Product description
Asphalt roofing felt W / PV – SBS is made on the basis of a polyester nonwoven fabric. The coating is SBS modified asphalt. The top side covered with coarse mineral sprinkles, the bottom side with fine grained sprinkles. Designed for use on wooden, steel or concrete substrates as a primer or top layer in multilayer roofing on roofs with a slope of 3 to 75o. For a period of 2 years, it can be a temporary, single-layer waterproofing protection against subsequent covering with sheet metal, tiles or asphalt shingles.
Destiny:
- making the top layer in multilayer roofing
Mounting method:
The roofing felt is mechanically or glued to the surface using asphalt. The roofing felt should be fastened at a temperature not lower than 0ºC, on a dry surface, with a longitudinal overlap of about 9cm and a transverse overlap of about 12cm. In the case of mechanical assembly, fasteners should be evenly spaced along the roofing felt. After fixing with connectors to the ground, the plant must be glued thoroughly to obtain a watertight waterproofing coating.
