Weather Defence™

Weather Defence™; is a rigid air barrier used behind façade cladding systems to regulate the indoor environment. It has transformed building envelope construction and performance.

Weather Defence™; is an excellent air control barrier which helps to regulate the indoor environment by restricting heat gain or loss via uncontrolled air movement through the wall.

Follow the installation instructions in the Weather Defence™; manual to create a weathertight barrier that can be left exposed to the elements so work can continue on the interior.

With attention to detail, Weather Defence™; installations can achieve air tightness targets that contribute to a building’s energy efficiency and allow any glasswool insulation in the cavity to perform as intended by avoiding wind washing.
