The VELUX Vapour Barrier (BBX) stops warm, moist air from your home from entering your roof construction. It’s quick and easy to install in your window frame, and creates an airtight seal to protect your roof from condensation and potential damage.
The edge of the BBX vapour barrier is specifically designed to fit tightly into the window frame rebate providing an air tight seal which will assist in meeting air pressure testing of the building.
