waterproof breathable roof underlayment housewrap

 

Product Description

   Breathable membranes have 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.

 

    Bbreathable membranes are 3layers thermo-bonded: PP non-woven fabric of top and bottom layer for protection and reinforcement; Micro-porous PE film, between the two layers, is to form breathable membrane. They are polyolefin products that can easily be recycled and can even be categorized as a normal household waste.

 

 

 

Advantages

1) Breathable membrane with excellent waterproofing properties.

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) High quality with very competitively price.

Applications

Roof application:

     Breathable membranes are commonly use 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 membranes can use 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

 

 breathable membranes contain special stabilization additives which extend their resistance to UV radiation to 3 months, so can also use as a temporary waterproof barrier during the construction process, but we recommend that the covering finish should be quickly applied.
