Does SoundProof drywall really work? Everything you need to know

SoundProof drywall is a modern alternative to the plaster or brick block that was used 50 years ago and is gaining popularity today because it is easy to use on construction sites at minimal cost.

Such drywalls are using to separate your house from neighbors or rooms in the house at a minimal cost and to reduce construction costs such as transportations, setting up plaster or brick blocks.

When it comes to covering existing walls or new walls or ceilings with new alternatives, this DIY friendly soundproof drywall is becoming increasingly popular and hard to beat.

The main cause of problems with noisy neighbors is single-layer or low quality drywall, and people have started to install standard drywall for partitions between two houses.

Almost every new home owner uses drywall because it is easy to install and place anytime, anywhere. However, are you absolutely sure that installing soundproof drywall will help you deal with the noise from the house next door?

I suppose so if this can be done properly but soundproof drywall, is not the only factors in breaking this noise down. There are several others. So don't miss how to soundproofing a room.

But our request is still alive. Does soundproof drywall really works? To get an idea, it is better to understand what drywall is.

What is SoundProof drywall? in Detailed

Well, SoundProof drywall and drywalls are the same. The only difference is the thickness and quality of the material used for noise blocking. So let's find out what drywall is.

Drywall is made by the same materials as the plaster that was previously used to build houses, and the material is Gypsum.

Drywall is also known as gypsum panel, gypsum board, or plasterboard, which is creating with calcium sulfate dihydrate (gypsum) or without additives.

This plaster is mixed with fiber, plasticizers and foaming agents, as well as various additives to reduce water absorption.

To make plasterboard, crystal of Gypsum are crushed into fine particles then mixed with water to make a paste and then mixed with the above ingredients.

During manufacture, the liquid gypsum slurry is poured into bags made of thick recycled paper to give it a specific flat shape.

So, a second finish coat is created by pouring another layer of liquid pulp on top of the previous one into another light density pocket paper.

Now the third layer is created by pouring high density onto the second layer, creating a full sandwich structure where the drywall is finished with two layers of thick layers and one medium light layer.

The thickness of the plates depends on the needs. Sometimes just one thick layer is enough, with other layers maybe more than 3.

Therefore, soundproof plasterboard is made of an inner layer of insulating materials such as gypsum or viscoelastic, and ceramics, so that it is more durable and increases the ability to block the passage of sound waves.

After the sandwich layer is ready, the next process is to dry this drywall and make it as hard as a strong board.

Easy to transport and can be used on site for quick installation and getting the job done at a lower cost.

However, note that sound waves cannot easily propagate through thicker walls, but rather easily through thinner walls.

Of course, using brick blocks can help you minimize sound waves very effectively, but what if you are using drywall? Is Soundproof Drywall So Effective?

Does soundproof drywall really works?

Soundproof drywall can prevent noise from entering your home and, depending on the installation, act as a sound blocker.

Few people use multiple layers to add wall to wall, which is technically effective according to the laws of physics. The denser the area, the more noise you can block.

Well, you know that what is soundproofing? it's the ability of any material to block sound, preventing sound waves from passing through.

There are two things that need to be considered, namely soundproofing vs Sound absorbing. So study first in our detailed guide for explanation.

The soundproofing of each material is classified into the sound transmission class (STC), with class 40 being standard and suitable for all soundproofing materials.

However; the STC for soundproofing drywalls sits between 50 and 55, which is more than the standard STC for drywall and good enough to handle noise blocking.

It does it's job very correct and in mostly cases you can't hear the sound on the other side of the wall.

Remember that sound waves travel in the form of particle motion, similar to vibration or mechanical energy. If you are using a thin layer of drywall that vibrates a lot, soundproof drywall will not do this.

Soundproof drywall is build of gypsum materials, with a plaster of layers interspersed with a layer of glue or other polymer material.

That makes it difficult and there is less vibration and less chance of noise waves passing through. Soundproof drywall is thicker, than standard drywall and about 5/8 inch thick.

Hence, soundproof drywall works well. The only fact is how it is installed.

Install the SoundProof drywall?

Soundproof drywalls are available in standard 4 x 8 feet and can be up to 8.9.16 feet larger depending on your needs.

It can be a quarter of an inch to 5/8 inch thick so you can choose effective drywall, but keep in mind that regular, soundproof drywalls is about 5/8 inch thick.

Of course, buying soundproof drywall can be expensive when compared to standard drywall, but it's good for peace and privacy.

The choice of drywall should be made as needed, as few wall is moisture-resistant compared to small drywall which is fire resistant and slightly flexible. Like drywall with moisture, they have fiberglass or polymer to resist water damage.

Installing soundproof drywall can be done by hanging it up and finishing it later.

The hook requires muscle strength to hang around corners or joints by drilling into the ceiling or side corners. You can use a rubber band to prevent drilling on the other side of the wall.

Resilient, is a thin metal material which, if present, can be drilled into an existing wall / ceiling. In addition, you can get drywall yourself with screw soundproof drywall.

After the suspension and fastening have finished this time, you will need to glue the joints or corners where these whole sheets of drywall are joined. This is a finishing ability.

You can glue these joints or gaps with masking tape, which is an adhesive made from a thin layer of adhesive mixture. Another option is to use mesh paper, which is adhesive and sticks to the front of the paper.

All tape should be covered with at least three coats of mud or glue to make sure the joints don't stay open and that everything looks well-made and smooth.

After all the layers have dried, all the mud is sanded down to remove everything and prepare the walls for paint purposes.

Here hanging and clamping drywall, is a muscle power process, but finishing it is something of a DIY skills, or I would say a high DIY skill.

how to soundproof existing drywall?

Of course, if you already have drywall or want to make the walls soundproof, you are not going to replace the existing one.

Here the finest solution is to buying new drywall and covers the existing walls with a new layers of drywall, which in turn adds mass to the existing walls and makes your wall surface denser.

You can find more information on how to soundproofing walls in our detailed complete guide. Here are some tips, such as buying a thin layer of drywall that costs less.

Attach it to the existing wall, but create a separate area between the existing wall and the new drywall that you adjusted. This picks up sound waves and reduces vibrations from one wall to another.

This zone of separation, where noise is trapped, can produce resonance. So make sure to fix it by using green glue between the two walls. The insulation is now soundproof.

Hope you like how the existing walls soundproof, and don't forget to study in detail.

My Opinion on drywall is soundproof

Obviously using drywall for construction purposes to minimize the cost of materials like drywall or anything else.

Well, I advise you not to bother with privacy and make sure you only install soundproof drywall that is thicker and very effective at blocking noise.

If not, find a way to minimize this noise while sleeping with the help of using earplugs which are not healthy for you. Why are you finding answers for alternative of earplugs, or soundproof windows or doors here?

So make sure you have soundproof drywall or convert an existing wall into soundproof drywall. Check out the STC ratings for new drywall buyers that give you confidence in noise control capacity.
