VELUX Underfelt Collar and Transverse Drainage Gutter.
The BFX Underfelt Collar ensures a fast connection between the VELUX
Roof Window and the roofing felt/membrane. It helps to protect against
drafts and wind driven rain and snow around the window installation.
It comes as one piece making fitting easy, especially around the window corners.
The tranverse drainage gutter included also prevents any
water ingress around the roof opening caused by missing or broken slates
or tiles above the window.
