"single ply roofing"

The £14m Arnold Hill Academy is part of the Priority School Building Programme (PSBP) and is being constructed adjacent to the existing school in Nottingham. The new Academy’s 3,570m2 flat roof covers 8,200m2 of replacement teaching space, science labs, an indoor sports hall and a drama studio. The project team at Wates Group had already identified potential roofing products. Due to the unconventional roof specification they asked SIG Design & Technology to recommend a product that would work in tandem to deliver the required performances.

The waterproofing to a large residential flatted development in London was carried out using the Koster TPO membrane.This warm roof design incorporated the Koster TPO Fleecebacked membrane mechanically fixed through PIR insulation, Koster Vapour Barrier and into the timber substructure as per the wind load calculation.An interesting project with many challenges that were all individually designed by the Koster technical team in collaboration with the project architects.The final roof incorporates hard standing areas, sedum and green roof sections, a solar panel farm and decorative stones.A beautifully deigned and usable area providing residents an amazing view over London.

The Koster TPO Single Ply Membrane was chosen to overlay an existing and failed flat roof on a coastal school on the Isle of Man. The Koster TPO was carefully designed and installed over the old asphalt covering to thus extend the buildings life and provide a safe environment for the pupils and teachers. The Koster TPO was fully bonded and mechanically fixed to the main roof substrate in order to combat the anticipated wind loading. for more information please contact admin@kosteruk.com

A new extension and internal fit out was designed by Wright and Wright Architects of London. It gave a modern and fresh look to the original 18th century listed building. New Gallery space, a cafe, and leaning spaces have all been incorporated into the new building.Koster Aquatecnic Ltd were involved in this project at an early stage. We gave advice on the below ground areas as well as the waterproofing for the green roof.The Koster TPO Single Ply Membrane was selected as the material of choice to cover the flat roof section primarily due to its the environmental characteristics. The Koster TPO membrane is recyclable, contains no PVC, and is the most robust and longest lasting membrane on the market. The Slate Grey color (RAL 7015) was selected as it would blend in with the overall look the clients were trying to achieve. This project was fully Electronically tested prior to the green roof sedum blanket being installed.

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.

Replacing the roof on Primark’s 640,000 sq ft distribution centre in Thrapston, was the largest refurbishment of a single-ply roof undertaken in Britain in 2012 and clearly demonstrated Bauder’s status as one of the largest and most respected companies in the roofing industry.

IKO Polymeric, SIG Design & Technology, and Excel Roofing Services have collaborated to design, supply and install 250m2 of single ply roofing for the new kiosk, glass covered beach walkways and stores which houses the latest Oceanarium residents, ten Humboldt Penguins.

A green roof system was selected for this project as the client required a roof that would complement and accommodate the step in levels to follow timber decking lines to the 55m² roof terrace areas. IKO Single Ply’s Spectraplan SM120 light grey single ply waterproofing system was overlaid to the existing roof and newly built sun rooms, ready to receive a green roof system.

The roof area was badly damaged by heavy storms, with all existing ballasted solar panels lifting off the single ply roof and destroyed beyond repair. The client needed the remedial work completed to fixed deadlines in order to comply with insurance requirements, and wanted to optimise the roof by replacing the pre-existing photovoltaic (PV) array with a solar solution that would deliver superior energy generation. The office also had to remain operational throughout the works, creating logistical challenges

The new Leeds Arena was a £60m project by Leeds Council to create a striking new stadium, which has been crowned with a 7,500sq m Sika Sarnafil single ply roofing system, installed by experienced contractor Lakesmere. The fact that Sika Sarnafil was the first roofing manufacturer to be BIM ready played a huge part in the specification, and in turn improved the ability to review designs and rationalise ideas, whilst cost saving using BIM was highlighted through material specifications and design coordination.

The roof to a Waitrose distribution centre has been completely refurbished in a single ply membrane system chosen for its sustainable credentials and no disruption to the retailer’s 24/7 operations at Aylesford near Maidstone, Kent. Supplied by SIG Design and Technology, 10,200m2 of IKO’s Spectraplan single ply membrane was specified for its ability to contribute to a BREEAM Very Good rating for the project which is in line with Waitrose’s mission to ‘tread lightly on the environment’.

Following the success of the Shoreline and Ocean hotels at Butlins’ Bognor Regis Resorts, the Butlins Wave Hotel is the newest addition, with the widest range of accommodation options. All three have been waterproofed by the Roofline Group. Cefil single-ply roofing membrane covers tapered insulation, with Fixfast tube washers and fasteners holding it all in place against the prevailing sea winds."We always get good service from you guys - that's the main reason we've stayed with you all these years"Bryan Lock - Project Manager at Roofline Group Ltd

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.

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.

Over 1,200m² of Protan SE 1.2mm PVC single-ply membrane was installed in the Protan Vacuum roof system at Butlins Splashworld, Skegness. The roof system required no mechanical restraint or adhesives (except for around the roof perimeter and penetrations), as it relies upon the wind to keep the membrane in place with the help of Protan vacuum vents installed at locations designed by Protan's Technical Services Department. William Bird of Protan partner roofing contractor, Roofdec Ltd, commented, "Protan's vacuum roof system is quicker to install than conventional fully-adhered or mechanically-fixed systems."

Sandbanks Court apartments are situated within the expensive up-market area of the Dorset coastal peninsular and enjoy spectacular panoramic views across the sea. A green roof system was selected for this project as the client required a roof that would complement and accommodate the step in levels to follow timber decking lines to the 55m² roof terrace areas. IKO Single Ply’s Spectraplan SM120 light grey single ply waterproofing system was overlaid to the existing roof and newly built sun rooms, ready to receive a green roof system.

The Koster TPO Single Ply membrane was selected to waterproof the flat roof on this new build development. The design called for a warm roof system installed over a timber deck followed by a sedum blanket (on protection membrane).Koster TPO 2mm Fleeceback membrane was used as it is highly resistant against mechanical damage, fully weldable so no weaknesses and it will not contaminate any of the planting such as a PVC membrane would.The Slate Grey RAL 7015 colour was selected to compliment the Zinc cladding.

Barony CampusBauder Thermofol PVC single ply waterproofing system withBauderSOLAR FSynopsisBarony Campus is a new build project situated in Cumnock, Scotland. The campus will incorporate a range of primary schools, learning centres and academies within the area, and is the biggest capital project undertaken by East Ayrshire Council.Bauder Building BoardProject:Barony CampusLocation:Cumnock, ScotlandProject type:New buildRoof size:5,230m²Client:Sheppard RobsonMain contractor:Morrison ConstructionApproved contractors:EJ ParkerW.G. Walker & Co                             Q9 Cladding SolutionsThe specificationThe client required flat roof waterproofing as well as a sustainable energy source in the form of solar PV panels. Due to Part L regulations there was a requirement for a large PV array. Main contractors, Morrison Construction, bought into the risk-averse, zero-ballast, zero-penetration solution that the BauderSOLAR system offers. As Morrison Construction had not yet used this system, Bauder conducted a technical seminar to share the benefits of using BauderSOLAR in conjunction with a Bauder single ply membrane and to discuss the acoustic considerations for a building of this nature.The technical support and advantages of a single-source supplier resulted in a specification of a 176.80kWp BauderSOLAR PV system generating an estimated 157,800kWh per annum. The system proposed by Bauder ensured the solution was compliant in relation to the SAP calculations that had been carried out.Products appliedBauder THERMOFOL PVCThis single ply membrane is lightweight and has a high-grade virgin polymer formulation. The PVC formulation ensures it is resistant to chemicals and micro-organism attack making it well suited to receive a green roof.BauderPIR M 60This PIR insulation has aluminium foil facing on both sides and rebated edges to remove a thermal bridge. The matt black facing on both sides enables the board to be installed either way up. BauderSOLAR FThe lightweight, integrated system ensures that the integrity of the roof is upheld throughout the installation of the PV array. The panels are designed to create a 12º angle with modules delivering up to 455w per panel.Project challengesThe client had limited space for the storage of 544 solar panels and they could not be stored on the single ply roof. To overcome this, deliveries of the panels were coordinated with the roofing contractors finishing sections so that the panels could be raised, installed and welded as they arrived to site, mitigating the need for storage. Due to the reduced labour time of BauderSOLAR compared to ballasted systems, the site team managed to install the system quickly and efficiently, making back time lost due to weather delays and enabling the deadline to be met.The BauderSOLAR system is the lightest system on the market at 11.5kg/sqm. The system is also warrantied in combination with the roof membrane to ensure peace of mind is given to the client if any leaks or damage were to occur.System installedBauder Thermofol PVC single ply system1 Bauder THERMOFOL U15 FR1.5mm polyvinyl chloride membrane (PVC) reinforced with a pre-coated polyester cross-weaved matting for mechanically fixed installations. 2 BauderPIR M 60This efficient tissue-faced flatboard insulation has been specially developed for use within Bauder single ply systems. 3 BauderSYN DB-PE 100A blue, polyethylene air and vapour control layer.

However, we found some challenges getting started due to the bad weather but once we finally began it was very straight-forward and fast to install. The technical help received from Chris and the team from design through to project completion was second to none.” 

Blue-green roof solution on a London dwellingCHALLENGE8a Belmont Street comprises two unique semi-detached dwellings, which have been constructed in Chalk Farm, London by a private developer Maygrove Projects in collaboration with Martin Evans Architects. The total roof area covers only 55.03m² but features an unusual roof design; it is divided into five sections comprising two glazed roofs and three blue roof areas. For this warm roof construction, an alternative durable waterproofing was sought, suitable for blue roof application. SOLUTION Approved Roofing Contractor Gribben Solar Roofing provided an alternative blue roof solution to the original design proposed by the project architects, fully complying with their needs. Together with partner and single ply manufacturer RENOLIT they proposed a waterproofing solution for the blue roof in the form of a fully bonded RENOLIT ALKORPLAN L35A77 membrane, to be combined with the RENOLIT ALKORPLAN Green roof system. So, actually, a blue-green roof!

Nobu Hotel is a new development in Shoreditch, East London, and was opened by Hollywood legend Robert De Niro and Japanese chef Nobu Matsuhisa in May 2018.The design of the five-storey building – which has 150 hotel rooms and suites – is a nod to the area’s industrial past with a ‘frayed edge’ look of stepped balconies formed with glass fibre, reinforced concrete and cantilevered steel beams. The design has also been likened to that of a cruise ship and received much critical acclaim.The roofing system covered 1500 sq. m, which included a green roof area and tiered balconies.

To create a Blob... CHALLENGE For the design of a Texaco service station on the highway near Antwerp the architect decided he wanted to create a Blob (Binary large objects) architectural design. The service station consists of three functional lobes that together look like an oil stain. The actual gas stations are covered with 4 lobe-shaped canopies. To accentuate this futuristic design the architect wanted to create liquid formed shapes in a metallic look. As the walls of the main building were planned using a polurea metallic finishing coating the architect sought a suitable compatible material to finish the rest of his Blob roof surfaces. SOLUTION Synthetic roofing membranes are the most flexible materials on the market and are suited to waterproof almost all possible roof shapes. For this particular project the silver coloured RENOLIT ALKORPLAN membrane was the best solution. This silver membrane is produced with a protective coating creating a roofing membrane that is easy to clean. The RENOLIT ALKORPLAN Metallic membranes combine excellent durability with added aesthetical appearance.

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.

In a complex new build roofing project that was deemed almost impossible, Contour Roofing stepped up to the challenge with a Sika Sarnafil membrane. With truly stunning results, the project impressed the judges of the prestigious NFRC UK Roofing Awards, winning the Single Ply category. In partnership with Sika Sarnafil, Contour quickly presented a new bespoke specification; an adhered system using Sarnafil G410-15ELF Lead Grey with a polyester fleece backing as the main roof sheet for a flawless result and Sarnafil G410-15EL Lead Grey for all the detail work flashings.

Financed by county council capital funds, Northamptonshire County Council undertook a multi-million pound remedial works programme on a number of schools originally built in the 1960’s and 1970’s. All of the buildings were suffering from some degree of water ingress, and the roofs needed to be brought in line with current building regulations for improved thermal performance. Sika Sarnafil’s specialist roofing contractors installed over 50,000m2 in light and lead grey of G410-18EL single ply membrane to the school roofs.

Canberra HouseBauder Cold Applied LiquiTOP SystemSynopsisCanberra House is an office facility in Swindon. The existing single ply PVC waterproofing system roof was leaking and so Bauder carried out a full site survey. The resultant report gave the client several options to rectify the leaking roof.Bauder Building BoardProject nameCanberra HouseLocationSwindonProject typeRefurbishmentRoof size985m²SpecifierRapleys LLP (Bristol)Approved contractorCentral Roofing & Building Services LimitedThe specificationThe LiquiTOP system was chosen as it can be applied directly to the prepared and primed existing single ply covering. The liquid system allowed us to get into tight spaces and without the need for any hot works.LiquiTOP is excellent on refurbishment projects where the complexity of the roof involves intricate areas to be detailed that are not easily achieved with a sheet membrane, or the actual working space on the roof is constricted.Project challengesLarge areas of plant and machinery were situated just above the roof level making access to the areas below difficult with the plant in-situ. The available budget on this project did not allow for lifting or removing the plant, stripping the existing waterproofing system, and replacing with new. Therefore, the decision was made to overlay the existing single ply membrane with a cold applied liquid waterproofing which can be installed without the need to raise any plant.To overcome drainage challenges, secondary upstands were created under the plant and fabricated channels placed underneath allowing water to flow through to the drainage points.The resultBauder was able to offer a cost-effective solution without the necessity to remove or decommission the roof mounted plant and machinery. Cost reductions were achieved for the client by overlaying the existing roof, negating any need to strip existing materials, and not having to remove or raise the plant.The works were carried out by Central Roofing who manged the project impeccably and also finished ahead of schedule.System installedBauder Cold Applied LiquiTOP System1 LiquiTOP PU cold applied liquidA moisture triggered curing polyurethane waterproofing resin; applied in 2 coats, reinforced with Bauder LiquiTOP Glass Fibre Mat.

When a Vue Cinema on the outskirts of Doncaster needed a section of the asphalt flat roof refurbished as part of extension and maintenance works, a zero odour solution was required that would allow the building to stay open to the public throughout installation. A liquid waterproofing product was considered ideal to avoid the need for complex edge detailing associated with single ply or bitumen products around the plant.
