High breathable waterproof membrane for roof underlay Housewrap,roofing Material Waterproof Breathable Underlay Membrane

Waterproof breathable membrane has excellent performance at water resistance, meanwhile with particular function of high vapor permeability, which mainly use used in construction as underlay on pitched roofs or walls.

It has three layers by Hot pressing composite technology:on the top and bottom is:polypropylene Spunbond non-woven fabric,between the two layers, is polyethylene material to form breathable film. 

The function of spunbonded nonwovens is mainly to enhance tension and hydrostatic pressure and protect the middle layer.

1) Breathable membrane with excellent complete waterproofing properties.

prevent the penetration of water from condensation or leaking in the covering.

2) High water vapor permeability.

3) Stable anti-UV & anti-aging performance.

4) 3-layers thermal laminated: PP+PE+PP.

5) Light weigth so easy handled.

6) Excellent tensile and tearing strength.

7) Good low temperature flexibility.

8) For both roof and wall application.

9)Stabilized, conforming to EU standards, resistant to UV radiation and excess temperatures.

10)Safe for environment and recyclable

11)not propagate fire.

12) High quality with very competitively price.

Waterproof breathable membrane can be used in roofing and wall application.

Roof application:

Breathable membrane 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:

Breathable 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.
