Vent3 PremiAir is a triple layer fabric, high performance breather membrane, made from high tensile spun bonded polypropylene layers, around a polypropylene functional layer. Designed for use in a fully supported or unsupported tiled, slated or metal roof system. Superior air & moisture vapour permeability is achieved whilst maintaining the highest levels of water resistance. Vent3 PremiAir has a printed blue upper surface and white under-face.
The high air & vapour permeability and waterproof nature of the membrane, combined with excellent tensile/tear strength, make Vent3 PremiAir an ideal product for use in both warm and cold roof applications. Vent3 PremiAir is equally suitable whether draped unsupported over rafters or laid directly over insulation. 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.
