General information about BEVENT W Monofilament Spacer Layer

Metal roof systems

Open structure prevents the accumulation of water

BEVENT W is a three-dimensional fabric made of randomly arranged PP monofilaments. It is used as a ventilation and spacer layer between the roof structure and the metal cladding.

The open structure of the fabric prevents the long-term accumulation of water. It forms an air-conveying layer with a void ratio of more than 95%, which effectively prevents the build-up of condensation.

At the same time, BEVENT W efficiently decouples the metallic cladding from the subsurface and thus minimises sound bridges. This significantly lowers the noise level. BEVENT W is used in all applications where a roof underlay has already been laid.
