1), Introduction of Waterproof Breathable Membrane
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 Breathabe Membrane
Products range: 80g,90g,100g,120g,140g,160g/m2.
Roll size: 1.5m x 50m
Water resistant : Class W1
Vapor permeability: >2250g/m2/24h

Test to EN13859-1: Pass
3), Advantage of 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 polypropylenenon-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 :
1, BREAWARF Breathable roofing felts / roofing membraneuse for the pitched roof tile underlay.
2, SHANQUAN Breathable housewrap use for the wood frame walls house shell
