- Breathable Membrane is a water resistant membrane but with high vapour permeability, use as diffusion open roofing felts under pitched roof tile or vapour permeable barrier housewraps on timber frame walls
- Breather membrane functions as a weather-resistant barrier, preventing rain from getting into the roof or wall assembly while allowing water vapor to pass to the exterior.
- Breather membrane may also serve as an air barrier if it is sealed carefully at seams.
- Breathable Membrane have good "water resistance", good "water vapor permeability", and good "air barrier properties".
2), Technical data of SHANQUAN Breathabe Membrane

3), Advantage of SHANQUAN Breathable Membrane:
- CE mark available
- High quality with competitive price
- Excellent tensile and nail tear strength
- Good flexibility and ductility
- Light weight and thin, slip-resistant surface
- Simple handling and easy to use
- Anti-ageing: both heat and UV stable
4), Performance of Breathable Membrane:
Resist liquid water passing through, but allow water vapour to pass through.
5), Structure of Breathable Membrane:
All SHANQUAN vapour permeable membranes are 3 layers thermal laminated:
PP non-woven fabric + PE fuctional film + PP non-woven fabric
Spun-bonded polypropylene non-woven fabric layers for protection and reinforcement.
Micro-porous polyethylene film is the functional layer which is water-resistant but allow water vapour to pass through.
6), Applications of Breathable Membrane :
- BREAWARF Breathable roofing felts / roofing membrane use for the pitched roof tile underlay.
- SHANQUAN Breathable housewrap use for the wood frame walls house shell
