Jump to:
+44 (0)1707 394444

A Flexible Polyolefine (FPO) single-ply membrane with a 200 g/m² polyester fleece laminated to the underside, designed to be fully adhered to the substrate.

System includes:

  • Sarnafil TG76 waterproof membrane.
  • Sarnacol 2142s or 2172 spray adhesive.

- Waterproof membrane:

Sarnafil T/TC 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.

- Adhesive:

Sarnacol 2172:

Spray applied PU-based contact adhesive (red-coloured), designed to adhere Sarnafil G410-EL or G410-ELF waterproof membranes to substrates of steel, timber, concrete, or approved thermal insulation boards. Substrates should be solvent-resistant, dry and free of oil and grease.

Sarnacol 2142s:

Polyurethane-based adhesive, designed to adhere Sarnafil G410-ELF or TG76-Felt waterproof membranes to substrates of timber, concrete, or thermal insulation board.

Substrates should be solvent-resistant, dry and free of oil and grease.


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


Sarnafil TG76 Felt can be adhered to timber, concrete or suitable thermal insulation boards, with Sarnacol 2142S or 2172 spray adhesive. Installation is carried out by Sarnafil contractors, who are specifically trained in the installation requirements of Sarnafil T membranes, including the correct method of forming laps using Sarnafil T Prep, prior to hot-air welding.
