VELUX Centre-Pivot Roof Windows White Painted 134x140cm GGL UK08 2070
Who this window is for
This window suits homeowners and builders installing roof windows in properties where space is at a premium and furniture placement flexibility is important. The top control bar operation makes it accessible even when wardrobes, beds or other furniture are positioned directly underneath. It is particularly popular in loft conversions, attic bedrooms and home offices where natural light and ventilation are needed but traditional side-hung windows are impractical.
- Ideal for rooms with limited floor space or fixed furniture layouts
- Suitable for both new builds and retrofit installations
- Works well in residential properties where ease of use is a priority
Key features and operation
The window operates via a top control bar that you can open to a ventilation position, allowing fresh air circulation through a partially closed window. The centre-pivot mechanism means the entire sash rotates 180 degrees, which is essential for safely cleaning the outer glass pane from inside without needing external access equipment. The glazing package includes safety lamination for security, toughened glass for durability, a UV filter to reduce fading of interior furnishings, and acoustic treatment to minimise rain noise. A removable and cleanable ventilation filter is included to protect against dust and insects during ventilation.
- Top control bar for ventilation without full opening
- 180-degree rotation for interior cleaning of exterior glass
- Premium glazing with safety lamination and toughened glass
- Removable ventilation filter included
- Pre-fitted brackets for quick blind installation
Sizing and compatibility
This window is sized at 134x140cm, which is the UK08 standard roof window dimension. Before purchasing, confirm that your roof opening matches this size or can be adapted to it. The window is finished in white paint, so check that this colour coordinates with your interior décor and existing joinery. The pre-fitted blind brackets mean you can quickly add optional blinds without additional fixings or installation steps.

Pre-installation checks and preparation
Before fitting, ensure your roof structure can accommodate a 134x140cm opening and that the surrounding timber framing is sound and level. Check that the roof pitch is suitable for roof window installation and that there is adequate headroom above the window for safe operation of the top control bar. Inspect the area for any existing leaks, damp or structural issues that should be resolved before installation. Have your flashing kit and any required adapters ready, as these are typically ordered separately. Plan your installation to allow proper sealing and weatherproofing around the window frame.
