Breather Membranes

Home Shop Roofing Felt Breather Membranes

Breather membranes, also known as breathable membranes, allow insulated structures to quickly release excess moisture vapour into the atmosphere and keep the internal components of wall and roof structures dry whilst fulfilling the task of a secondary protection membrane and preventing penetration by external environmental impurities such as dirt and rain. These membrane types are installed on the cold or exterior side of the insulation beneath the main outer building lining, roof tiles or cladding.
