For some people, getting soundproofing sheetrock may be out of their financial capacity.

Another alternative is to use several layers of regular drywall.

With this method, you can apply Green Glue between double layers of sheetrock to prevent noise from traveling to the next room.

Installing more than one layer of standard sheetrock can provide adequate sound insulation; however, this method comes with numerous issues that can do more harm than good, like:

  • Fiberglass
  • Viscoelastic polymer
  • Rubber compound
  • Mass loaded vinyl (MLV)

Soundproof Drywall Buying Guide: Factors to Consider

Illustration on soundproofing drywall

Soundproof drywall can do wonders for reducing sound transmission, but it may not be a solution for everyone.

Before deciding whether to get soundproof or standard drywall, consider the following:

1. Acoustic Performance

Determine WHY you actually need to soundproof your property.

Perhaps you want a soundproof room where you can practice making music without disturbing anyone.

Maybe you want to block out street noise or your neighbors’ rowdy conversations.

Whatever the case, knowing what noise control you want to achieve will help you determine what soundproofing solution will work best for you.

Different soundproof drywall products have different properties that block various decibels and frequencies of noise.

Compare reviews on different soundproofing drywall panels to assess their acoustic performance.

You might not even need drywall panels, but instead need standard acoustic foam soundproof panels, which can be more affordable.

2. Value for Money

Soundproof drywall is an INVESTMENT.

Due to the increased noise control, it can come at a higher price point than your standard drywall.

The soundproof drywall cost can be up to $40 per sheet compared to standard drywall, which costs $10 on average.

If you’re on a budget but still want noise-reducing drywall features, you can choose to limit soundproofing in rooms where noise is a concern.

You don’t have to soundproof your entire house. Reserve soundproof sheetrock for your home office or bedroom.

3. Installation Process

The installation process of your construction or renovation project is a crucial consideration if you’re thinking of including soundproof drywall.

Most soundproof drywall manufacturers offer easy installation options, but some products require professional installation.

You’ll need to account for labor costs, lead time, and the entirety of the installation timeline.

Adding additional layers of standard drywall actually takes MORE time than installing soundproofing drywall.

A single-layer installation of soundproof drywall also cuts back on labor costs compared to installing multiple layers of regular drywall.

We recommend going for soundproof drywall panels whenever possible. They’re cost-effective and don’t require a complex installation process.

4. Durability

Another factor you need to look into is how sturdy your drywall will be.

A sound-dampening drywall will cost you more than a traditional one, so you’d want it to last for several years!

Using multiple drywall layers can give your wall enough added thickness to withstand damage.

5. Location

WHERE you want to apply soundproofing in your house can also help you choose which drywall to use.

If you’re going to put soundproofing materials on the same level as other rooms, you’d want thick sheetrock for better soundproofing.

Alternatively, if you plan to install drywall in the basement, the floor space provides another barrier to sound.

Frequently Asked Questions

Here are some related questions about soundproofing drywall that can help you:

How Does Drywall Reduce Sound Transfer?

Soundproofing uses barriers like drywall that absorb and dampen sound waves to reduce sound transfer from one room to another.

It’s intended to specifically BLOCK impact or airborne sound. There are many ways to use drywall to soundproof a space:

Absorption

Sound-absorbing materials are applied between the inner layer of drywall to
deaden sound vibrations.

There are several materials that can be used to absorb sound, such as:

Fiberglass
Viscoelastic polymer
Rubber compound
Mass loaded vinyl (MLV)

Dampening

Drywall can also be used as dampening panels that cancel out sound waves.

Using a dampening compound between two layers of drywall can help reduce noise.

Applying Green Glue compound provides an additional layer that can increase your STC score by at least ten points.

Green Glue is a viscoelastic compound that disperses sound waves when applied in between layers of plaster.

Decoupling

Sound waves require a medium to pass through in order to be heard.

Decoupling aims to disrupt this process by separating wall attachments from the studs to interrupt the pathway of sound vibration.

You can build a staggered stud wall that effectively decouples the connections that allow sound energy to pass through.

Mass

Adding mass to your drywall is another way to block sound.

For sound to transmit, it needs to make a medium vibrate. Providing greater mass density using a dense layer of drywall means greater resistance against sound vibration.

A double layer of 5/8″ drywall is one of the most effective alternatives for soundproofing.

What’s the Difference Between Soundproofing and Sound Absorption?

Soundproofing primarily intends to block sound from leaving a space.

Sound absorption uses materials that soak up extra sound energy that causes bad acoustics. It doesn’t necessarily stop noise from traveling, but it can improve sound quality.

Both processes often work TOGETHER to achieve the desired level of sound control and reverberation reduction.

How Good Is a Drywall for Soundproofing?

Soundproofing drywall does NOT guarantee complete silence, but it is the most effective solution to noise problems.

Soundproof drywall consists of materials like calcium sulfate dihydrate (gypsum), viscoelastic, and ceramics that make it difficult to transmit sound waves.

If installed correctly, it can make a HUGE impact on your living or workspace.

Conclusion

There are many ways to achieve good soundproofing, such as placing fiberglass insulation, installing sound-absorbing materials on an entire wall, or strategically utilizing air gaps in between walls.

Soundproofing drywall is arguably the most cost-effective method to block unwanted noises.

In this list, we covered the best products on the market that can give your space better acoustics.BUT REMEMBER, the best drywall for soundproofing will depend on your preferences, financial capacity, and the needs of your project. Good luck!
