Permavent Eco Breather Membrane 1m x 50m

Permavent uses the very latest technology from the medical industry to encapsulate the highest grade hydrophobic film inside the very highest quality spun-bond polypropylene layers. Unlike other companies, who simply stick the different layers together, Permavent membranes are manufactured in a single process that greatly improves the quality and integrity of our membranes. This 3 in 1 process means that Permavent offers the best performing breather membranes in their class with superior strength, breathability, flexibility and durability.

Permavent Eco is also fully certified under the CE having been tested and certified by independent European laboratories and is only manufactured under the strictest ISO requirements

Installing Permavent Eco

Permavent membranes must be installed the correct way up, with the Permavent logo printed side uppermost. For tile and slate roof applications the membrane should be laid horizontally across the rafters starting at the eaves and secured in place with either batten or membrane tape.

Permavent membranes should be installed at least 75mm up any wall or abutment and sealed in place using tape. Vent pipes, roof lights and apertures on the roof should also be sealed with tape and any nail tears or damage must be repaired.
