Sarnafil is a single ply membrane that is strong and flexible, in either PVC or FPO material. All permanent joints are fusion welded via a hot air heat welding process, making it perfect for waterproofing flat roofs. Used since the 1960's, it has been a popular choice for Britain's education, commerce, retail, leisure and travel buildings, along with millions of domestic installations worldwide. It can be either mechanically fixed, fully adhered, or loose laid ballasted to the roof surface.
