Atrium Ridgelight 25-40°

Application

For commercial and public buildings. Suitable for a wide variety of circulation spaces, gallery spaces and small internal courts where people meet or pass in transit.

Description

The system consists of prefabricated modular skylights, including profiles, panes, flashings, control systems for natural and smoke ventilation and roller blinds.


Features and benefits:

  • Framing material ensures very low U-value.
  • Atrium roof glazing consists of multiple rows of ridge lights, supported only by structural beams, forming large glazed areas of identical looking venting and fixed units.
  • Complete daylight and ventilation control.
  • Superior environmental profile compared to aluminium rooflights.
  • Slim profiles and flush exterior surface provide an elegant appearance.
  • Integrated chain actuator creates an identical look for fixed and venting modules.
  • Internal blinds complete the interior with a 'free-floating' design.
  • A drainage gutter separates each strip. The design of the flashing allows for configurations with pitches between 25° and 40°.
