What is acoustic plasterboard?
Acoustic plasterboard, commonly known as soundproof plasterboard or sound resistant plasterboard, is an enhanced version of standard plasterboard designed to offer a strong level of sound insulation.
The material has a high density, and this largely contributes to its noise reduction property. The higher the density of the blue plasterboard, the greater its acoustic property. Besides, plasterboard can be combined with other soundproof materials such as fiberglass or mineral wool in order to enhance its ability to absorb and block noise.
Applications
Soundproof plasterboard is utilised in many applications such as in ceilings, floors, and walls. It is the best material to choose to reduce noise traveling between floors or rooms and block noise from noisy neighbors. The best thing is that the installation is not complicated, and therefore you can DIY.
How effective is soundproof plasterboard?
On average, acoustic plasterboard minimise sound vibrations by 42 dB. Even if you install a single layer of dB board on the stud wall, you ought to still achieve 42 dB noise reduction.
Humans can perceive a noise reduction as low as 10 dB. So, a noise reduction difference of 42 dB would almost represent a 90% reduction in your current noise levels coming via the walls.
However, if you have not soundproofed the rest of the rooms or some cavities where sound can leak, soundproofing your walls won’t bring any difference. But as long as you consider that, installing blue plasterboard is a worthy investment.
Benefits
Regardless of where you install your acoustic plasterboard; on the walls, ceiling, or floor, you enjoy the following benefits.
Note: For optimal soundproof performance, make sure that most of the surfaces of your home are insulated.
- Enhances acoustics, and therefore you can communicate without interference and understand the message better.

Where is sound plasterboard used?
Sound plasterboard is used in enclosed spaces where noise levels need to be kept low. These include areas that require quiet and privacy, as well as multi-storey buildings and shared walls through which sound tends to travel.
It is installed on walls and ceilings and commonly found in bedrooms, home offices, office blocks, schools, hospitals, apartments, hotels, and recording studios.
How to fit acoustic plasterboard?
Step 1: Prepare the frame – Attach the studs to the structure, ensuring they are positioned squarely.
Step 2: Add insulation – Optional, but recommended when you need to insulate the area. Fit insulation between each stud before boarding to enhance acoustic performance.
Step 3: Install the boards – Mount the plasterboard into position, with the coloured side facing out and the edges tightly closed together to minimise any gaps.
Step 4: Fasten boards – Secure each board using the correct plasterboard screw type for your frame. Maintain uniform spacing to keep the surface consistently secure and neat.
Step 5: Stagger joints (for double layers) – This step applies only when you are fitting two layers. Offset the joints so they do not align. This will help block potential sound transfer.
Step 6: Seal all gaps – Fill the edges and joints with acoustic sealant.
Step 7: Tidy up – Apply joint tape and compound, then sand smooth for a professional, uniform finish.
