More Information
Permavent 1m x 50m Apex Breather Membrane is a 3 layer breather membrane for use as a pitched roof underlay. It is a vapour and air permeable membrane providing unique condensation control which eliminates the need for low or high level ventilation. Permavent APEX also provides a secondary barrier to water ingress. Permavent Apex vapour permeability helps to reduce the condensation within the roof structure, whilst protecting it from the rain and wind outside.
