Ceiling Solution 1
Resilient Bars
If you wish to buy this solution online we can calculate the materials you need.
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 from your original ceiling height.
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.
 
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.
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.
