choosing the drywall for soundproofing


When it comes to soundproofing, not all drywall is created equal. Choosing the right type of drywall can make a big difference in how effective your soundproofing efforts are. Drywall is a crucial element in any construction project, whether it is a home or business. It is responsible for creating smooth and even walls, as well as providing insulation and soundproofing. With so many options available, choosing the right drywall can be overwhelming. In this blog post, we’ll discuss the different types of drywall and how they can help you create a more soundproof space. In addition, we will also take a look at the factors you should consider when choosing the right drywall for soundproofing. 

Things To Do When Choosing the Right Drywall for Soundproofing

Different Types of Drywall for Soundproofing

Sound Reduction Drywall 

The most common type of sound reduction drywall is made with a layer of gypsum sandwiched between two layers of paperboard. This type of drywall has been specially designed to reduce the amount of noise that travels through walls and ceilings. It’s available in both ½-inch and 5/8-inch thicknesses and comes in various lengths. The thicker the drywall, the better it will be at blocking out noise. However, it’s important to note that thicker drywall also weighs more, so it may not be suitable for certain applications where weight is an issue. 

Noise Barrier Drywall 

In some cases, you may need even greater soundproofing than what regular sound reduction drywall can provide. In these cases, you may want to consider using noise barrier drywall. This type of drywall contains two layers of gypsum board with a layer of resilient vinyl between them. This combination helps to block out even more noise than regular sound reduction drywall – up to 50% more! Noise barrier drywall is available in both ½-inch and 5/8-inch thicknesses and comes in various lengths as well. As with regular sound reduction drywall, thicker boards offer better soundproofing but come with a higher price tag and extra weight considerations. 

Impact Resistant Drywall 

If you’re looking for maximum protection from both noise and physical impact, then impact resistant drywall is the solution. Impact resistant drywall is also known as “shock resistant” drywall. It is made with either one or two layers of gypsum board laminated onto wood fiber panels or high-density polystyrene foam cores which help absorb impact energy and prevent it from traveling through walls and ceilings. Thus providing superior protection against both noise and physical damage caused by everyday wear and tear or accidental bumps or bangs around your home or business premises! Impact resistant drywalls are also available in both ½-inch and 5/8-inch thicknesses (depending on your needs) as well as various lengths – although these boards tend to be slightly heavier than their standard counterparts due to their additional protective layer(s). 

Factors to Consider When Choosing the Right Drywall for Soundproofing

Sound Transmission Class (STC)

The Sound Transmission Class (STC) is a rating system that measures how well a wall or partition can block sound. The higher the STC rating, the better the wall or partition is at blocking sound. When choosing drywall for soundproofing, look for options with a high STC rating.


Thickness is another important factor to consider when choosing drywall for soundproofing. Thicker drywall is typically better at blocking sound than thinner drywall. However, thicker drywall can be more expensive and take up more space. When making your decision, consider the cost and space constraints of your project.


Density refers to the weight of drywall per square foot. The higher the density, the better the drywall is at blocking sound. High-density drywall options are typically more expensive, but they provide better soundproofing than lower density options.

Type of Drywall

There are several types of drywall available, including standard drywall, soundproof drywall, and resilient channel drywall. Standard drywall is the most common type of drywall and is typically used in residential construction. Soundproof drywall is specifically designed for soundproofing and is a good option for businesses or homes where soundproofing is a priority. Resilient channel drywall is a type of soundproof drywall that is installed using metal channels to reduce sound transmission.


The installation of drywall is just as important as the type of drywall you choose. A poor installation can result in gaps and cracks that can undermine the soundproofing properties of your drywall. Make sure to hire a professional contractor who has an experience in installing drywall for soundproofing.


All three types of soundproofing materials have their benefits depending on the specific needs of your home or business premises. However, regardless of which material you choose, there are certain basic installation practices that should always be followed when installing any type of insulation material such as making sure all seams are sealed properly with caulk or tape as well as ensuring all joints are securely fastened together using screws rather than nails. With just a bit of careful planning and attention to detail, you can ensure that your space is optimally insulated against unwanted outside noises while still allowing ample amounts of natural light into your home without sacrificing any functionality! 

Choosing the right drywall for your home or business based on soundproofing needs requires careful consideration of several factors. Consider the STC rating, thickness, density, type of drywall, and installation method to ensure you select the right option for your project. By taking these factors into account, you can ensure that your walls provide the soundproofing you need and the peace and quiet you deserve.

Choosing the right type of insulation material based on its intended purpose is essential if you want to achieve maximum effectiveness when creating soundproofed spaces within your home or business premises. Luckily, there are plenty of different materials available today that cater specifically for this purpose! Hopefully this blog post has been able to shed some light on which type might be best suited for your particular situation. That way you can make an informed decision when selecting insulation materials for upcoming projects! Thanks for reading!
