VELUX Installation Products

The range of Velux Installation Products acts as a second line in weatherproofing defense when fitting a roof window. Underfelt collars are available to protect against water ingress, while insulation collars further insulate your home reducing heat loss between the window and the roofing. Vapour barriers passively prevent warm air buildup and condensation from forming around the Velux roof window, which, if left unchecked, could mount up to a costly repair. While support trimmers fit between two closely installed roof windows to provide an improved internal finish and further support the windows.
