Soundproofing Your Ceiling
The main concern with ceilings is loud impact noise from above.
Acoustic control methods are very similar to those for walls. Barrierboard is the perfect solution and can be either installed as the primary ceiling material or as a retrofit onto the existing ceiling either directly fitted or mounted using furring channels and acoustic insulation between the primary and secondary ceiling.

In offices, if walls are adequately insulated but the ceiling is not, cross-talk can be an issue. Cross-talk is the noise that travels over the wall through the ceiling, which is the weakest link.
Soundblock NuWave barrier material can be used to address this common problem. It is also suitable for ceiling voids in offices that have suspended ceilings to bridge the gap between the true ceiling and the top of the partition wall.

How to Soundproof Your Gyrock Or Concrete Ceilings
To successfully soundproof a ceiling you need to add significant density combined with absorption and ensure all gaps are sealed for an air tight finish.
Our Barrierboard composite gyprock sheet has been designed to maximise sound reduction between rooms sharing a common ceiling/floor. Barrierboard together with our acoustic insulation can improve a room’s acoustics by as much as 75%.
Where impact noise is the problem, the main method of control is to install a secondary ceiling by fastening isolation mounts to the existing ceiling, attaching metal furring channels to the isolation mount and placing Polymax Absorb insulation between the channels. Barrierboard is then fixed to the furring channels. This will drop your ceiling height by 64mm but it will structurally isolate your old ceiling from your new ceiling.
Ceiling depth loss would be either 32mm when direct fixing Barrierboard or from *64mm when using isolation mounts (*depending on isolation mount used and levelness of ceiling). This can be assessed by our installation team or your own installer as required.
How to Soundproof Your Suspended Grid Tile Ceilings
Before you treat the partition wall it is best to stop the flanking noise travelling over the top via the suspended ceiling tiles. By fixing NuWave Barrier to the true ceiling and suspending it down to overlap the partition wall within the ceiling void, you can arrest the transmission of sounds from one office area to another. This will also improve the wall performance as it will be under achieving at present.
If the noise isn't excessive, another option to bridge the gap are Ceiling Baffles. The Polymax Easy Baffle will absorb the sounds transmitting across the partition wall.
