Bottom-operated roof windows

From xxxx €

The sky is the limit with a bottom-operated roof window. Operated with an elegant handle at the bottom, VELUX bottom-operated roof windows give you a full, open view of your skyline and maximise the amount of natural daylight that can be allowed in. We recommend bottom-operated roof windows if you have to, or wish to, place your window in a high position, for instance in connection with a high knee wall.

Benefits

  • Enjoy panoramic views - while increasing your energy efficiency and natural ventilation
      
  • Convenient bottom operation - allows for installation on high knee walls 

  • Increase the amount of natural light in your rooms

    How to clean your window

    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. 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.
