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".
