Celbar - Recycled Insulation

Typically used as the cavity filler in Walls or between floors either in conventional rigid construction or in isolated systems e.g. SonaCel for higher performance (see SonaCel product page). Celbar cavity fill insulation can either be sprayed into the cavity before the void is closed OR where a void is already closed it is blown by hose through holes to improve the acoustic insulation of walls and/or ceilings. When two layers of Plasterboard are used, the Celbar cavity fill insulation is blown in before the second layer is fitted. A simple wall construction of 63mm thick metal studs lined with 12mm plasterboard on each side was tested: [a] with no sound control material used - Result 31 STC [b] with mineral wool sound barrier batt - Result 33 STC [c] with 38mm of sprayed Celbar - Result 49 STC
