Find out moreThis Vent 3 light breather roofing felt from Cromar is a triple-layer, high-performance breathable membrane that has been manufactured from two high tensile spun bonded polypropylene layers, thermally calendared to a microporous polypropylene film, with a plain grey lower surface and printed grey upper surface.
Designed for use in unsupported or completely supported metal, slated or tiled roof systems, this Vent 3 Light roofing felt has the highest levels of resistance to water whilst maintaining full moisture vapour permeability. Its waterproof nature, high vapour permeability, and outstanding tear/tensile strength make it the perfect choice for use in cold and warm roofs.
Ideal for laying directly over insulation or draping unsupported over rafters, this Vent 3 Light membrane will let water vapour escape from within your roof structure while protecting it against wind-driven dust, snow and rain which might penetrate the main roof waterproofing. Delivering a permanent quality breather underlay, this roofing felt will last the life of the construction.
