We are a Fatra approved contractor and fit Fatra's PVC membranes (Fatrafol, FF810 and FF807) regularly: BBA certified, root resistant, welded with hot air into one continuous sheet, and backed by a 20-year Fatra guarantee. From a 48 m² garage in Sheffield to a 4,500 m² ice rink.
Fatra a.s. is a Czech manufacturer of plastics and one of the bigger names in European single ply. Its PVC roofing membranes are sold as Fatrafol, and in the UK by product codes such as FF810 and FF807. Fatra UK, based in Cardiff, supports architects and installers here with specifications, fixing calculations and site visits.
A Fatra roof is a single layer of flexible PVC. The sheets overlap, and each lap is welded with a hot-air welder running at 450 to 550 °C, which melts the two layers into one. There are no glued joints to open up and no torches on the roof.
We are not Fatra. We are an independent single ply roofing contractor in Kilnhurst, South Yorkshire, and a Fatra approved contractor. Fatra is one of seven manufacturers whose systems we are trained on, and one we fit regularly. Our roof at New College, Oxford won an SPRA award for detailing in 2024. When Fatra suits the job, and especially when it is already in the specification, we are the people to call.
Fatra makes more than one roof. These are the single ply products you are most likely to see on a UK specification, and what each one is for. We fit the whole range.
Polyester-reinforced PVC, fixed through the laps into the deck and hot-air welded over the fixings. 1.5 mm as standard, 1.2 mm also made. Dark grey (RAL 7012) or anthracite (RAL 7016). The membrane on our Sheffield green roof.
A fleece-backed PVC membrane bonded to the substrate with Fatra's own adhesive, so there are no fixings through the roof. 1.5 mm or 2.0 mm, in dark grey, light grey or anthracite.
Unreinforced PVC that can be heated and formed around corners, pipes and outlets. Fatra makes it for details only, never as the main sheet.
A textured 1.2 mm PVC walkway, welded onto the roof to mark a safe route to plant, rooflights or outlets and protect the membrane underneath.
Pre-grown sedum in 540 × 540 mm recycled trays that clip together over the membrane, each holding around 20 litres of water per m². The system on our Sheffield green roof.
Fatra also makes felt, liquid and hot melt systems. This page is about its PVC single ply.
Taken from Fatra's datasheets and BBA certificates, not from a sales brochure.
FF810 and FF807 each hold a BBA certificate (02/3921 and 04/4079). The BBA puts their service life at over 30 years in normal conditions, with regular maintenance.
BROOF(t4) external fire performance in the build-ups Fatra has had tested.
Tested to EN 13948 and the FLL procedure, so the same membrane can sit under a sedum or wildflower green roof.
Fatra's PVC can be recycled, and Fatra quotes an A+ BRE Green Guide rating and ISO 14001 environmental management.
For a mechanically fixed roof, Fatra's technical department works out the fixing layout for the building's wind loads. We fix to it.
Fatra issues its 20-year guarantee after its own field technician has inspected the finished roof, so a second pair of eyes checks our work.
Chris visits, measures the roof and looks at the deck, upstands and outlets. You get a written quote that names the Fatra system.
Fatra's technical team can write the specification and calculate the fixings. On our Sheffield green roof, Fatra wrote the spec and we built to it.
Vapour control layer and insulation for a warm roof, then the membrane: FF810 mechanically fixed, or FF807 bonded down.
Seams are hot-air welded with laps of at least 50 mm. Test welds are tear-tested before work starts, and the finished seams are probed.
Fatra's field technician inspects the finished roof, then Fatra issues its 20-year guarantee. Ours is a 20-year workmanship guarantee on top.
Going under a green roof? We also test the finished membrane electronically before any sedum goes on, because once the trays are down nobody can see the waterproofing.
Three Fatra roofs we have fitted, two of them with full write-ups.
4,500 m² of Fatra PVC warm roof on a coastal ice rink shaped like a 50p piece, with steep gradients and North Sea wind. The rink stayed open for skating through the eight-week install. Skyguard worked as the specialist sub-contractor.

A 48 m² Fatra FF810 warm roof on a new stone garage, built to Fatra's specification, electronically tested, then finished with pre-grown Fatra Modular Tray sedum. Fatra's warranty was registered in June 2026.

A Fatra PVC single ply roof on a house extension, with welded upstands where it meets the house and the balcony outside the first-floor doors. It is the photo at the top of our home page.
The price gap between the single ply manufacturers we fit is small, so choosing Fatra rarely changes the budget much. The roof's size, access and insulation matter far more.
We are a Fatra approved contractor. Send us the specification and drawings. We price to it, build to it, and work with Fatra's technical team and field technician through to the final inspection. On our Sheffield green roof the architect drew it, Fatra wrote the specification, and the contractor has since come back to us for their next green roof.
