Product details

Product description

Vent3 is a heavy-weight, triple-layer fabric, high-performance breather membrane, made from high tensile spun bonded polypropylene layers, around a micro-porous polypropylene film. Designed for use as a universal breather membrane for roofs and walls boasting superior moisture vapour permeability. Vent3 has a printed blue upper surface with preprinted marking lines and a white under-face. The high vapour permeability and waterproof properties of the membrane, combined with excellent tensile/tear strength, make Vent3 an ideal product for use in all pitched roof applications. It will allow the escape of water vapour from within the roof structure whilst protecting against wind driven rain, snow and dust which may penetrate the main roof waterproofing, providing a permanent quality breather underlay, which will last the life of the roof construction.
