VELUX Centre-Pivot Roof Windows White Painted 55x118cm GGL CK06 2066
What you get and key features
This window arrives as a complete unit with premium glazing as standard. The glass is toughened and laminated for safety, includes a UV filter, and features rain noise reduction technology. An antidew coating helps prevent condensation on the inner pane. The top control bar operates both the main opening and a separate ventilation position, so you can crack the window for fresh air without fully opening it. A removable ventilation filter is included to keep dust and insects out while allowing air circulation.
- Centre-pivot operation with 180-degree rotation for easy exterior cleaning
- Top control bar for intuitive operation and lower installation positioning
- Toughened, laminated, UV-filtered glazing with rain noise reduction
- Antidew coating on inner glass
- Removable and cleanable ventilation filter included
- Pre-fitted for quick blind installation using click-in system
Who this window suits
The GGL CK06 is ideal for loft conversions, attic bedrooms, and home offices where you want to position the window lower than traditional roof windows allow. The top-operated design means you can place furniture directly underneath without obstruction. It works well in properties where you need both daylighting and controllable ventilation, and the 180-degree cleaning rotation is particularly valuable for pitched roofs where external access is difficult or unsafe.
- Loft conversions and attic rooms with furniture placement constraints
- Properties where safe external window cleaning is a priority
- Homes requiring controlled ventilation without full opening
- Installations on pitched roofs between standard rafter spacings
Sizing and compatibility
The CK06 is a standard VELUX module size of 55x118cm. Check your roof structure before purchase to confirm rafter spacing and roof pitch compatibility. This window is designed to fit between common UK rafter centres. Verify the exact opening dimensions in your roof and compare against the product specifications. The white painted finish is a standard option; confirm this matches your interior décor requirements. Blinds can be added after installation using the pre-fitted click-in system.
- Size: 55x118cm (CK06 module)
- Confirm rafter spacing and roof pitch before ordering
- White painted finish – check against your interior scheme
- Compatible with VELUX blind systems via pre-fitted click rails
Before you install
Inspect the window on delivery for any transport damage to the frame or glazing. Check that the control bar operates smoothly and the pivot mechanism moves freely. Ensure your roof opening is accurately sized and that the surrounding structure is sound and properly weatherproofed. You will need appropriate flashing kit for your roof type and pitch – order this separately if not included. Have the installation area clear and ready, and confirm you have the correct tools and any additional fixings required for your specific roof construction.
- Inspect for delivery damage before installation
- Test the pivot and control bar operation
- Verify roof opening dimensions match the CK06 specification
- Order appropriate flashing kit for your roof type and pitch separately
