1.Breathable Membrane is a water resistant membrane but with high vapor permeability, use as diffusion open roofing felts under pitched roof tile or vapor permeable barrier house wraps 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".
