VELUX Insulation Collar 78x98cm BDX MK04 2000

Description

The VELUX Insulation Collar is designed to fit around the perimeter of loft insulation, creating a tight seal that prevents cold air infiltration and reduces heat loss through the roof. Sized at 78x98cm, it suits standard UK loft installations and is straightforward to fit during window installation or renovation work.

This fiberglass collar works as part of a complete insulation strategy, helping to maintain consistent internal temperatures and reduce energy consumption. By sealing the gap between the window frame and surrounding insulation, it minimises thermal bridging and draughts that can compromise loft performance.

The BDX MK04 2000 specification ensures compatibility with VELUX roof window installations. Proper installation of the insulation collar is essential for achieving the thermal performance of your loft space and supporting energy-efficient building practice.
