Waterproof/breathable and vapor permeable roofing membrane
The main function of the breathable roof membrane is to reduce the amount of heat lost by air leakage through the ceiling and from the loft space to the outside. Up to
? Made by two layers of non-woven fabrics and one layer of microporous polymeric membrane in the middle. The three layers are thermally laminated without using any chemicals such as glues.Outer layer forms functional waterproof surface
Middle layer breathable waterproof membrane
Inner layer protects from abrasion and damage, also giving additional strength
Enables fabric to allow moisture vapor to pass through and whilst remaining fully waterproof
Breathable roofing underlay for use under tiles and sheeted roofs, over open rafters or on to fully boarded substrates
Constructed from high tensile spun-bonded polypropylene layers
Higher levels of water-resistant
