Installation and on-site handling
The aluminium profile construction requires careful handling to avoid damage during transport and storage on site. The anodised aluminium finish provides durability and weather resistance but should be protected from scratching during installation. Position the cover set around the window opening according to VELUX installation guidance, ensuring the top flashing section is correctly seated to direct water away from the window frame. The profile must be securely fixed to create a weather-tight seal and prevent wind-driven rain penetration. Ensure all fixings are appropriate for your roof structure and comply with building regulations for your region.
- Handle carefully to protect the anodised aluminium finish from scratching
- Position the top flashing section to direct water away from the window frame
- Secure the profile firmly to prevent movement and maintain weather-tight integrity
- Use fixings suitable for your specific roof construction type
Weather protection and maintenance
The anodised aluminium construction provides excellent weather resistance in UK roof conditions, and the included top flashing section ensures water is directed safely away from the window opening. Periodically inspect the cover set to ensure all fixings remain tight and the flashing is seated correctly, particularly after severe weather or high winds. Keep the profile clear of debris and moss growth, especially around the flashing section, to maintain effective water drainage. The anodised finish requires minimal maintenance but can be gently cleaned with mild soap and water if needed.
- Inspect fixings and flashing position regularly to maintain weather-tight performance
- Clear debris and moss growth to ensure effective water drainage
- Check the profile after severe weather to confirm it remains secure
- Clean gently with mild soap and water if the anodised finish requires attention
