Selection guide

  • Acoustic comfort

The advantages of the system

  • Aesthetic: rails and panels are flush at the same level; no drilling of the C carrier rail thanks to the fixing of partition heads with hammer head screws
  • Acoustic: high correction, absorption coefficient αw up to 1 (NRC = 1)
  • Dimension: choice of different rail and panel widths. The length of a self-supporting panel is adaptable to the facade grid
  • Installation: simple and secure with Z-shaped hook-up panels (BRZC) to prevent any panel falls when the ceiling grid is fully open
  • Access: easily removable with wide access to the plenum

Description

  • Closed suspended ceiling made up of self-supporting panels placed on exposed C rail carriers with a flat or stepped joint
  • Self-supporting panels with flush edges and sharp angles
  • The panels have Z-hooked edges (BRZC) at their ends to be flush with the framework
  • The BRZC edges make it easy to slide the panel onto the framework during installation, facilitating the filling of each bay while preventing them from disconnecting from the supporting framework, installed without primary connecting frameworks cluttering the plenums
  • The aluminum C rail with a stepped joint allows for a hammer head screw to be slid in, avoiding any drilling when fixing partition heads
  • Acoustic additions as an option
  • Hook-on version to the framework in an open position available upon request
