Cleaning, service and maintenance


    Use of the ventilation flap
    To enjoy fresh air even when the window is fully closed, pull the control bar lightly downwards to open the ventilation flap. The window will remain locked, but air can enter the room through a built-in air filter.

    Opening and closing the window
    Pull the control bar once more to open the window. Friction springs in the hinges allow the sash to be parked in partially open positions. The window is closed by pushing upwards firmly on the control bar to lock the sash and close the ventilation flap.

    Ventilation position
    The built-in barrel bolt allows you to fix the window in an open position. The barrel bolt is placed in the top left part of the window, and slides into the bushing at the top of the side frame.

    Cleaning the pane
    To clean the outer pane, rotate the sash 180 degrees. The sash must be secured in position by sliding the barrel bolt into the bushing at the bottom of the side frame. This safety feature leaves both hands free for cleaning.

    Clean the pane with a soft, clean, lint-free cloth/chamois leather/nonabrasive sponge or a clean, non-metal window squeegee. Clean water will normally be sufficient for cleaning the pane. Ordinary, non-abrasive household cleaners can also be used. Soft water is best for cleaning panes. Therefore, in hard-water areas add a small amount of detergent to soften the water or wipe off all excess water after cleaning.



    • Avoid contact from silicone with the pane
    • Do not use any cleaning products containing abrasive particles
    • Do not use chemical products for cleaning the pane
    • Avoid contact with the pane from all sharp or abrasive objects including jewellery
    • Never attempt to clean off dirt on the pane without first applying water
    • If any works are taking place in the vicinity of the pane, protect the pane with a clean plastic sheet to prevent any splashes or staining from aggressive and abrasive compounds

    Minimising condensation
    Particularly in rooms with high levels of humidity, condensation can form on the inner pane of the window. This can be minimised by fitting a radiator directly below the window and by airing the room frequently.

    Cleaning the air filter
    The air filter can be removed and washed with ordinary household cleaners. Fully rotate and secure the window in cleaning position, then remove the filter from the filter rail. (New filters are available from VELUX).

    Cleaning the window
    The white polyurethane surface can be cleaned with ordinary household cleaners.

    Cleaning the flashing
    Leaves and other debris should be re moved from the flashing around the window once per year to allow rain water to flow freely.

    Snow and ice
    Remove snow and ice to allow melt water to drain off from and around the window.
