VELUX Balcony Roof Windows - GDL

The VELUX CABRIO™ (GDL) is a balcony roof window that opens outward creating a roof balcony. The VELUX GDL CABRIO™ has the ability to transform above garage spaces, attics, and otherwise unused space into unique living space with the benefit of an outdoor balcony.


  • Adds sophistication to your space with extra light and a stunning floor-to-ceiling view
  • The GDL CABRIO roof window comes with a select wood frame and sash coated with a clear finish, and aluminum or copper cladding
  • The top sash opens for maximum ventilation and also pivots inward for easy cleaning from inside the room. The bottom sash opens outward to create a roof balcony
  • When the GDL CABRIO roof window is closed, a ventilation flap can be opened to provide a breath of fresh air, even if it is raining outside
  • A complete line of flashing systems help ensure a weathertight installation for your GDL roof window on most types of roofs: shingles/shakes and high profile roofing
  • Lower section comes with safety glass to reduce the risk of injury
  • Can be used as an emergency exit or rescue
