polythylene polypropylene synthetic roof underlayment membrane is a three layer highly breathable, fully waterproof membrane, constructed from high tensile spun-bonded polypropylene layers, with a microporous polypropylene film inside. The middle layer is the breathable waterproof membrane, and the outer layers 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.
In addition to the above features, we also offer cheap breathable membrane and breathable roofing membranes. Our cheap breathable membrane provides excellent breathability and ventilation while still being cost-effective. It is perfect for applications where budget is a concern but breathability is still important.

Roof application:
polythylene polypropylene synthetic roof underlayment membrane  with logo is commonly used as waterproof underlay beneath the roof covering, which impervious to any wind driven rain or snow that gets blown through the roof covering, even when in direct contact with timber rafters and insulation.
Meanwhile as they are vapor permeable, allow the roof structure to breathe, so the moisture from leakage and condensation can escape, to avoid mold and rot of fiberglass or cellulose insulation, so won't lose its R-value due to heat-conducting moisture.
Wall application:
polythylene polypropylene synthetic roof underlayment membrane also can be used as house wrap, a wall underlay membrane which functions as a weather-resistant barrier, preventing rain from getting into the wall assembly meanwhile allowing water vapor to pass to the exterior.
They may also act as windproof layer (Air barrier), reducing air leakage through the building envelope, ensuring insulation materials maintain their thermal efficiency by minimizing air infiltration.
