VELUX Twin and Combination Flashings 66x118cm EKN FK06 S0021E
Suitable applications and roof types
This flashing is engineered for use with compatible VELUX roof window and Sun Tunnel systems where a professional, weather-tight finish is required. The 660×1180mm format and recessed slate profile make it suitable for standard roof pitches in both new build installations and refurbishment projects. The flush-fitting design reduces visual impact and integrates neatly with slate roof coverings.

Installation and positioning
The flashing must be installed around the perimeter of the compatible roof window or Sun Tunnel opening to create a weather-tight seal. The recessed 8mm slate profile is engineered to sit flush with surrounding roof material, ensuring water runs off effectively and preventing pooling or penetration. Correct positioning is critical to maintain the weather-tight integrity of the installation.
- Install around the complete perimeter of the roof window or Sun Tunnel opening
- Ensure the recessed profile sits flush with surrounding slate material
- Position to allow water to run off effectively
- Follow VELUX installation guidance for your specific roof window model
Weather protection and maintenance
The flashing is engineered to deliver reliable long-term weather protection in typical UK roof conditions. The recessed design and weather-tight installation support effective water shedding and reduce the risk of water ingress. Regular inspection of the roof line, particularly after severe weather, will help ensure the flashing remains in good condition and continues to provide effective weather protection.
- Inspect regularly to ensure the flashing remains flush and undamaged
- Check after severe weather or high winds
- Keep the roof area clear of debris that could affect water run-off
- Maintain compatibility with your VELUX roof window system
