The VT-CBC Crossbar Ceiling is a double frame ceiling system with click-on hangers and profiles designed to optimise the sound isolation of suspended ceilings. The system comprises of VT-CBC hangers, click-on crossbars (UD274007) and C-profile rails (CD5027). Depending on required resonance frequency the VT-CBC hangers can be delivered with Regufoam pads in thickness 25 mm, 37 mm or 50 mm.

Installation Guidelines
The hangers are mechanically fixed via threaded rod to the ceiling with c/c-distances G and P and clicked into the crossbars. Secondary profiles with c/c-distance S are clicked onto the crossbars. Plasterboard can then be fixed on to the rails. A self adhesive elastic strip VC1001 should be used to isolate the suspended ceiling from surrounding walls to avoid acoustic bridging between ceiling and wall. Mineral wool should be used in the air void to absorb possible standing waves in the void.
