Operation and daily use
The top control bar is the key to this window's flexibility. Push it to the ventilation position to allow fresh air circulation through a closed window, ideal for controlled indoor air quality without full opening. The centre-pivot mechanism lets you rotate the entire window 180 degrees, which is essential for safely cleaning the outer glass from inside without ladders or external access. The design means you can operate the window fully even when furniture is positioned directly underneath, unlike traditional top-hung windows.

- 180-degree rotation for safe internal cleaning of exterior glass
- Operates smoothly with furniture placed underneath
- Removable filter can be cleaned regularly to maintain ventilation efficiency
Pre-installation checks
Before purchasing, measure your roof opening carefully to confirm it matches the 78x140cm specification. Check that your roof pitch is within the installation range for this model. Inspect the roof structure around the opening to ensure it is sound and can support the window weight. Verify that the internal ceiling height and room layout will accommodate the lower positioning that this window allows. Ensure you have adequate access for installation and that the pine finish is suitable for your interior décor.
