Breather membranes

Glidevale Protect offers a complete range of external wall breather membranes ideal for offsite and volumetric construction projects. Our collection includes reflective, insulating membranes which are ideal to enhance the overall thermal performance of many wall types including timber frame, Structural Insulated Panels (SIPs), Cross Laminated Timber (CLT) panels and light gauge steel frame construction. Used on the cold side of the insulation, the membranes’ high vapour permeability combines with our air and vapour control layers on the warm side of the insulation to deliver full condensation control and the management of moisture within the wall cavity.
