Collars

Designed to prevent condensation from forming in the roof construction and window frame, collars reinforce corners for extra security against perforation.

Providing exceptional insulation around roof window frames, collars can help to reduce heat loss and effectively eliminate low-temperature intrusion. We provide a wide choice of collars, all of which offer fast, easy and accurate assembly.
