Description

The VELUX Insulation Collar is a fibre-reinforced plastic collar designed to fit CK06 roof windows and create a thermal seal around the timber frame opening. It prevents heat loss by forming a tight barrier between the window frame and surrounding insulation materials such as fibre batts or cellulose. The collar's compact design allows straightforward installation in new builds, renovations, and loft conversions. Measuring 55×118cm, it suits standard timber frame openings and works with typical loft insulation depths to maintain building performance.
