VELUX BDX CK02 Insulation Collar Kit

Designed to exceed stricter building regulations by improving insulation performance of VELUX windows, the VELUX BDX 2000 kit contains both the high specification BDX insulation collar as well as a BFX underfelt collar and a traverse drainage channel.

Key aspects of the kit:

  • Helps projects achieve Part L Building Compliance.
  • Simple and easy to fit.
  • The BDX Collar insulates the window frame and reduces heat loss by preventing cold bridges.
  • The BFX Underfelt Collar provides a tighter fit and better water tightness between the window and your roof components.
  • The traverse drainage channel provides a secondary level of water protection against rainwater coming in from above the window.
  • Reduces condensation.

This kit is suitable for fitting with the VELUX EDL, EDZ and EDW roof flashings.
