Breathable membranes

Breather membrane (or breathable membranes) are water resistant but air permeable. Typically they are used within external wall and roof constructions where the external cladding may not be completely water-tight or moisture resistant, such as in tiled roofs or framed wall constructions.

The membrane is located on the cold side of insulation and prevents moisture (as well as snow, wind, and contaminants such as dust) that may have been driven through the external cladding, from penetrating further into the structure. However, their air-permeability allows the structure to be ventilated, avoiding the build-up of interstitial condensation.

Any moisture that forms on the outside face of the membrane should be able to vent or drain to the outside.
