VELUX EKW MK08 2002M 780mm X 1398mm Combi Flashing Element 2
Where to use this product
This combi flashing element is designed exclusively for MK08 VELUX roof windows installed on pitched roofs. It is positioned around the window aperture to manage water runoff and create a weathertight seal between the window frame and the roof structure. The product is suitable for standard pitched roof applications and should only be used with MK08 windows of the specified 780mm × 1398mm dimensions.
- MK08 roof window installations only
- Pitched roof applications
- New installations or window replacements
- Roofs with standard pitch angles
Installation and setup
The combi flashing element simplifies installation by combining upper and lower flashing components into a single assembly, reducing the number of separate components you need to handle and fit. Position the flashing element around the window aperture before securing the window frame. The integrated design ensures that both upper and lower sections work together to direct water away from the window and prevent ingress into the roof structure. Ensure the flashing sits flush against the roof surface and window frame to maintain the weathertight seal.
- Install before securing the window frame
- Position around the complete window aperture
- Ensure upper and lower sections align correctly
- Check for flush contact with roof and frame
- Secure according to VELUX installation instructions
Performance and maintenance
This combi element provides essential water management for your roof window installation. The integrated design ensures consistent weatherproofing performance by eliminating gaps between separate flashing components. After installation, periodically inspect the flashing seal, particularly after severe weather, to ensure it remains intact and properly seated. Clear any debris from around the flashing to maintain effective water drainage.
- Inspect flashing seal regularly for damage or movement
- Clear debris and leaves from around the flashing
- Check water drainage after heavy rainfall
- Ensure no gaps develop between flashing and roof surface
