Certificate type
Flexible Polyolefine (FPO) single-ply waterproof membrane with fire retardant.
Flexible Polyolefine (FPO) single-ply system with non-halogenated fire retardant, designed for mechanical fastening on warm roofs.
System (can) include:
- Waterproof membrane:
Sarnafil TS77 membranes are manufactured using a specially developed in line extrusion coating process. This coats both sides of a polyester scrim carrier simultaneously with a compounded Flexible Polyethylene and produces a dynamically stable membrane that can accommodate the tensile stresses imposed by mechanically fastened applications.
The process enables between 2% and 5% of recycled material to be used in the production of new membranes.
- Fleece (cushion layer):
A polypropylene fleece used either as a protective layer below the waterproof liner or as a protective layer on top of the liner.
Performance:
Certified by BBA to have a life expectancy in excess of 25 years.
Installation:
- Waterproof membrane:
Sarnafil TS77 is intended to be mechanically fastened using the Sarnafast or Sarnabar systems. Installation is carried out by Sarnafil contractors, who are specifically trained in the installation requirements of Sarnafil T membranes.
- Fleece (cushion layer):
Sarnafil Type A and Type T:
Sarnafil Type A and Type T are generally loose laid, but can be partially bonded to the substrate with Sarnacol 2170 or Sarnacol 2172 if required. In either application, all edges must be overlapped by at least 100 mm.
