VELUX Centre-Pivot Roof Windows White Painted 78x98cm GGL MK04 2066
Installation and positioning
Install this window at a lower position than traditional roof windows to maximise your view and usability. The centre-pivot design means you can place furniture, beds, or desks directly underneath without obstruction. The top control bar operates smoothly from below, making the window accessible even when furniture is positioned close to it. Ensure the window is installed in a suitable roof pitch and that the surrounding structure is properly prepared to support the frame.
- Position lower than standard roof windows for seated viewing
- Leave adequate space around the frame for the sash to rotate fully
- Suitable for loft conversions, attic bedrooms, and study spaces
- Compatible with blind systems that click directly into pre-fitted channels
Operation and ventilation
The top control bar offers two operational modes. Push it to the ventilation position to allow fresh air circulation through a partially closed window, ideal for maintaining air quality without fully opening the sash. For full opening, continue operating the control bar to rotate the sash 180 degrees, which also provides safe access to the outer glass for cleaning from inside your home.
- Use ventilation position for controlled fresh air without full opening
- Rotate 180 degrees for complete access and outer glass cleaning
- Operation is smooth and easy, even with furniture nearby
- Removable and cleanable ventilation filter prevents dust and insects entering
Glazing features and maintenance
The window comes with premium glazing as standard, including safety lamination and toughened glass for durability and security. The glazing incorporates a UV filter to protect furnishings from fading, an antidew coating to reduce condensation, and specialised rain noise reduction to minimise sound during wet weather. The easy-clean coating on the glass simplifies maintenance. The removable ventilation filter should be checked regularly and cleaned to maintain effective air circulation and protect against dust and insect ingress.

Cleaning and safety
The 180-degree rotation capability makes external glass cleaning safe and convenient. You can fully access the outer surface from inside your home without needing external scaffolding or ladders. The white painted finish on the frame is durable and requires only occasional wiping with a damp cloth. The safety lamination in the glazing provides additional security and impact resistance, making it suitable for upper-floor installations where safety is a priority.
