3 layer waterproofing breathable roofing membrane Material: A three layer highly breathable, fully waterproof membrane, constructed from high tensile spunbonded polypropylene layers, around a microporous polypropylene film. The outer layer forms the functional waterproof surface the middle layer is the breathable waterproof membrane and the inner layer protects the membrane from abrasion and damage, also giving additional strength. This enables the fabric to allow moisture vapour to pass through, whilst remaining fully waterproof. We can provide various colors on upper surface, printed with the trade name and head lap lines.
Use: Breathable roofing underlay positioned immediately above the insulation layer in a warm pitched roof, or in a cold pitched roof (ventilated or unventilated). Breathable roofing underlay for use under tiles and sheeted roofs, over open rafters or on to fully boarded substrates. Breather membrane for timber frame wall construction.
