How to Soundproof Your Walls

Acoustic Ceiling Soundproofing Systems


Even in new build houses and flats, that are built using the correct materials and methods, loud noise produced by music and shouting etc will often still be heard and can be particularly worse in the evening when normal daytime background noises have stopped and the ambient background noise is therefore much less.

These solutions are designed to reduce airborne noise and/or impact noise through ceilings subject to any flanking noise issues that may be present. Flanking noise is where sound by-passes the treated ceiling and travels perhaps down the adjoining walls.

If you are suffering from noise problems travelling through a wall we offer three basic solutions. Click on the images to see more detail as well as enhancement options:-

acoustic ceiling soundproofing systems CAD20 ACOUSTIC CEILING PANEL SYSTEM
A 20mm thick, acoustic density, recycled rubber panel is glue fixed to an existing rendered brick wall.
2 layers of acoustic plasterboard are then glued ontop of the acoustic panel.
The perimeter isolation is acoustically sealed.
Improvements in the order of 8-10dB can be expected.
acoustic ceiling soundproofing systems RESILIENT BAR CEILING ISOLATION SYSTEMS
Timber furring battens are fixed to the wall to create a void for acoustic mineral wool insulation.
Flexible acoustic resilient bars are fixed onto the battens.
2 layers of acoustic plasterboard is fixed to the resilient bars.
The perimeter isolation is acoustically sealed.
Improvements in the order of 10-12dB can be expected.
acoustic ceiling soundproofing systems INDEPENDENT CEILING ACOUSTIC SYSTEMS
An independent metal or timber frame is built in-front of the existing wall.
2 layers of 12.5mm acoustic plasterboard are then fixed onto the independent frame.
The perimeter isolation is acoustically sealed.
Improvements in the order of 13-16dB can be expected.

Even in new build houses and flats, that are built using the correct materials and methods, loud noise produced by music and shouting etc will always be heard and can be particularly worse in the evening when normal daytime background noises have stopped and the ambient background noise is therefor much less. The other problem with noise from upstairs is that it's often impact (footfall noise) as well as airborne noise (TV etc.).

If you are suffering from noise problems travelling through from your ceiling above it would be wise to firstly try and do something to the upstairs floor before undertaking the installation of a false ceiling as this will help remove the impact problems at source rather than once the noise has got into the structure.

To gain the maximum reduction in noise nuisance from above, a separate ceiling installed on new joists beneath and not directly connected to, the existing ceiling and supported by isolated wall mounted joist hangers will give the best results.

The problem is that this method can normally only be installed in a new build situation or when a property has very high ceilings with no ornate cornices etc.

The only really effective option for ceiling soundproofing is to make use of soundproofing resilient bars. It is ESSENTIAL that the new ceiling is NOT physically attached to the existing structure. Simply screwing another sheet of plasterboard onto the existing ceiling simply won't do.

Ideally, remove the existing plasterboard (or add battens to the existing ceiling) and add Acoustic Mineral Wool or for much better performance use our High Performance Acoustic Quilt in the cavity space before fixing resilient bars to the joists (or battens). Two additional layers of 12.5mm plasterboard (or thicker) should be attached to the resilient bars. The second layer of sheets should overlap the seams in the first layer for improved performance. The edges of the plasterboard must NOT touch the existing walls. This small gap should be filled with non-hardening flexible mastic.

Additional performance can be obtained by fixing 1 or two layers of acoustic membrane inbetween the two sheets of plasterboard. This material damps the plasterboard. Small squares of our neoprene can also be used behind the resilient bars where they are attached to the joists for improved isolation.
