VELUX EDN 2500 Conservation Recessed Slate Flashing

The VELUX EDN 2500 Conservation Recessed Slate Flashing is ideal for conservation projects and historic buildings. Designed to fit a recessed roof window 40mm deeper into the roof structure, it reduces the window’s protrusion above the roofline while providing a sleek, streamlined finish. This single flashing is suitable for flat slate up to 8mm thick and works with roof pitches between 20° and 90°. The lacquered black aluminium finish complements traditional roofing aesthetics while ensuring long-lasting performance.
