High Breathable Roofing Unerlayment

Material: 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, whilst remaining fully waterproof. We can provide various colors on upper surface, printed with the trade name and head lap lines.
