Cromar Vent 3 Light: 50m x 1m

Cromar Vent 3 Light Breather Membrane (50m x 1m)

This 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.
