Flexible Polyolefine (FPO) single-ply membrane for ballasted warm roofs and inverted roofs.

Sarnafil TG66 membranes are manufactured using a specially developed in line extrusion coating process. This coats both sides of the glass-fibre carrier simultaneously with a compounded Flexible Polyethylene to produce a dynamically stable membrane, which is suitable for adhered and loose laid ballasted 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 TG66 is intended to be loose-laid and ballasted. Installation is carried out by Sarnafil contractors, who are specifically trained in the installation requirements of Sarnafil T membranes.
