Resilient bar is a thin metal channel designed to substantially improve the sound insulation of plasterboard walls and ceilings. Our resilient bars are Robust Detail approved and tested. Do not be fooled by inferior, untested products that may simply look similar.

Resilient bars effectively isolates the plasterboard from the studwork, eliminating 'direct contact' and thus dissipating sound which would normally be transferred through the frame. resilient bars are easy to install and produces dramatic results especially when trying to reduce impact noise through floors.

Our resilient bars, or resilient channels as they are sometimes called, are superior quality and highly flexible unlike other types on the market which are just too rigid to have a beneficial effect.

For example:
If installed correctly, laboratory tests show that including Custom Audio Designs' Robust Detail Approved resilient bars in a standard separating floor build-up can increase airborne and impact reduction by ΔRw+Ctr17dB and ΔLn,w17dB respectively.
