Flexible Polyolefine (FPO) single-ply membrane with non-halogenated fire retardant, designed for mechanical fastening on warm roofs.

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.


Certified by BBA to have a life expectancy in excess of 25 years.


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.
