Breather Membranes

Breather membranes are semi-permeable layers designed to allow water vapour to escape from within a building while preventing liquid water from entering. They're installed on the "cold" side of wall or roof structures to ensure buildings remain dry and condensation-free, protecting your investment from structural damage and insulation degradation.
