VELUX EDN 1000 Recessed Slate Flashing with BFX Underfelt Collar

The VELUX EDN 1000 Recessed Slate Flashing with BFX Underfelt Collar is the ideal choice for homeowners seeking a sleek, streamlined finish for their VELUX roof window installation. Designed to sit 40mm deeper into the roof structure than a standard flashing, it provides a modern, low-profile appearance while ensuring superior weather protection and long-lasting durability.

Perfect for use with slates up to 8mm thick, as well as roofing felt and membranes, this recessed flashing guarantees a secure and watertight seal around your window. The included BFX underfelt collar further enhances weatherproofing performance by preventing moisture from penetrating between the roof material and window. Its corrosion-resistant aluminium construction ensures reliability and strength, while the grey finish complements the look of your VELUX window frame for a seamless integration.
