How and where to use guide
VELUX Vapour Barrier 114x118cm BBX SK06 0000
Typical applications and compatibility
This vapour barrier collar is specifically engineered for use with VELUX roof window and Sun Tunnel systems in the SK06 size range. It is suitable for installation in both new build construction and refurbishment work where roof windows or Sun Tunnels are being fitted. The collar forms part of the weather-tight seal system around the window opening and should be used as part of the complete VELUX installation package for your specific window model.
- New build roof window installations
- Refurbishment and retrofit projects
- VELUX Sun Tunnel installations
- Pitched roof applications in UK climate conditions
Installation and positioning
The vapour barrier collar must be installed around the window opening to create a continuous weather-tight seal. It should be positioned as part of the window installation sequence, typically after the window frame is secured but before final roof covering is applied. The collar works in conjunction with other VELUX sealing components to ensure moisture cannot penetrate around the opening. Always refer to the specific installation instructions provided with your VELUX window system, as correct positioning is critical to performance.
- Install as part of the complete VELUX window system
- Ensure the collar sits flush around the entire opening perimeter
- Check compatibility with your specific VELUX window model before installation
- Coordinate installation timing with roof covering application
Performance and maintenance
The vapour barrier collar is engineered to maintain weather-tight performance in typical UK roof conditions, including exposure to rain, wind, and temperature variations. Once correctly installed, the collar requires no special maintenance. However, you should periodically inspect the seal around the window opening, particularly after severe weather, to ensure it remains intact and free from damage. Any gaps or damage to the collar should be addressed promptly to prevent moisture ingress.
- Designed for reliable performance in UK weather conditions
- Inspect seal integrity periodically, especially after storms
- Keep the collar and surrounding area clean and free from debris
- Address any visible damage or gaps immediately to prevent water ingress
Important limitations and on-site tips
This vapour barrier collar is designed specifically for VELUX roof window and Sun Tunnel systems and must not be used with other window manufacturers' products. The collar is sized at 1140 × 1180mm and is compatible only with SK06 VELUX systems; using an incorrectly sized collar will compromise the weather-tight seal. Always verify product compatibility before ordering and installation. The collar works as part of a complete sealing system; it should not be relied upon as a standalone weather protection measure.
- Confirm SK06 compatibility with your VELUX window model before purchase
- Do not attempt to use with non-VELUX window systems
- The collar is one component of a complete sealing system
- Store in dry conditions before installation to prevent damage
