VELUX Centre-Pivot Roof Windows White Painted 78x98cm GGL MK04 2070
Installation and positioning
Install this centre-pivot window in pitched roof applications where the top control bar can be easily reached from standing or seated positions. The lower installation height capability allows you to maintain an excellent view while seated, making it particularly suitable for bedrooms and work areas. Ensure the roof structure is prepared to the manufacturer's specifications and that flashing is correctly fitted to prevent water ingress. The white painted finish is factory-applied and ready for installation without additional preparation.
- Position the window lower than traditional models to maximise seated views
- Suitable for pitched roofs with standard rafter spacing
- Ensure adequate roof opening preparation before installation
- Check that the top control bar has clear access for daily operation
Daily operation and ventilation
Operate the window using the top control bar, which offers two distinct positions. For fresh air circulation without fully opening the window, use the ventilation position to crack the top open slightly. This allows air exchange while maintaining security and preventing rain ingress during light showers. For full opening and cleaning access, push the control bar further to rotate the window 180 degrees on its centre pivot, which brings the outer glass face inward for safe internal cleaning.
- Use ventilation position for controlled fresh air without full opening
- Rotate 180 degrees for complete outer glass cleaning from inside
- Operation is smooth even with furniture positioned directly below the window
- The removable ventilation filter should be checked regularly and cleaned to maintain airflow
Glazing performance and maintenance
The window features premium standard glazing with safety lamination, toughened glass, and an integrated UV filter. These elements provide durability, security, and protection from harmful ultraviolet radiation. The glazing also incorporates unique rain noise reduction technology, minimising sound during wet weather. The removable and cleanable ventilation filter protects your home from dust and insects while allowing continuous air circulation. Clean the filter regularly by removing it and rinsing or vacuuming as needed.
- Safety laminated and toughened glass provides security and impact resistance
- UV filter reduces fading of interior furnishings and fabrics
- Rain noise reduction technology minimises weather-related sound transmission
- Remove and clean the ventilation filter monthly or as dust accumulates
- Clean glass using standard window cleaning methods; the 180-degree rotation makes outer surfaces easily accessible
