VELUX Centre-Pivot Roof Windows White Painted 94x140cm GGL PK08 2070
What is included and what you need to know
This is a complete roof window unit with white painted timber frame. The glazing is factory-fitted with laminated safety glass, toughened outer pane, UV filter, and rain noise reduction technology as standard. The window features a removable and cleanable ventilation filter to protect against dust and insects during ventilation. Pre-fitted brackets are included to allow quick installation of optional VELUX blinds by simple click-fit attachment. The centre-pivot mechanism with top control bar is the defining feature: it opens from the centre point, rotates fully 180 degrees for cleaning access, and can be set to a ventilation position without full opening.

Compatibility and installation considerations
The GGL PK08 2070 is designed for pitched roof installations at angles typically between 15 and 90 degrees. The centre-pivot design and top control bar make this window particularly suitable for rooms where you want to position the window lower than standard, or where you plan to place furniture underneath. The 180-degree rotation capability means you can safely clean the external glass from inside without needing external access equipment. Before ordering, confirm your roof pitch and the exact opening dimensions required in your roof structure. This window requires proper flashing and weatherproofing during installation to prevent water ingress.
- Suitable for pitched roofs between 15 and 90 degrees
- Centre-pivot operation allows lower installation positions
- Full 180-degree rotation enables internal cleaning of outer glass
- Allows furniture placement directly beneath the window
- Requires appropriate flashing kit for your roof type (sold separately)
Pre-installation checks and preparation
Before fitting, measure your roof opening carefully to confirm it matches the PK08 size specification (94x140cm). Check that your roof pitch falls within the recommended range and that the surrounding roof structure is sound and properly supported. Ensure you have the correct flashing kit for your specific roof covering type, as this is essential for weatherproofing and is not included with the window. Inspect the window on delivery for any transport damage. The frame should be stored flat and protected from weather until installation. Have the installation instructions to hand before beginning work, as centre-pivot windows require specific fixing procedures to ensure the pivot mechanism operates correctly.
- Verify roof opening dimensions match PK08 specification
- Confirm roof pitch is within 15 to 90 degrees
- Obtain the correct flashing kit for your roof covering type
- Inspect for transport damage on delivery
- Store flat and protected until ready to install
- Review installation instructions for pivot mechanism setup
Operation and maintenance
The top control bar is your main operating point. Push it outward to open the window fully, or hold it in the intermediate position for ventilation without full opening. The 180-degree rotation is achieved by continuing to push the control bar until the sash rotates completely, giving you safe access to clean the outer glass from inside. The removable ventilation filter should be checked regularly and cleaned or replaced as needed to maintain airflow and protect against dust and insect ingress. The laminated and toughened glazing requires only standard window cleaning; the safety features mean the glass will not shatter if broken. Ensure the pivot points and control bar mechanism remain clean and free from debris for smooth operation.
- Top control bar: push outward to open, intermediate position for ventilation
- Rotate 180 degrees for safe external glass cleaning from inside
- Check and clean ventilation filter regularly
- Clean glazing with standard window cleaning methods
- Keep pivot mechanism and control bar free from debris
