The CDM-CC Acoustic Suspension System is designed to optimise the sound insulation of suspended ceilings.

The system comprises of the CDM-CC hanger + the CDM-PROFILAT rail (either 45mm or 60mm wide) that clips into the hanger. There are 2 types available:
CDM-CC40 with the CDM-PROFILAT40 rail
CDM-CC60 with the CDM-PROFILAT60 rail

With CDM-CC suspension elements, sound insulation
improvements of more than 20 dB can be achieved.

Installation Guidelines

The hangers are mechanically fixed to the ceiling and then the CDMPROFILAT rail is snap fitted into the hangers. Plasterboard can then be fixed into the rails.

The minimum air void possible with this system is 45mm.

CDM-CC hangers must only be used with the CDM-PROFILAT rails (45mm/60mm) to ensure structural stability of the ceiling.

CDM-PERIMETERSTRIP must be used to isolate the suspended ceiling from surrounding walls to avoid undermining the acoustic integrity of the ceiling.
