Application

For combination installations on roof pitches between 15–90°.

Description

Features and benefits:

  • Convenient operation – even with furniture placed beneath the window.
  • Easy to open and quick to close with the top control bar.
  • Additional fixed elements beneath offer a great view while standing and when seated.
  • Fixed elements are installed in combination side by side to create panoramic views. The fixed window is installed directly below the roof window.
  • 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 via the roof window.
  • One pull of top control bar allows background ventilation whilst the window remains securely closed. One further pull opens the window.
  • Rotates 180° and locks in place for ease of cleaning of the outer pane.
