Breather Membranes for use externally

External

A Breather Membrane is designed to be fitted to the external (cold) side of a build-up. The Breathable Membrane is waterproof against wind, rain and snow, but also vapour-permeable which allows the passage of water vapour or moisture through the membrane. The benefit to this is when installed in a build-up in conjunction with an internal VCL (Vapour Control layer), it helps control the movement of moisture through the structure from the inside to the outside which can avoid potential condensation issues.
