Air Permeable Breather Membrane

Air permeable breather membranes help to reduce the build up of condensation within roof structures. They allow both air and water vapour to pass through, meaning a vapour control layer isn’t required at ceiling level. You’ll find products from industry-leading brands KLOBER, POWERLON and Cromar in this range.

Although air permeable breather membranes allow water vapour to pass through, they also act as a secondary barrier to the ingress of rain, wind and snow. This type of membrane has been developed to be tear-resistant with strong tensile strength, and long lasting to match the life of the roof construction.

Air permeable breather membranes are installed onto the outer side of the insulation. To make sure they function correctly and also act as a secondary waterproofing layer, it’s important to ensure all membrane joints are fully sealed with heavy-duty tape. Additionally, this will also help to prevent air leakage. For more advice, give our customer service team a ring on 01752 692 206.
