Product Description



Breathable and Waterproof Membrane for Pitched Roof Felt or Housewraps
Waterproof: Class W1
SD-value: 0.02m
Vapor permeable:


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), 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.


[Attentions for Construction]


·Construction shall not be carried out in rain, snow or over 5 degree wind weather;


·There shall be sufficient safety protective facilities in construction site, place firefighting devices according to stipulations.


Installation Sketch point


 Clean the substrate using broom or high pressure dusty cleaner.


Apply primer


Heat the membrane bottom using a high temperature flame gun.


Push forward while the primer and membrane oil melted


 Use a roller to push hard the membrane surface to ensure it stick firmly
