Synthetic roofing sheet with glass-fibre reinforcement, FPO, bitumen compatible
The POLYFIN maintenance walkway membrane is an FPO membrane with a textured surface that is used for walkway protection of flat roof waterproofing (e.g. walkways for maintenance work). Due to thermally induced changes in the length of the product itself, and also of the roof sealings on which it is laid, a certain evenness in the surface cannot be guaranteed as a property. If this is necessary on the object, it is recommended to form the maintenance paths with concrete slabs (check statics), or to install a walkway grating system anchored in the supporting structure.
