EC2 L heavy binCasettes

  • Product description
  • Features
  • Installation method


Heavy-duty containers for office floors and large partitioned spaces. EC2 L heavy-duty trays are self-supporting and rest on an exposed C-rail frame. The panels are fitted with an acoustic complex combining absorption (mineral wool) and insulation (plasterboard). These ceiling solutions prevent the transmission of noise between adjacent rooms. The panels, with sharp, abutting edges, have Z-shaped folds at each end to rest on the load-bearing profiles.
A safety fold is provided at the end to ensure that the panels remain firmly attached to the framework. The surface of the panels is flush with that of the supporting profiles. Technical equipment can be integrated by factory-cutting the complex.
