General information BEVENT SK Structured Separating Layer

Metal roof systems

Roof underlay membrane and ventilation layer in one

BEVENT SK is a bond of a a three-layer vapour-permeable separating roof underlay membrane and a randomly arranged monofilament wire mat. The product is equipped with a self-adhesive butyl stripe.

BEVENT SK serves as a ventilation and spacer layer between the roof structure and the metal cladding. The open structure of the randomly arranged monofilament prevents the permanent accumulation of water, and the vapour-permeable roof underlay membrane provides the highest level of protection against the elements during the construction phase.

The membrane also ensures that any residual moisture from the construction phase can escape and that moisture collecting on the surface of the membrane is drained away and discharged from the roofing system.

At the same time, BEVENT SK's randomly arranged monofilament efficiently decouples the metallic cladding from the substructure and minimises sound bridges. This results in a reduction in noise levels.
