The Wraptite External Air Tightness Barrier is a self-adhesive vapour permeable air tightness membrane designed to be installed outside the services zone, which reduces the chance of potential penetrations to the air barrier. Lightweight and easy to install, Wraptite can also be used to create a full wall and roof airtight envelope. The self-adhered backing not only ensures an airtight seal but resistance at laps against water penetration, dust, air infiltration and wind resistance.

Thanks to being fully self-adhered, Wraptite can stick to a variety of substrates including concrete, steel and sheathing boards without the use of primer.
