The Pros and Cons of Acoustic Plasterboard

What is the difference between a standard plasterboard and an Acoustic plasterboard?

The main difference between a normal plasterboard and an acoustic plasterboard lies in thier density. Sound deadening plasterboards have acoustic properties due to thier higher density core

While both types of plasterboard are made from gypsum, sound resistant plasterboard contains additional materials, such as mineral wool or glass fibre, that improve its ability to absorb sound waves. 

This means that sound block plasterboard is better at reducing noise levels and preventing sound from passing through walls and ceilings. They can help reduce sound by around 30 to 50 decibels. However, this added density can also make acoustic plasterboard heavier and more difficult to install than standard plasterboard.

How to Install Acoustic Plasterboard?

Installing acoustic plasterboard is a process that requires careful planning and attention to detail. You can install acoustic plasterboard directly onto the walls to achieve some reliable wall soundproofing. Here are some general steps that may be involved in the installation process:

1. Prepare the surface: Make sure the surface to be covered is clean, dry, and free of any debris. If there are any gaps or cracks, fill them with an appropriate plasterboard filler.
2. Measure and cut the plasterboard: Measure the dimensions of the area to be covered and use a saw or knife to cut the plasterboard to the appropriate size.
3. Install the plasterboard: Apply a layer of drywall adhesive to the back of the plasterboard and press it firmly against the surface. Use screws or nails to attach the plasterboard to the wall or ceiling.
4. Seal the edges: Once the acoustic drywall is in place, use a sealant to cover the edges and any gaps between the plasterboard and the surrounding surfaces.
5. Finish the surface: Depending on the desired finish, you may need to apply a layer of joint compound and sand it down to create a smooth surface.

It's important to note that the installation process for sound deadening plasterboard may vary depending on the specific product and the requirements of the room or building. For best results, it's recommended to follow the manufacturer's instructions and consult with a professional installer if necessary.

Is Soundproof Plasterboard worth it?

Whether or not sound rated plasterboard is worth, depends on the specific needs and circumstances of the building or room in question. 

Sound reducing plasterboards can be a good investment if the room requires a considerable level of soundproofing. Thanks to its high density, soundproof drywall can shield you from up to 50 decibels of sound which can be the difference between comfort and discomfort.

It can help to reduce noise levels and improve the overall acoustic performance of the space. Moreover, since they are thinner compared to mineral wool batts, they are ideal for soundproofing walls without taking up much of the floor space. Additionally, acoustic plasterboard can provide thermal insulation and be used to create decorative finishes.

However, sound block plasterboards may not be necessary or cost-effective for every situation. For example, if the room already has good soundproofing, or if the noise levels are not a major concern, then the benefits of acoustic plasterboard may not outweigh the additional cost and installation time. It's important to consider the specific needs and budget of the project before deciding whether or not to use soundboard plasterboard

Where to use Acoustic plasterboard?

Acoustic plasterboard can be an excellent option for soundproofing homes, especially in areas with high traffic. It reduces noise pollution in rooms that are noisy. Sound resistant plasterboard can be used to make walls thicker and can be easily painted. While it’s not as dense as mass-loaded vinyl, it’s still a very good choice for soundproofing.

These sound resistant plasters can be used to enhance soundproofing by adding mass to stud walls. This will keep sound waves from penetrating the walls and making them more difficult to vibrate. Therefore, by restricting sound transfer through the wall they provide effective soundproofing and give you a quiet, more relaxing home.

Cost of Installing Acoustic Plasterboard

The cost of installing acoustic plasterboard in pounds can vary depending on various factors, such as the size of the room, the thickness and density of the plasterboard, and the complexity of the installation process. In the UK, the cost of acoustic plasterboard can range from £15 to £30 per sheet or more.

The cost of installation will also depend on the method used and the installer's hourly rate. Installing acoustic plasterboard can be more time-consuming and labor-intensive than traditional plasterboard, and may require specialised tools and techniques. For example, the plasterboard may need to be screwed or glued in place, and the edges may need to be sealed with a special tape or filler to prevent sound leakage.

The cost of installing acoustic plasterboard wall will depend on the specific requirements and challenges of the project. It's recommended to get a quote from a professional installer to get a more accurate estimate of the cost.

Pros and cons of acoustic plasterboard

The Pros of Acoustic plasterboard boil down to the following:

1. Improved sound insulation: Acoustic plasterboard is specifically designed to absorb sound waves and reduce noise levels, making it an effective solution for soundproofing walls and ceilings. It is also a good choice for party walls, which are often a source of noise.

2. Thermal insulation: Acoustic plasterboard can provide additional thermal insulation, helping to keep the room warm and reducing energy costs.

3. Durable: Acoustic plasterboard is made with high-quality materials that are durable and long-lasting, reducing the need for frequent repairs or replacements.

4. Versatile: The pros of acoustic plasterboard are that it is suitable for use throughout the house. Acoustic plasterboard can be used in a variety of settings, including homes, offices, recording studios, and cinemas, making it a versatile solution for a range of soundproofing needs. Acoustic plasterboard is also an excellent choice for garages because it can help keep noise out and insulate the space better.

5. Saves Space: Sound resistant plasterboards are thinner compared to other soundproofing solutions like mineral wool batts. It saves the much-coveted floor space and is ideal to achieve sound reduction in places with space constraints.

Cons of Sound Deading Plasterboards:

1. Availability: Depending on the specific brand, product and location, sound reducing plasterboard may not be as readily available as traditional plasterboard, which can increase the cost and lead time for installation.

2. Installation complexity: As with any construction material, installing acoustic plasterboard can be complex and require specialized skills and tools. Additionally, they weigh more which can further increase the cost of installation and may require professional help.

3. Cost: In the UK, the cost of acoustic plasterboard can range from £15 to £30 per sheet or more, which is dearer compared to the standard plasterboards.

4. Impact Noise: Acoustic plasterboard works by absorbing airborne noise and stopping the sound energy from travelling through the wall. However, it is not very effective in blocking impact noise. Because it sits directly on the existing wall, some vibrations may still travel through it. 

In Conclusion:

In conclusion, soundproof plasterboard can be an effective solution for soundproofing walls and ceilings in a variety of settings. It is designed to absorb sound waves and reduce noise levels, providing improved acoustic performance and additional thermal insulation.

However, there are also some drawbacks to consider, such as the higher cost, installation complexity, weight, and limited soundproofing. Ultimately, the decision to use sound-resistant plasterboard will depend on the specific needs and circumstances of the project, and it's important to weigh the pros and cons carefully before making a decision.
