Permavent Apex Air Vapour Permeable Membrane (Taped) 1 x 50m

Permavent APEX is a three-layer air open and vapour permeable membrane designed for use in pitched roofing and walling applications. It provides condensation control by allowing air and moisture vapour to pass through the membrane while acting as a secondary barrier to water ingress. This version is supplied with an integrated double tape system to secure laps during installation. Manufactured by Permavent, APEX is suitable for use in non-ventilated cold and warm roof constructions and can be installed without the need for high or low level ventilation.
