If you want to create a watertight seals while insulating your VELUX extension element window, this BDX insulation collar and BFX underfelt collar are a perfect option to combine with the appropriate flashing.
The BDX insulation collar is an excellent solution for insulating around your roof window frame by reducing heat loss and eliminating cold bridges. Thanks to its flexible nature, it can be effortlessly compressed during the installation process. The combination of the foam's rigidity and flexibility ensures secure and energy-efficient construction within your roof.
Additionally, the BFX underfelt collar is ideal for ensuring a precise fit with a watertight seal between your windows, roofing underfelt and battens. Installation is easy as you can simply place it on top of your window and unfold. The self-supporting and adjustable drainage gutter effectively directs rainwater away from the top of your window in the case of a leak or broken tiles above.
