The Pinnacle Decoupling Membrane is a polypropylene membrane with rounded square shaped studs that form channels specially designed to embed and fasten the electric heating cables.


About this product

The Pinnacle Decoupling Membrane is a polypropylene membrane with rounded square shaped studs which form channels specially designed to embed and hold the heating cable. On the  underside of the membrane there is a nonwoven thermo-welded polypropylene fabric that ensures the membrane fixing is secure to the membrane.

The Pinnacle Decoupling Membrane is a decoupling membrane of 5.5mm thickness that does not require expansion joints in the screed before laying ceramic and natural stone tiles.

The decoupling membrane acts as a guard against movement in the sub floor which can cause tiles to crack.

For the floor heating system to operate at its most efficient, an insulation board is recommended to be installed below the decoupling membrane.

Substrates that are suitable: Concrete Floors, Timber Floors, Plywood Panels, Cement Screed, Anhydrite Screed & Green Screed
