Selection guide

  • Acoustic comfort

The advantages of the system

  • Aesthetic: exposed grid with off-set edge and hollow joint to absorb alignment deviations with the wall for a perfectly straight finish
  • Opening: open position with sliding panel in the plenum to not obstruct people's circulation
  • Acoustic: high correction, absorption coefficient αw up to 1 (NRC = 1)
  • Insulation: good air and noise tightness

Description


  • Sliding opening ceiling consisting of panels hung on an exposed profile fixed to the wall, forming a closed crevice joint with it
  • Self-supporting steel panels with continuous edges and sharp angles
  • The panels are equipped with a Z-hook-upturned edge (BRZC) at their ends to be flush with the framework
  • The edge profile consists of a take-up section to be fixed to the wall and a hook-up profile to be shifted and fixed under the flange of the take-up section according to the notch length of the panels. It allows the crevice joint thus formed to absorb alignment deviations with the wall
  • Optional acoustic enhancements

Bulk cut

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