Product Application

The most common application for resilient bars is for use in soundproofing a ceiling or a wall. One of the most important things to remember is that to ensure maximum sound insulation performance, screws fixing the plasterboard must not be in contact with the joists. When installing a dual layer of boards, all joints in the second layer must be staggered in relation to those of the first layer.

Instructions for use

Resilient bars, as the name suggest act as the resilient layer that separates the mass of plasterboards from the rest of the surface that you are soundproofing. What is key to the success of any soundproofing work is that the weight you add should, where possible, be separated from the surface to be soundproofed by a resilient or springy layer.

In this case the light weight corrugated steel bars act as "springs" that allow the vibration and sound to be dissipated in a tiny movement. Resilient bars not only improve the impact characteristics but also the airborne characteristics of the surface you are soundproofing.

A rule of thumb would suggest that in a normal system where you are employing acoustic mineral wool, resilient bars and acoustic plasterboard, that the resilient bars will be doing about a third of the work from the airborne perspective and almost all the work form an impact perspective.

Where the resilient bar is to be fixed to metal studs, fix bar at 600mm vertical centres.  Fix the initial resilient bar 50mm down from the head of partition and the last bar 50mm from the floor.  Screw the resilient bars to the studs using 13mm wafer-head screws. Screw the plasterboard to the resilient bar only, ensuring the screw does not touch the metal substrate.  Bars are joined by butting together on the stud.
