Product Description

Cromar Vent 3 Pro is a triple layer fabric, high performance breather membrane. Made from high tensile, spun-bounded polypropylene layers around a micro-porous polypropylene film, Vent 3 roofing felt ensure ultra-high performance.

The waterproof benefits and vapour permeability is combined with excellent tensile tear strength. It allows water vapour to escape from within a roof structure while also protecting against the various elements. This includes wind-driven rain, snow and dust, which could risk penetrating the primary roof waterproofing. So you can rely on a permanent quality breather underlay to last the life of the roof construction.
