How and where to use guide
VELUX Centre-Pivot Roof Windows White Painted 55x78cm GGL CK02 2066
Typical applications and positioning
Install this centre-pivot window in pitched roof spaces where you need to maximise usable floor area beneath the window. The top-operated design allows you to position the window lower than traditional roof windows, giving excellent views whether standing or seated. This makes it particularly suitable for bedrooms, home offices, and living spaces in loft conversions. The 55x78cm size (CK02) fits standard rafter spacings and suits rooms where you want natural light without sacrificing furniture placement flexibility.
- Position lower on the roof slope to optimise sightlines from seated positions
- Ideal for rooms where wardrobes, desks, or beds will be placed directly underneath
- Suitable for pitched roofs with rafter centres of 600mm or 1200mm spacing
- Install in bedrooms, home offices, and living areas requiring both light and usable wall space
Operation and ventilation
The top control bar provides two operating positions. Push the bar to the ventilation position to allow fresh air circulation through a closed window, useful for moisture control and air quality without full opening. For complete opening, continue rotating the sash to the fully open position. The centre-pivot design allows the window to rotate a full 180 degrees, which is essential for safe external glass cleaning from inside your home.
- Use ventilation position for steady air flow without full window opening
- Rotate 180 degrees for safe access to external glass surfaces from indoors
- Operation remains smooth even with furniture positioned directly below
- Top control bar is accessible and easy to operate for all users
Cleaning and maintenance
The premium glazing package includes an easy-clean coating that reduces dirt adhesion and simplifies maintenance. The removable and cleanable ventilation filter protects your home from dust and insects whilst allowing air circulation. Clean or replace this filter regularly, particularly in dusty environments or during high pollen seasons. The 180-degree rotation feature allows you to safely clean the external glass from inside without accessing the roof.
- Use the easy-clean coating with warm water and soft cloth for routine cleaning
- Remove and clean the ventilation filter monthly or as required
- Rotate window 180 degrees to access and clean external glass safely from indoors
- Check seals and drainage channels seasonally to maintain weathertightness
Safety features and glazing specification
The window comes with premium safety lamination and toughened glass as standard, providing impact resistance and security. The integrated UV filter protects furnishings and reduces glare, whilst the antidew coating minimises condensation on the inner surface. Unique rain noise reduction technology keeps the room quieter during wet weather. These features are factory-fitted and require no additional specification or installation steps.
