Fixing and buying guide

What this product is and who it is for

This is a complete flashing and bracket assembly for installing VELUX roof windows into pitched tiled roofs. It is intended for roofers, builders, and experienced DIY installers undertaking roof window installations where weather-tight integration with the existing tile surface is essential. The single-unit configuration reduces on-site assembly time and minimises the risk of incomplete or misaligned installations.

Compatibility and sizing

The EDW FK08 2000 is engineered for compatible VELUX roof window systems. The flashing dimensions are 660 × 1400 mm, which accommodates standard roof window openings within this size range. Before ordering, confirm that your VELUX window model is compatible with the FK08 2000 flashing specification. Check the window manufacturer's documentation or consult your supplier if you are uncertain about compatibility.

• Designed for VELUX roof window systems only

• Verify window model compatibility before purchase
• Suitable for both new build and refurbishment applications

Pack contents and pre-installation checks

This is a single-unit package containing the profiled tile flashing and the integrated BDX 2000 bracket. Upon delivery, inspect the flashing for any damage to the aluminium profile or bracket assembly. Check that all edges are clean and free from burrs or deformation that could compromise the weather-tight seal. Ensure the roof opening dimensions match the flashing specification and that the surrounding roof structure is sound and level before installation begins.

• Single unit: flashing plus BDX 2000 bracket included
• Inspect for transport damage to aluminium profile and bracket
• Verify roof opening dimensions match 660 × 1400 mm specification
• Confirm roof structure is level and structurally sound

Installation and weather-tightness

The profiled design is engineered to integrate seamlessly with standard roof tiles, maintaining the integrity of the tiled surface whilst creating a weather-tight seal around the window opening. The BDX 2000 bracket provides secure fixing to the roof structure. Installation must follow VELUX guidance to ensure the flashing sits correctly and all joints are properly sealed. The grey finish is designed to blend with typical UK roof tile colours, reducing visual impact on the roof line.
