Security and glazing specification
This window is engineered with integrated frame locks, extra strong hinges, laminated internal glazing, and toughened external glazing to resist breakage and unauthorised entry. The 2-layer glazing system reduces heat loss and improves thermal comfort, helping to maintain room temperature and reduce condensation. These features make the GGL Q particularly suitable for ground-floor loft spaces or properties where enhanced security is a priority.

- Laminated internal glazing and toughened external glazing
- 2-layer glazing for improved insulation

Operation and ventilation
The top-operated centre-pivot mechanism allows you to open and close the window easily, even when furniture is positioned underneath. The control bar can be set to a ventilation position, allowing fresh air to circulate through a partially closed window without fully opening it. The window rotates 180 degrees, enabling you to clean the outer glass safely from inside without accessing the roof. A removable and cleanable ventilation filter protects your home from dust and insects during ventilation.

Pre-installation checks
Before purchasing, measure your roof opening carefully and confirm the rafter spacing matches the GGL UK08 requirements. Check that the roof pitch is suitable for centre-pivot operation and that there is adequate headroom below the window for safe operation. Verify that your roof structure can support the window's weight and that you have access to the outer glass for cleaning and maintenance. If you are replacing an existing window, check whether the new frame dimensions are compatible with your current opening.
