Home > Companies > VELUX Company Ltd > GPL manually operated, top-hung roof window, with GIL sloping fixed windows below, combination installation

Manually operated, top hung roof window with additional lower fixed element for combination installations on roof pitches between 15–55° (75° with special springs).

Fixed elements are installed in combination side by side to create panoramic views. The fixed windows are installed directly below the roof windows.

Combination flashings are modular meaning there is no limit to the overall size of the group, but the minimum distance between windows side by side is 100 mm.

Ventilation, exterior maintenance and cleaning is all via the roof window.

Features:

  • Top-hung window opens to any position up to 45° to allow panoramic, uninterrupted views.
  • Meets requirements for emergency escape.
  • Additional fixed elements beneath offer a great view while standing and when seated.

Operation:

  • The window is opened by means of a handle placed at the bottom sash.
  • Sash can also be rotated 180° and locks in place for the ease of cleaning of the outer pane.

Warranty:

  • Ten-year guarantee for windows and panes.
  • Three-year guarantee for electrical items and blinds.
