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

Permavent APEX is a three-layer air open and vapour permeable membrane designed for pitched roofing and walling applications. It provides effective condensation control by allowing air and moisture vapour to escape while acting as a secondary barrier against water ingress. This untaped version is supplied without an integrated tape system, allowing flexibility where site-applied taping or alternative sealing methods are preferred. Manufactured by Permavent, APEX is suitable for use in non-ventilated cold and warm roof constructions.
