The Ultimate Guide to Plasterboard Soundproofing
Plasterboard soundproofing is a modern solution to an age-old problemâunwanted noise.
Whether it’s noisy neighbours, traffic, or just the airborne noise from electronics, sound can quickly become a nuisance.
In this blog, we will explore different ways to control noise levels using plasterboard, including the use of soundproof plasterboard and other soundproofing solutions.
Standard Plasterboard vs Soundproof plasterboard
Standard plasterboard, while widely accessible, possesses limited capabilities in noise reduction. Nevertheless, by increasing its thickness and employing the appropriate installation techniques, it can be adapted to provide certain acoustical advantages.
Acoustic plasterboards, on the other hand, are specifically designed to offer enhanced acoustic properties. Acoustic plasterboard is distinguished by a higher density core compared to standard plasterboard and is identifiable by its blue coloration.
This characteristic hue results from specific properties introduced into the gypsum during manufacturing and the colour of the paper strip employed to distinguish it from other varieties of plasterboard.
For example, moisture resistant plasterboard is typically green, while fire rated plasterboard exhibits a pink tint. These colour-coded distinctions facilitate the selection of the appropriate type of plasterboard based on the required properties and applications in construction.
We sell acoustic plasterboard in various thicknesses and a tapered edge variant from reputable brands such British Gypsum, Knauf, and Siniat. The most popular product is the Knauf Soundshield Plus, which comes in 12.5mm and 15mm thicknesses.
Why Soundproof?
Sound insulation is key in creating a peaceful environment.
Noise pollution affects not only our comfort but also our health and productivity.
Implementing effective soundproofing solutions can reduce noise pollution significantly.
Understanding Sound Energy
Sound energy travels in waves and can penetrate most materials.
The installation of acoustic plasterboard helps absorb sound energy, preventing sound transfer from one room to another.
Installing Acoustic Plasterboard
- Identify the Wall or Ceiling: Determine the type of wall (stud walls, party walls) or ceiling that needs soundproofing.
- Choose the Plasterboard: Pick the type of soundboard plasterboard that best suits your sound reduction needs.
- Prepare the Surface: Make sure the wall lining is suitable for plasterboard installation.
- Install the Plasterboard: Follow the manufacturer’s instructions, often involving the use of two layers for adequate soundproofing.
- Finish the Installation: Apply sealants and finishing touches to complete the installation.

Additional Soundproofing Solutions
Mass Loaded Vinyl
Mass loaded vinyl provides high density and can be used with plasterboard to reduce noise levels even further.
Mineral Wool
Mineral wool offers excellent thermal resistance and acoustic properties, working well with plasterboard to reduce both airborne sounds and impact noise.
Acoustic Insulation
Acoustic insulation is the process of using dense materials to limit the transmission of sound.
When sound waves come in contact with various substances, they generate vibrations. By forcing the sound wave to traverse through a material with more mass, the number of vibrations reaching the other side of that material diminishes, resulting in reduced noise transmission.
Materials that are dense in nature, such as fibreglass or mineral wool (which are available in rolls or slabs), have the ability to capture sound waves, stopping them from penetrating to the opposite side.
By installing these substances in walls, ceilings, and floors, they act to soak up sound and minimise the transfer of noise.

Conclusion
Whether you’re dealing with noisy neighbours, looking to increase thermal resistance, or seeking a higher standard in preventing sound transfer, plasterboard soundproofing provides a versatile and effective way to improve the quality of life in any living or working space.
