Roof Access Windows

GXU
VELUX Roof Access Window provides easy roof access for repairs, maintenance, or emergency and egress. A convenient locking device keeps the sash in its open position, and it also features a ventilation flap for when roof access isn't necessary. With a slim sash and frame appearance, it looks sleek against any roofline and can be installed as a left-hinged or right-hinged window.

  • Suitable for 15° to 85° roof pitch
