Operation and installation positioning
The centre-pivot design with top control bar is the defining feature of this window. You can open the top control bar to a ventilation position to allow fresh air circulation through a closed window, ideal for background ventilation without full opening. The 180-degree rotation capability makes external glass cleaning safe and easy from inside. Because the operating mechanism is at the top, you can install this window at a lower height than top-hung alternatives, giving you a better view and making the window accessible even when seated. This design also means you can place furniture directly underneath without obstruction.
- Top control bar for ventilation position and full opening
- 180-degree rotation for safe external glass cleaning from inside
- Lower installation position possible due to top-operated design
- No obstruction to furniture placement below the window
Pre-installation checks and compatibility
Before ordering, confirm your roof opening dimensions match the CK02 size code (55x78cm). Check that your roof pitch and structure are suitable for a centre-pivot window installation. Verify that the lower installation position this window allows suits your room layout and sightline requirements. Confirm you have adequate headroom above the window for the top control bar operation. If you plan to add blinds, note that this model has a pre-fitted click-in system for quick installation without additional fixings.
