporary home. Each project involved an extension and required a significant increase in natural daylight to help better the health and wellbeing of the families residing in each home which is where Glazing Vision stepped in.“When adding a ground floor extension, we often need to include rooflights to add light and views both to the new spaces and existing rooms in the home. Whilst fully glazed roofs can be used, this approach typically incurs more cost and extended lead-times due to the glazing being bespoke and needing to be made to order. By using large format, off-the-shelf rooflights we can incorporate extensive areas of glazing, but at a much lower cost and faster turnaround. We then use these in combination with traditional roof construction techniques, which are simple to construct and maintain.” – Richard Skinner, ARCHEA.ARCHEA regularly specify Glazing Vision’s Flushglaze Fixed Rooflight, a minimalist product with ‘frameless’ internal views designed to allow as much natural daylight into a room as possible. When working with pitched roofs, ARCHEA often opt for the Glazing Vision Pitchglaze Fixed Roof Window which is designed to be installed in pitched tiled roof applications flush with the tiling line, providing you with a vast amount of natural daylight.“We initially chose Glazing Vision because of their wide range of high-quality rooflights, and since working with them on a number of projects we value the help of their Technical Sales Team who are always on hand for technical support. We typically use the Flushglaze Fixed units as the extensions we work with usually involve a flat roof for practical and planning reasons and the Flushglaze offers the largest and best value standard glazing solution on the market. The standard aspect is vital for us as we are often looking for short lead times, and so this element adds so much value. When working with pitched roofs we instead use the Pitchglaze Fixed Roof Window which fit flush within the roof offering a sleek finish.” – Richard Skinner, ARCHEA.You can purchase our off the shelf rooflights and roof windows via rooflights.com, our online rooflight shop!Photography: Mai-ling Leung of ARCHEA

11 Freebournes RoadBauder reinforced bituminous waterproofing system with BauderSOLAR FSynopsisA large derelict warehouse located in Witham has undergone major renovation to transform it into a storage centre for Essex County Council that will assist its services and benefit the local community. The refurbishment works were designed and project managed by Lambert Smith Hampton on behalf of the client, who wanted the building to act as a benchmark for sustainability with the roof playing an integral part in achieving this through the addition of solar panels.Bauder Building BoardProject Name:11 Freebournes RoadLocation:Witham, EssexRoof Size:5,200m²Client:Essex County CouncilProject Manager:Lambert Smith HamptonApproved Contractor:Acclaim ContractsPV Installer:CJ SolarEnvironmental focus:Solar PVThe specificationWorking closely with the client, Bauder performed a comprehensive roof evaluation survey to identify the full extent of water ingress being experienced and to confirm the suitability of adding solar. The bespoke survey report highlighted that the roof needed to be stripped back to its original deck, before being waterproofed with over 5,200m2 of Bauder’s reinforced bitumen system by Acclaim Contracts. 588 solar PV modules were then fitted onto the roof by electrical installer CJ Solar, enabling the client to generate at least 134.70 Megawatt Hours of solar power each year. Products appliedBauderSOLAR FIntegrated photovoltaic system, where the modules and the substructure are combined to form a single unit, which is secured to the roof without any penetration of the waterproofing or roof deck. System installedReinforced Bitumen Membrane System1 Reinforced bitumen membraneTorch applied, elastomeric bitumen capping sheet2 BauderPIR M 60Rigid urethane foam insulation faced on both sides with aluminium foil.3 BauderPIR FA-TETorch applied air and vapour control layerAdvocacyJulian Sanchez, Commissioning Delivery Manager for Essex County Council: “We actively look for opportunities to implement renewable energy and knew that this storage facility lent itself well to PV retrofit.

A sense of community, abundant greenery and lake views on the roof terrace for all residentsThe housing fair is held annually in Finland. In 2021, it will be held in a scenic location in Lohja, Southern Finland. An interesting partnership quarter will also be put up in the fair area, where a sense of community has especially been taken into account in the planning. A block of 34 modern and energy-efficient apartments. The principal designer of the site is the architect Sasu Alasentie from UKI Arkkitehdit.”The idea behind the whole quarter is a sense of community. The flats in the building do not have their own saunas, but instead a communal use sauna will be constructed on the roof terrace. You can see the wonderful lake scenery from the roof and by utilising the roof terrace we wanted to ensure views of the lake to all residents. The yard areas of the quarter are fairly compact, but the roof terrace creates more greenery and communal outside areas for all the residents to use. We also hope that this will increase the residents’ team spirit and sense of community,” says Sasu Alasentie about the basis of the planning. ”On the roof terrace, we will also build an individual planting box for each resident, where they can cultivate herbs, flowers or whatever plants they want. A small summer kitchen corner and dining area will also be built there, as well as hanging chairs for lounging around. All in all, the area will hopefully become a communal, green oasis to spend time in, for all the residents,” says Sasu Alasentie. ”When we were choosing materials for the terrace, it was important to us that they would be in keeping with the building’s ecological nature and energy efficiency. Together with the contractor, we decided on the UPM ProFi Piazza composite for the terrace material. What appealed to us about it was particularly its durability and that it was easy to look after. Naturally also the fact that it’s made of recycled material, which fits well with the environmentally-friendly ideology of the whole building. I believe that in future projects, environmental friendliness and materials made from recycled materials will become even more popular,” says Sasu Alasentie.  

Rathbone Market is one of six schemes in the UK that has been delivered by English Cities fund (ECf), a regeneration partnership between Homes and Communities Agency (HCA), Muse Developments and Legal and General. Part of the 680,000 sq ft Canning Town & Custom House regeneration area programme, Rathbone Market was designed by Project Orange and formed the third and final phase of the entire development. Continuing its long-standing relationship with John Sisk and Son, one of the main contractors to the programme, RCM supplied a whole host of products for the successful development of the project.

A detailed visual and physical inspection, together with core and moisture probe analysis carried out by IKO on the roof, patio and walkway areas, indicated that the waterproofing membrane was in a condition commensurate with the age and the type of the traditional membranes installed. They had become fragile and brittle. The decks were saturated due to water ingress, and natural ageing had played a principle part in the deterioration of the waterproofing system. The build-up would not have met the requirements of the current building regulations Part L. IKO worked to refine the specification for the main roof,

Hundreds of homes have been refurbished as part of a multi-million pound revamp of housing association properties.Tristar Homes spent £8m on the scheme at Kennedy Gardens in Billingham where they carried out work on 225 properties across the three housing blocks as well as creating 12 new one and two bedroom homes which have been made available for rent.The development, completed in September 2014, includes the fitting of new windows, new bathrooms and improved living space due to the new balcony extensions.The roof area before its refurbishment had a U-value of 0.4 W/m²K. This existing build-up would not have met the requirements of the current building regulations Part L.The lower roof had been overlaid at least twice since its original construction. In all but one core sample, the existing insulation was wet through and therefore it was apparent that 90% of the existing roof build up needed stripping to the original asphalt. A further inspection was needed when the asphalt was exposed to ascertain the condition and depth of the asphalt. The asphalt was deemed in reasonable condition so the new system could be installed onto the original asphalt.IKO worked with installing contractors BriggsAmasco to refine the roof specification and recommended IKO Mach One single layer bituminous membrane system, installed to the recommendations of wind uplift calculations and performing to a 0.18U value as per requirements.IKO Mach One membranes are a robust, flame-free, single-layer roofing system with added fire-retardancy. IKO Mach One can be mechanically fastened, ballasted or bonded with polyurethane adhesive.A 20-year insurance-backedfire retardancy guarantee was issued to cover all materials, design and workmanship covering contractor insolvency.

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.

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".

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.

Abu Dhabi Airport Company signed a contract for the construction of infrastructure integral to the Abu Dhabi International Airport expansion. The project was set to be delivered across multiple work fronts including airside and landside airport operational areas. Surespan was asked to supply a number of 2-hour fire-rated, FACTA Class AA, SAC floor hatches with a free-standing guard rail to three sides and a hinged gate.

Teesside University’s Greig Building, named in honour of the founding father of computer science Bill Greig, is the home of the university’s Computer and Mathematical Sciences Studies department. When the aged bituminous roof coverings had shown failures including splits, blow holes and crazing, it was of paramount importance that a waterproofing solution could be provided as quickly as possible to prevent the risk of water damage and disruption.The university’s site maintenance team turned to Polyroof for a solution, which started with a detailed survey of the three roof areas totalling 750m2.The ChallengeCore tests taken at appropriate locations throughout the roof areas demonstrated that the existing warm roof build-ups were free from signs of decay. This meant that the roofs could be retained and over-coated with a new waterproofing system allowing for a rapid, minimal-disruption solution.A bespoke specification was put together based on the findings from the Polyroof Survey Report that provided a comprehensive set of recommendations, including remedial instruction for many problematic roof details. With the peace of mind and satisfaction that the various problems on the roof would be solved through Polyroof’s proposals, the client progressed with a tender process that resulted in a successful application by Polyroof Approved Contractor BBR Roofing Ltd.The SolutionPolyroof’s Protec System, a hybrid polymer liquid system with extremely fast curing and installation times was chosen as the ideal solution for the project. Due to its fully cold-applied application, the works could be carried out during the university’s term times, without having to wait for closure periods between semesters.Works began with the existing asphalt and felt coverings being made good where required, including the levelling and filling of blow holes and cracks with Polyroof Structural Repair Mortar. Next, the surfaces were thoroughly cleaned and degreased to provide a sound substrate for the new waterproofing system.Many of the roof perimeters and junctions featured parapet walls which were identified as a potential point of water ingress during the survey. The inner faces and tops were therefore boarded-over with 18mm Polyroof approved plywood which would allow these details to be fully encapsulated with the Protec System, meaning their waterproof integrity would be covered under the new system’s guarantee. Protec can waterproof vertical areas with the greatest of ease due to its thixotropic formulation, which means slumping and running is minimised during application.Polyroof’s extra-tough GRP trims were then installed to create neat and robust edge detailing for exposed perimeters before the main Protec system application commenced. After priming surfaces where required, the first coat of Protec was applied and reinforced with PolyMat 450. With its RapidCure technology, the Protec can be walked on and over-coated after only 30-60 minute after applications, meaning large roof areas can be made fully waterproofed within a matter of hours.After the second coat of Protec was applied to complete the waterproofing system, designated maintenance walkways were formed through embedding quartz sand aggregate into a third coat of Protec liquid.Completion and InspectionThe 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 BBR Roofing, 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 project consisted of two similar flat roof areas totalling 1,100m2 above high-rise residential blocks in a city centre location. The existing roofs were an inverted roof design that had been waterproofed with single-ply that had failed prematurely. Numerous short-term, localised repairs had failed to stop the water ingress and leaks had been a long-term problem.It would have been impractical to remove the tons and tons of ballast and insulation from the top of the high-rise building and it was imperative to the client that removal or replacement works were not involved at all. The specific nature of this project required careful consideration, and so a survey of the roof was arranged.The SolutionA report from an independent consultant commissioned by the client identified a problematic challenge with an overlay option. The existing falls of the roof were assessed to be poor, and so standing water would be an issue for any new waterproof covering. The report concluded that this would reduce the lifespan of an overlay waterproofing system and so was advised against. The client initially thought this to be a stumbling block and that costly and impractical modifications to the roof would need to be made.Having worked with Polyroof on scores of other projects, the client turned to Polyroof Technical Services for a solution that could meet their stringent criteria. Following on from the preliminary discussions, Polyroof’s Technical Services assessed the site, taking core samples and then providing a suitable specification to overlay the roof with the Protec System.The BBA certification of the Protec system specifically covers use for zero falls (completely flat) applications, meaning the client had absolute peace of mind that standing water would not be a detriment to the integrity of the waterproofing system. The client was able to achieve the original objective of an overlay system and benefited from the associated cost and time savings. Furthermore, the BBA certificate states that when used in inverted roof scenarios the lifespan of the Protec system is as long as the design life of the roof.Work was started with J R Flat Roofing, a Polyroof approved contractor with national coverage, moving the ballast and insulation to one-side in four phases of 140m2 at a time, exposing the single-ply membrane to which the Protec system was directly applied.Due to Protec’s rapid cure and walk-on times (30-60 mins dependent on conditions), the system is ideal for larger, phased refurbishment, as specific sections of the roof can be made waterproof with the full Protec system in one day. When carrying out the next section, the new Protec membrane forms a totally seamless and watertight joint to the existing Protec-covered areas.Another objective was to reuse the original inverted insulation and ballast pebbles as this was cost saving and negated the need for the lifting logistics that would have been involved in bringing the ballast to ground level. Additionally, it made the process as environmentally compliant as possible by keeping waste to a minimum. The insulation and pebbles were re-applied in its original format and, due to the weight of the pebbles, was a mammoth task that required three miniveyors to help with the handling. A series of special aluminium breather vents were also fitted down to the concrete slab roof substrate to enable the surface to dry out over a period of 12 months.The whole job was completed in three weeks and the client was delighted with the finished work. With a 20-year insurance back-guarantee and a maintenance-free waterproof membrane that will last as long as the roof stands, the client was once again left with total peace of mind that their buildings could not be better protected.

IntroductionFerrari World in Abu Dhabi is the world's first Ferrari theme park. The park includes 37 different rides and attractions and features the world's fastest rollercoaster “Formula Rossa” – reaching 240 km/h in 4.9 seconds. The park has been open since 2010 and has been nominated for numerous awards. Project:Ferrari World in Abu Dhabi needed a unique solution to allow for the maintenance of rollercoaster carts. Due to restricted space, a sliding hatch was proposed to allow easy craning in and out.Products Supplied Surespan manufactured and supplied an SLHE Aluminium, thermally broken, single leaf, electrically operated, sliding roof access hatch. The hatch was a large 5400 x 4000 structural opening sliding hatch.A sliding hatch allowed maximum clear space. Operated by a 230v geared motor.

Architects Dixon Jones specified 600m2 Junckers solid oak flooring for Marlborough Primary School, a multi award-winning building on a densely populated urban site in the Royal Borough of Kensington & Chelsea. The brief to create a primary school much larger than the original Victorian building on the existing site challenged Dixon Jones to design a school where teaching accommodation is arranged vertically around a series of cascading roof terraces. With nursery and reception classes on the ground, children progress upwards through the building the older they get, with the junior years arranged on the upper floors. The interior forms an equally dynamic environment for students and staff with teaching spaces arranged around communal halls and generous circulation areas. A large main hall and multi-use space, flooded with natural light from two central roof lights, features Junckers wide board oak flooring throughout, providing a natural, unifying backdrop. Junckers’ FSC and PEFC certified floors are a durable, long-lasting choice with low lifecycle costs. Made in solid wood, the floor can be sanded and refinished multiple times without losing its good looks or performance, ideal for a thriving community school.
