vapor permeable roof membrane / vapour permeable roof underlay / water vapor transmission / pitched roof underlay, roof breather


1), Introduction of Waterproof Breathable Membrane 


  1.     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
  2.     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. 
  3.     Breather membrane may also serve as an air barrier if it is sealed carefully at seams.
  4.     Breathable Membrane have good "water resistance", good "water vapor permeability", and good "air barrier properties".




2), Technical data of Breathabe Membrane 


  1. Products range: 80g,90g,100g,120g,140g,160g/m2.
  2. Roll size: 1.5m x 50m
  3. Water resistant : Class W1
  4. SD-value: 0.02m
  5. Vapor permeability: >2250g/m2/24h
  6. UV resistant: >3month
  7. Test to EN13859-1: Pass




3), Advantage of Breathable Membrane:


  1. CE mark available
  2. High quality with competitive price
  3. Excellent tensile and nail tear strength
  4. Good flexibility and ductility
  5. Light weight and thin, slip-resistant surface
  6. Simple handling and easy to use 
  7. Anti-ageing: both heat and UV stable


4), Performance of Breathable Membrane:  


     Resist liquid water passing through, but allow water vapour to pass through.

     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 :
