VELUX Centre-Pivot Roof Windows White Painted 94x160cm GGL PK10 2070Q
Typical applications and installation
This centre-pivot roof window is commonly installed in loft conversions, attic bedrooms, home offices, and upper-storey rooms requiring both daylight and security. The 94x160cm size suits standard rafter spacings in UK residential properties. Installation should be carried out by a qualified installer to ensure proper flashing, weatherproofing, and structural support. The window must be fitted with appropriate roof flashing kits to prevent water ingress and maintain building regulation compliance. Ensure the opening in the roof structure is correctly sized and that surrounding timber is sound before installation.
- Suitable for loft conversions, attic rooms, and upper-floor spaces
- Requires professional installation with appropriate roof flashing
- Check rafter spacing and roof structure before ordering
- Verify building regulation requirements for your local authority
Operation and ventilation
The window is operated via a top control bar that can be positioned for full opening or adjusted to a ventilation setting, allowing fresh air circulation through a partially closed window. This feature is particularly useful in bedrooms and living spaces where controlled ventilation without full opening is desired. The centre-pivot design means the window rotates 180 degrees, enabling you to safely clean the external glass from inside without accessing the roof. The removable and cleanable ventilation filter should be checked regularly and cleaned or replaced as needed to maintain airflow and protect against dust and insect ingress.
- Operate top control bar for full opening or ventilation-only position
- Rotate window 180 degrees for safe internal cleaning of outer glass
- Check and clean ventilation filter regularly to maintain airflow
- Window can be opened even with furniture positioned underneath
Security features and maintenance
The GGL Q model incorporates multiple security enhancements: integrated frame locks, extra-strong hinges, laminated internal glazing, and toughened external glazing work together to resist forced entry and accidental breakage. These features make the window particularly suitable for properties at higher risk of break-ins or where security is a key concern. Maintenance is straightforward: regularly inspect the frame locks and hinges for any signs of wear, clean the glazing using standard window cleaning methods, and ensure the ventilation filter is kept clear. The laminated internal glazing will remain intact even if the external toughened glass is damaged, providing continued security and safety.
- Integrated frame locks and reinforced hinges provide burglary resistance
- Laminated internal glazing and toughened external glazing resist breakage
- Inspect locks and hinges periodically for wear
- Clean glazing regularly; laminated inner layer provides safety if outer glass breaks
Thermal performance and blind compatibility
The 2-layer glazing system reduces heat loss through the window, contributing to improved thermal efficiency and indoor comfort in converted or newly built spaces. This helps reduce heating costs and maintains more consistent room temperatures. The window comes with pre-fitted brackets that allow blinds to be quickly and easily clicked into place, providing light control and additional thermal insulation when required. Choose blinds appropriate for roof windows to ensure they do not obstruct ventilation or interfere with the window's operation.
