Selection guide

  • Acoustic comfort

The advantages of the system

  • Aesthetic: hidden frame with offset edge and hollow joint to absorb wall alignment variations for a perfectly straight finish
  • Acoustic: high correction, absorption coefficient αw up to 1 (NRC = 1)
  • Opening: swing-down on both sides from below, ideal for crowded plenums
  • Plenum ventilation: open hollow joint suitable for hospital environments

Description

  • Swing-down opening ceiling composed of panels hooked on a concealed profile creating an open gap joint between the ends of the panels and the wall
  • Self-supporting steel panels with tight edges and sharp angles
  • The panels are equipped with notches at their ends for suspension on the framework and swinging to one side or the other
  • The concealed profile consists of a fixing section to be attached to the wall and a hooking profile to be shifted and fixed under the wing of the fixing section according to the length of the panel between notches. It allows the open gap joint thus formed to absorb alignment discrepancies with the wall
  • Acoustic enhancements as an option

Bulk cut

A gap A is required between the panel and the wall. Dimensions in mm.
