Sell Waterproofing Permerable Membrane

The water-proof roofing breathable membrane is a three layer highly breathable, fully waterproof membrane, constructed from high tensile spun-bonded 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 it to the outside, whilst remaining fully waterproof. The membrane is waterproof and breathable. It is widely used in construction for roofing felt and underlay. We’ve established business relation with clients from UK, US, UA, Italy, Greece, New Zealand, Germany, and so on.
