Resilient Bars- Soundproofing Ceilings with minimal height loss

Where you are constrained by height issues the choice of a resilient bar ceiling maybe your only practical choice when soundproofing a ceiling. With this solution will lose just over an inch ( 35mm) from your original ceiling height.

Additional info on acoustic membranes and ceilings

Where a customer wants to further enhance the airborne soundproofing on a ceiling they can add an acoustic membrane between layers of plasterboard or stapled directly to the joist. When working on the ceiling this can be tricky to do in practice. Two types of membrane are available the Tecsound membrane and a lighter Acoustic membrane. On balance it is much easier to use the acoustic membrane as it can be stapled to the joists before affixing the resilient bars.
For customers looking to insulate noisy pipes please see our acoustic pipe wrap.

For those wishing to add membrane we offer two further calculators which will incorporate either the Tecsound or the acoustic membrane

How it works.

The resilient bar, or soundbreaker bar works by decoupling the new suspended ceiling from the joists. The new ceiling is in effect floating off the joists via lightweight corrugated steel bars. The sound is absorbed as it travels through the corrugated flange of the resilient bar. ( For a significantly higher performance see our Genie Clip solution)

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.

The removal of an old ceiling sounds a little daunting 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 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

Important note on recessed lights

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 can be purchased from our on-line store. Spotlight hoods

Soundproofing ceiling solution Ceiling Height loss Acoustic Performance Impact improvement Airborne sound
(Improvement db)
Impact Sound*
(Improvement db Average)
~66mm Good Airborne up to 6 db better than resilient bars on impact This solution provides best impact and airborne performance of suspended ceilings 19db+
Excellent improvement
85-91mm or 3 inches (ceiling retained) Good Airborne up to 4 db better than resilient bars on impact Hangers are preferred over resilient bars where impact sound is the bigger issue Good 18db+ improvement 16db
29-35mm or 1 inch (Ceiling removed) Medium Airborne/ medium Impact Good where carpeted above. Good 14db+ improvement 13db
~205mm or 7-9 inches (ceiling retained) Excellent Airborne excellent impact If structural Vibration occurring this should ceiling should be seriously considered. 23db+
Excellent improvement
Impact sound now only transmitted through walls
The action of the SBx board materially improves the performance of all solutions with particular emphasis on airborne sound. Improving it by around 8db over and above the stated performance.  


* Important note.

Sound Stop refers to Db improvement when it compares any of its 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 and products will boast much higher numbers but be aware these are often referring to a complete system which include the original surface. 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 in the market today.
