Rhepanol is the world’s premier single ply membrane. This membrane is completely inert, there are no harmful plastizers or toxins in the membrane. This membrane has a longer life expectancy compared to many alternative roof coverings.

The joints in Rhepanol HFK membranes are sealed by hot air welding. This membrane can be installed in 3 x ways bonded, ballasted or mechanically fixed with our unique grip fix system. The roll width of the membrane is now available up to 1,50Meter wide, which makes it significantly wider, leading to quicker instillation time.

Rhepanol HFK has also recently passed all FLL testing for Root Resistance, making it suitable for green roofs, the new Rhepanol HFK is one membrane that covers all systems.

Rhepanol is also available with a coating which we can apply over the membrane, the coating is available in copper / green or silver.
