VELUX Recessed Flashings W/ Installation Productions 94x140cm EDN PK08 2000
Suitable applications and roof types
This flashing kit is engineered for pitched roof installations and works with standard roof coverings typical in UK construction. The recessed design is particularly effective where a flush, professional appearance is important and where the window needs to integrate seamlessly with the existing or new roof plane. The system is equally suitable for new build projects and refurbishment work, making it a versatile choice for both renovation of older properties and modern construction.
- Pitched roof installations only
- Suitable for new build and refurbishment projects
- Designed for UK roof conditions and weather exposure
- Creates flush, professional roof finish
Installation and setup
The BDX 2000F installation frame forms the foundation of this system and must be correctly positioned before the window is fitted. The 8mm slate flashing is integrated into the frame to create the weather-tight seal. Installation should follow VELUX guidance to ensure the window sits properly flush with the roof plane and the flashing creates an effective barrier against water ingress. Correct positioning of the frame and flashing is critical to the long-term performance of the installation, particularly in exposed UK roof conditions where wind-driven rain is common.
- Install BDX 2000F frame first, ensuring level and secure positioning
- Integrate 8mm slate flashing according to VELUX installation instructions
- Ensure window sits flush with roof plane for professional appearance
- Verify weather-tight seal before completing roof covering
Maintenance and durability
The recessed flashing system is engineered for long-term durability in typical UK roof conditions. The 8mm slate flashing provides robust weather protection and the complete kit is designed to perform reliably without regular maintenance beyond standard roof inspections. Periodically check that the flashing remains secure and that no debris has accumulated around the window frame, particularly in autumn when leaf fall is heavy. The flush installation means the window integrates with the roof plane, so ensure the surrounding roof covering remains in good condition to support the overall weather-tightness of the system.
- Inspect flashing annually as part of routine roof maintenance
- Clear debris from around the window frame, especially in autumn
- Check that flashing remains secure and properly sealed
- Maintain surrounding roof covering to support weather-tightness
Limitations and important considerations
This kit is specifically designed for PK08 windows at 940×1400mm and must not be used with other window sizes or types. The recessed installation method requires pitched roof applications and is not suitable for flat roofs. The system is engineered for typical UK roof conditions but performance depends on correct installation and proper maintenance of the surrounding roof covering. Always follow VELUX installation instructions to ensure the warranty remains valid and the weather-tight performance is achieved.
