Window vapour barrier – usage
A window vapour barrier is a polyethylene vapour barrier collar that ensures proper insulation and air-tightness of window installations. The proper window vapour barrier is crucial for every successful window replacement project. It’s quick and easy to install in your roof window frame.
The edge of window vapour barrier fits tightly into the roof window frame rebate and creates an airtight seal to protect your roof from condensation and potential damage. After fitting the window vapour barrier in the window rebate, it is led to the interior ceiling/wall and connected to the vapour barrier of the roof/wall with supplied tape.
