VELUX Vapour Barrier 94x160cm BBX PK10 0000
Suitable applications and installations
This vapour barrier collar is designed specifically for use with compatible VELUX roof window and Sun Tunnel systems. It is suitable for both new build construction and refurbishment work where you are installing or upgrading roof windows or Sun Tunnels. The collar creates a weather-tight seal around the perimeter of the installation, protecting the roof structure and interior spaces from moisture penetration. It is engineered to perform reliably in typical UK roof conditions, including exposure to rain, wind, and temperature fluctuations.

Installation and positioning
The vapour barrier collar must be installed as part of your roof window or Sun Tunnel system setup, working in conjunction with the compatible VELUX product. The collar is positioned to create a continuous seal between the window frame or tunnel and the roof structure, preventing water and moisture from penetrating the installation. Ensure the collar is properly aligned and secured according to the specifications of your chosen VELUX roof window or Sun Tunnel system. The 940 × 1600mm dimensions are designed to fit standard VELUX installations, but always verify compatibility with your specific product before installation.
- Install as part of complete VELUX roof window or Sun Tunnel system
- Position to create continuous seal around perimeter
- Align and secure according to VELUX system specifications
- Verify dimensions match your specific installation
- Ensure proper contact with roof structure for effective sealing
Professional finish and maintenance
The vapour barrier collar contributes to a professional, visually consistent roof finish that integrates seamlessly with your VELUX installation. Once properly installed, the collar requires minimal maintenance but should be inspected periodically to ensure the seal remains intact and effective. Check that the collar remains properly positioned and that there are no gaps or damage that could compromise the weather-tight performance. In refurbishment projects, the collar helps maintain the integrity of existing roof structures whilst upgrading to new daylight and ventilation solutions.
