The Vent3 Pro 165gsm Breathable Membrane is a high-performance solution crafted with heavy-duty, triple-layer fabric, ideal for universal breather applications on both roofs and walls.

Constructed from high tensile spun bonded polypropylene layers enclosing a micro-porous film, this membrane boasts superior moisture vapour permeability while maintaining waterproof properties. Its printed green upper surface, with preprinted marking lines, and white underside, enhance its ease of use and installation. Engineered to withstand various weather challenges, it effectively allows water vapour to escape from roof structures while shielding against wind-driven rain, snow, and dust. With its excellent tensile and tear strength, it is BBA certified, BS 5534:2014+A2:2018 compliant.
