Who this is for and key benefits
This window suits homeowners and builders who want flexible furniture placement beneath the window. The top control bar design lets you position the window lower than traditional models, giving excellent views whether standing or seated. The ventilation position allows fresh air without fully opening the window, and the 180-degree rotation removes the need for external access equipment for cleaning.
- Ideal for rooms where you want to place furniture directly under the window
- Top control bar enables lower installation for better sightlines
- Ventilation position provides air circulation without full opening
- Safe external glass cleaning from inside the room
- Dust and insect protection via removable filter
Pre-installation checks and preparation
Before ordering, confirm your roof opening matches the FK08 size of 660 x 1400 mm. Check that your roof pitch is within VELUX's specified range for this model. Ensure the opening is square and level, and that the surrounding roof structure is sound and able to support the window weight. You will need the appropriate VELUX flashing kit for your roof covering type (tiles, slates, or metal). Have the ventilation filter location accessible for future cleaning and replacement.
- Verify roof opening dimensions: 660 x 1400 mm
- Check roof pitch compatibility with VELUX specifications
- Confirm roof structure is level, square, and structurally sound
- Order the correct flashing kit for your roof covering material
- Plan access to the ventilation filter for maintenance
Installation and operation
Installation should be carried out by a qualified roofer or surveyor to ensure weathertightness and safety. The window operates via the top control bar: push upward to open fully, or pull to the ventilation position for fresh air without full opening. To clean the outer glass, rotate the window 180 degrees and clean from inside. The removable ventilation filter should be checked and cleaned regularly to maintain airflow and protect against dust and insects. VELUX blinds can be installed quickly by clicking them into the pre-fitted brackets.
