Resilient Bar Soundproofing

A vibration absorbing resilient corrugated steel bar used on timber studs and joists, for soundproofing walls and ceilings.

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.

Why the Resilient Bar?

Where you are constrained by space issues the choice of a resilient bar may be your only practical choice when soundproofing a ceiling or wall. With this solution you will lose just over an inch (35mm) from your original wall or ceiling. The resilient bar, or sound breaker bar works by decoupling the new suspended stud wall or ceiling from the joists. The new wall or ceiling is in effect floating off the stud or joists via lightweight corrugated steel bars. The sound is absorbed as it travels through the corrugated flange of the resilient bar.

How they work

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.absorbed as it travels through the corrugated flange of the resilient bar.

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.

Performance Upgrades

The use of resilient bars or acoustic hangers in ceiling constructions significantly improves the acoustic performance of a ceiling soundproofing project both from the impact and airborne perspective. We offer two upgrades to the basic ceiling; one is by adding Tecsound 50 membrane; and the second using 10mm SBx boards.

Tecsound 50 Membrane Upgrade

A very high performance acoustic membrane, it is flexible and improves both impact and airborne passage of sound. It is a high density polymer based synthetic soundproofing membrane providing excellent acoustic insulation in different construction elements. The product is fire resistant and self extinguishing.

SBx Board Upgrade

These boards are an excellent product designed to reduce the transmission of impact and airborne sound between two spaces. The product is our number one choice when trying to improve the soundproofing from noisy neighbours. SBx can be used for soundproofing walls, floors and ceilings whether constructed from timber, steel or solid substrate, in new builds, conversions, remedial and refurbishment projects.

In general we believe that the SBX board will improve performance by around 8-10 db over and above the stated figures in the comparison table. There is also an improvement in impact sound performance as well.

Solution Installation

The removal of an old ceiling sounds a little daunting but is in effect very easy to do. The only drawback is that it is a messy job. Resilience bars are attached to the joists perpendicular to the run of the joists at 400mm centres. Acoustic mineral wool is then placed up in between the joists. 

Finally a double layer of acoustic plasterboard is attached to the ceiling, the perimeter being sealed with acoustic mastic. Advice on finding a fitter is available on our Find a Fitter page.

More information.....

If you are adding recessed spotlights in this ceiling you will need to add an acoustic fire retardant light hood to each light, otherwise your soundproofing efforts will be severely compromised due to the hole you have created.

These acoustic spotlight hoods can be purchased from our on-line store.

When soundproofing a ceiling it is necessary to improve three basic components.

1. The mass of the ceiling - This is normally achieved by adding two layers of acoustic plasterboard and high density wool. The SBx upgrade further enhances this by the addition of even more resilient mass.

2. The resilience of the ceiling - This is the "springiness" of the ceiling. Without this, the addition of the mass will have very little impact. Resilient Bars offer a slim and cost effective method of achieving resilience. Leaving out the resilient layer will very materially reduce the performance of the soundproofing.

3. The sound "absorbency" of the ceiling - By adding different components the sound gets trapped more easily within the ceiling; here we prescribe the use of AMW60 100mm.

The total performance which is normally quoted on most sites refers to the performance of an average ceiling with soundproofing materials added.

We also give an indication of performance uplift. Remember that every 10dB of performance uplift corresponds to roughly a 50% improvement in the performance of the ceiling. So 20dB would indicate a 75% improvement over and above the original ceiling. refers to dB improvement when we compare any of our systems. This we hope is an informative way of telling the customer what kind of improvement they will get when they add a soundproofing system. Many competitor sites offer products that will boast much higher numbers. Be aware these are often referring to a complete system which include the original ceiling or floor. This often leads to confusion when trying to compare systems. We are an independent site and as such will try to sell only the most effective solutions available on the market today.
