Does SoundProof Drywall Really Work? All You must know

SoundProof Drywall is a modern alternative of the plaster or brick block which were used before 50 years and becomes more popular these days as easy to use at the construction site for the minimum cost.

Such drywalls are used to partition your house from the neighbor or the rooms within the house for minimum cost and reduce the construction cost such as transportation, plaster or setting up brick blocks.

When it comes to cover the existing wall or new wall or ceiling with any new alternative than this DIY friendly soundproof drywall becomes more popular and hard to beat.

The main reason to get trouble from a noisy neighbor is a single layer or low-quality drywall and people started fitting standard drywall for partition purpose in between two houses.

Almost every new owner of the house is using Drywall as it is is easy to fit and quick to set anywhere anytime but do you really think setting up a soundproof drywall help you to overcome noise coming from next door?

I think yes if this can be done in the right way, but soundproof drywall is not the only factor to overcome that noise there are few others so do not miss on how to soundproof a room.

But still, query for us is live on does soundproof drywall really work? To get an idea, it is better to understand what is this drywall?Does SoundProof drywall really work?

What is SoundProof Drywall?

Well Drywall and SoundProof drywall both are the same only difference is with their thickness and quality of materials used to block the noise so let learn what is Drywall?

Drywall is made of the same material as plaster the one which was used previously for construction purpose of the house and that material is Gypsum.

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

This plaster is mixed with fibers, plasticizers and foaming agents and a various additive which help it to reduce the water absorption.

To create drywall the crystal of Gypsum is grind into fine particles and then mixed with water to create its paste and later mix with above-suggested ingredients.

During manufacturing, the slurry of the liquid gypsum poured into the pocket of recycled thick paper to give this a defined flat shape.

In such a way second top layer created by pouring another layer of liquid slurry on top of the earlier one in another pocket of paper with light density.

Now the third layer created with high density pouring on top of the second one and create a full sandwich structure where plasterboard ready with two facing dense layer and middle light layer.Gypsum Drywall panel

The thickness of the board will depend on the requirement, sometimes only a single thick layer is good enough however on others maybe the layers could be more than 3.

Hence the soundproof drywall is made with an inner layer of insulating materials like gypsum, viscoelastic and ceramics which makes them more resilient and increase the ability to block the noise waves to pass through.

Once the sandwich layer is ready the next process is to dry that plasterboard and make this rigid like a strong board.

This is easy to transport and can be used at the construction site to fit quickly and finish the job with lower cost.

But Remember the soundwaves can not pass easily through the denser wall however, can easily through the thinner wall.

It is obvious that the use of brick blocks can help you to minimize the soundwaves quite effectively but what if you use drywall? Does soundproof drywall is that much effective?

Does Soundproof Drywall really work?

Soundproof drywall can block noise to come to your house, it can act as sound blocker depends on its installation.

Few people use multiple layers to increase the mass of the wall which is technically effective as per the laws of the physics. The denser area you have the more noise you can block through that.

Well, you know what is soundproofing, it is the ability of any material to block the sound which prevents the soundwaves to pass through it.

There are two things to be in mind soundproofing vs Sound-absorbing so make sure you learn them first in our detail pictorial well explanatory guide.

Soundproofing of any material is rated in Sound transmission class (STC) where the rating of 40 is standard and well fit for any soundproofing material.

However, the STC for soundproofing drywall is in between the 50-55 which is more than its standard drywall STC and good enough to deal with noise blocking.

It does its job very accurately and in most cases, you can not hear the voice on the other side of the wall.

Remember soundwaves moves in the form of movement of particles which is sort of vibration or mechanical energy and if you are using thin layer drywall which vibrates a lot but this is not the case with soundproof drywall.

Soundproof drywall is made of gypsum materials, where the layer of gypsum alternated with other glue or polymer materials layer.

Which makes it rigid and there will be fewer vibrations and fewer chances for noise waves to pass through, Soundproof drywall is thicker than standard drywall and it is around 5/8 inch thick.

Hence yes soundproof drywall work well the only matter of fact is how you install this. 

Installation of SoundProof Drywall?

Soundproof drywalls are come into the standard size of 4 feet by 8 feet and can be larger in size up to 8,9,16 feet depends on requirement.

It can be thicker from the quarter of the inch to the 5/8 inch so you can choose the effective drywall but remember the usual soundproof drywalls are around 5/8 inch in thickness.

It is obvious that it can be expensive to purchase the soundproof drywall as compared to standard drywall but it is worth having for peace and privacy.

Selection of the drywall should be done according to the need as few walls are moisture-resistant than few are fire-resistant and few are flexible drywall. As in the case of moisture drywall, they have fiberglass or polymer facing to resist the water damage.

Installation of the soundproof drywall can be done by hanging and later finishing.

SoundProof Drywall

Hanging takes muscle power to hang around the corner and joints accordingly by drilling to the ceiling or side corners. You can take help of resilient to prevent drill on the other side of the wall.

Resilient is a thin metallic material which can be a drill against the existing wall/ceiling in case you have any and on top of that you can get screw your own soundproof drywall.

Once the hanging and fixing get completed this time is to tape the joints or corners where all this drywall panel got connected which is the skill of finishing.

This joints or gaps you can tape with paper tape which is glue kind of thin layer of joint compound and the other way is using the mesh paper which is adhesive and gets stick to the face of the paper.

All this tape must be covered with at least three coats of mud or glue which ensure no joint left open and everything looks well finished and smooth.

Once all the coat is dried then all mud will be sanded with sandpaper to remove everything and get ready wall for the color purpose.

Here hanging and clamping drywall is a bit muscle power process however the finishing is sort of DIY skills or I should say high DIY skill.

How to Make Existing Drywall to SoundProof?

Well, it is obvious that if you are already having drywall or willing to make this wall to soundproof then you are not going to replace the existing one.

Here the best solution is to buy new drywall and cover the existing wall with a new layer of drywall this in result increase the mass of the existing wall and make your wall surface denser.

To learn more on how to soundproof a wall make sure to learn in our detailed exclusive guide. Here are a few tips such as buy a thin layer of drywall which will be cheaper in cost.

Fix it with the existing wall but create a decouple area in between the existing wall and new drywall you are setting, which will trap the noise waves and reduce the vibration from one wall to other.

This decouples area, where noise trapped, can create a resonate so make sure to overcome that by using green glue in between both walls and now you are done with soundproofing your existing wall.

I hope you like this way to make your existing wall soundproof and not forget to learn in detail.

My view on Soundproof Drywall

It is obvious to use drywall for the purpose of construction for minimizing the cost of materials like plaster bricks or any other things.

Well but I advise not to deal with the privacy and make sure to have installed the soundproof drywall only which is thicker in size and quite effective in blocking the noise.

Otherwise, you will be searching the way on minimizing this noise while sleeping using earplugs which are not fit for health, why here is an answer for alternatives of earplugs or start soundproofing window or door.

So make sure to have soundproof drywall or make your existing wall to soundproof drywall, check the STC score for each new buying drywall which gives you confidence on its noise blocking capacity.
