Fatrafol 804 – Finishing

The membrane is intended only as a supplement of FATRAFOL reinforced roof membranes. It is used for detailing and for broken parts of roofs insulated by FATRAFOL membranes. The membrane is not suitable for covering the whole area, mechanically anchored ply covering. Fatrafol 804 is an unreinforced roofing membrane (homogeneous) based on PVC-P. This product is resistant to both weather conditions and UV radiation.

  • membrane with a thickness of 1.2 mm is covered with 12 years of warranty and 1.5 mm thick 15 years;
  • during installation, the lower covering material must be at least 0.5 mm thick.
  • the coatings can be interconnected by hot air welding, but the ambient temperature must be above -5 ° C.
