Cromar Vent 3 Pro Breathable Membrane 1m x 50m comprises a micro-porous polypropylene film surrounded by a 3-layer fabric breather membrane. With its printed light green upper surface and white underside, Vent 3 Pro suits all roofing systems, including tiled, slated, and metal roofs.
The membrane’s high-vapour permeability, waterproof nature, and excellent tensile/tear strength make Vent 3 Pro an ideal product for use in warm and cold roof applications.
Cromar Vent 3 Pro Breathable Membrane 1m x 50m is appropriate whether draped unsupported over rafters or laid directly over insulation. Providing a permanent quality breather underlay, which will last the life of the roof construction, will allow the escape of water vapour from within the roof structure and protect against wind-driven rain, snow, and dust.
