VELUX Centre-Pivot Roof Windows Pine 55x78cm GGL CK02 3070
What you get and compatibility
This is a centre-pivot roof window with a pine frame, pre-fitted with premium glazing including safety lamination, toughened glass, UV filter, and integrated rain noise reduction. The window comes with a removable and cleanable ventilation filter to protect against dust and insects. Pre-fitted brackets are included for quick and easy blind installation. The CK02 size (55x78cm) is a standard VELUX dimension; check your roof opening measurements carefully before ordering to ensure correct fit.
- Centre-pivot mechanism rotates 180 degrees for safe internal cleaning of outer glass
- Top control bar operates ventilation position independently of full opening
- Removable ventilation filter included
- Pre-fitted blind brackets for simple attachment
- Premium glazing with safety lamination, toughened glass, and UV filter as standard
Installation and preparation
Before installation, verify that your roof opening matches the CK02 dimensions (55x78cm) and that the surrounding timber structure is sound and square. The centre-pivot design and top control bar mean this window can be positioned lower than traditional top-hung models, so plan your installation height accordingly to maximise your view and accommodate furniture placement below. Ensure the roof pitch and flashing requirements are compatible with VELUX specifications for your roof type.
- Confirm roof opening size matches CK02 dimensions exactly
- Check roof structure is square and level before fitting
- Plan lower installation position to suit your sightlines and furniture layout
- Verify roof pitch compatibility with VELUX installation guidance
Operation and maintenance
The top control bar gives you two independent functions: open it to the ventilation position for fresh air without fully opening the window, or continue rotating to open the sash fully. The 180-degree rotation is a key feature for cleaning—simply rotate the window to access the outer glass safely from inside. The removable ventilation filter should be checked regularly and cleaned or replaced as needed to maintain airflow and protect against dust and insects. Blinds click directly into the pre-fitted brackets for tool-free installation.
- Top control bar operates ventilation mode separately from full opening
- Rotate 180 degrees to clean outer glass from inside safely
- Check and clean the removable ventilation filter regularly
- Click blinds into pre-fitted brackets without additional fixings
