Resilient Bar is a thin metal channel designed to substantially improve the sound insulation of plasterboard walls and ceilings. The channel effectively isolates the plasterboard from the studwork, eliminating 'direct contact' to dissipate sound which would normally be transferred through the frame. This system is easy to install and produces excellent results especially when used with suspended high mass ceilings.
Our resilient bars, or resilient channels as they are sometimes called, are superior quality and highly flexible unlike other types that are on the market which are just too rigid to have a beneficial effect. Do not be fooled by inferior, untested products that may simply look similar.
If installed correctly, Laboratory tests show that including Custom Audio Designs Robust Detail Approved Resilient Bars in a standard separating floor buildup
can increase airborne and impact reduction by ΔRw+Ctr 17dB and ΔLn,w 17dB respectively.
Even greater improvements in soundproofing can be gained by:-

Resilient Bar can easily be cut with tinsnips or hacksaw.
If fitted directly to the underside of an existing ceiling, 50mm battens should be screwed to the ceiling at approx. 600mm centres (depending on if you are using acoustic quilt or acoustic mineral wool), right angled to the joists. Care must be taken to ensure that the fixings used are secured to the joists and NOT just to the plasterboard. On walls the bars should be mounted at right angles to the frame max. 600mm centres, with the narrow mounting flange at the bottom and the wider flange at the top. This allows the plasterboard to draw itself away from the studwork.
A double layer of 12.5mm (or thicker) plasterboard, or similar
composite, should be used and fitted to within 5mm of the surrounding
walls/ceiling. Joints should be staggered in all direction.
Secure the first, or thickest layer, of plasterboard
to the resilient bars with the appropriate length drywall screws.
Flexible Mastic Sealant should be applied to ALL the edge perimeters after the installation of EACH layer to achieve optimum results.
All plasterbaord joints should be finished with traditional jointing methods and plaster skimmed before decorating.
|Dimensions:||Steel Guage : 0.5mm
Weight : approx. 0.37Kg/m
Length : 3 metres
|Performance:||When installed beneath an existing ceiling with 50mm acoustic mineral wool and 30mm
of plasterboard applied, improvements in both airborne noise and impact sound would normally be well in excess of
Fire resistance with a minimum of 30mm of plasterboard applied would be 1 hour.
