Benefits of VELUX Roof Balcony

  • 1
    Panoramic views
    The VELUX Roof Balcony features a window that opens on its top hinges, allowing for extra headroom as you enjoy beautiful panoramic views. It requires a roof pitch of 35°- 53°.
  • 2
    Easy Operation
    The upper window is top-hung and opens outwards while the bottom section easily unfolds into a balcony with side railings.
  • 3
    The Balcony Roof Window features VELUX ThermoTechnology ™, an innovative combination of high-performance materials that provide excellent energy efficiency, insulation, and an airtight seal.
  • 4
    Natural ventilation
    The Balcony Roof Window features a unique top control bar that can be pulled once to allow fresh, filtered air to enter through the ventilation flap so you can enjoy fresh air without fully opening the balcony.
  • 5
    Simple maintenance
    To clean the outer pane, rotate the sash 180 degrees after securing it into position with the barrel bolt at the bottom of the frame. While the window is in the cleaning position, you can remove the air filter from the filter rail and wash it with ordinary household cleaners.
