Specifications of Vapour Permeable Roof Underlayment
vapour permeable roof underlayment, waterproofing foil, breathable membrane, vapor permeable, roof breathber
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.
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
UV resistant: >3month
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 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.
