best soundproof insulation guide -Due to increasing types of machinery and daily traffic, it becomes most popular in different countries to soundproof a house, car, private room or office spaces using the soundproof insulation, but what is the use of insulation in soundproofing?
Have you ever thought about what is the difference in between soundproofing and soundproof insulation and why every time people ask us to use soundproof insulation for soundproofing, bit confusing right?
Soundproofing of any space can be done through plenty of other products but out of them, the very most effective solution is soundproof insulation.
It is a core part of soundproofing as its ability to block the soundwaves which in result less noise transmission from one side to other and let me clarify you it is used for the purpose of soundproofing only not sound-absorbing.
Do you know the differences in between soundproofing vs sound absorbing? If not make sure to learn from our detailed guide.
I have an answer for all your queries on what is soundproof insulation and how it works and what are the best sound insulation available in the market and what parameters you should check prior to buying any sound insulation.

What Is SoundProof Insulation?
If we talk about the soundwaves, it travels faster in air space as compared to dense. Which means to block unnecessary sound or noise, we need a strong barrier which creates trouble for soundwaves to pass through it.
Probably you heard about the drywall which screwed against the verticle studs which left the cavity in between verticle studs and make them a weak barrier and compromise your privacy from the other side of the wall.
The insulation material is the best choice to fill the same gap. Usually, every single wall is filled with insulation material to cover that cavity and create a strong barrier for the sound coming from the other side of the wall.
They are made of loosely packer fiber, mineral wool or cotton, etc. Out of all three, the standard fiberglass insulation is cheaper as compared to mineral wool insulation but not that much effective for soundproofing.
Well, most of the walls are made in the factory and directly installed at the construction site for easy, quick and cheap construction cost but that does not provide you quality in terms of a sound barrier or privacy.
To avoid this, insulation is widely used to dampen the soundwaves while passing from one side to another side of the wall, it also helps to maintain the heat inside the room and save electrical energy.
Well, I imagine you got the idea behind the use of insulation let me help you classify what types of insulation available?
Types Of Insulation
Soundproof insulations are of different types and can be used for varieties of purposes and that is why it has been categorized into three parts.
I was searching on different websites to get an idea on category or types of insulations and here are few of them.
Batt Or Roll Insulation
Batt insulation is made of fiberglass or rock wool and probably the same as what you can imagine in your mind. These are available in varieties of thickness depends on your need but usually in flat pieces.
Batt installations are usually used to install in between the verticle wooden studs to fill the cavity behind the drywall, it could have a front-facing or maybe not.
Batt insulation is made of tightly fiberglass woven strands which come together to create a matrix, and because of multiple strands layer, it creates a strong barrier.
It is one of the best fiber proof insulation materials available in the market, which makes it an ideal choice for older homes.
Similarly, Roll insulation available in the rolls instead of flat pieces and are made of the same type of materials and both come under the conventional category of insulation.
It is another type of insulation which is excellent as compared to Batt or Roll insulation. Blown-in insulation is made of cellulose compound or loosely fiberglass materials, so it can not be installed using the homeware solutions and must be applied by the professionals.
In terms of insulation, it is similar to batt and roll type insulation but blown-in insulation is non-toxic and fireproof and less moisture seeping which in result zero chances of rodents finding into the insulation
Blow-in insulation is treated with boric acid and other substances which makes them flame-resistant and then it is packed in tightly packed bags.
This insulation is easy to mold which can fit or reach any area very easily as compared to batt or roll insulation.
This provides an R-Value (R-Value is a measure of insulation effectiveness) higher as compared to batt or roll insulation and one of the best-recommended solutions to fill the studs wall cavity.
This is favorite among those homeowners who prefer green products, as it is made of recycled materials like paper and wood products with the chemical involved through a synthetic process.
Spray –Foam Insulation
As the name suggests it is in liquid form which can be inserted into any cavity and one of the most popular insulation which is ideally done by the specially trained professionals.
It has the ability to expand 100 times then to its actual volume, which helps to create the airtight and fill all the gaps whatever possible in the cavity.
Due to strong airtight, it left very little space for air leakage and that cause it specially used to fill ceiling, walls, and floor cavities.
Out of the three, it is obvious that blown-in and spray-foam insulation are among the most popular and highly effective insulation solution and even expensive too.
If we talk about the insulation by own then I think only Batt insulation is one of the cheapest and best insulation material can be inserted by basic DIY skills.
Let me brief you on how insulation material help in sound deadening.
How Does Soundproof Insulation Works?
There is one misconception in between soundproofing and sound deadening, here soundproofing means improving the sound quality however sound deadening means blocking the sound transmission.
Soundproof insulations are mainly used to block the transmission of the sound waves where most of them are made of vinyl nitrile and having cells in its varieties of insulations while manufacturing.
So such Airwaves striking to the cells of the insulation and got dissipated its energy into the small amount of heat. Which in result no soundwaves left to pass through it and propagate further.
In such a way insulation helps us to block the unwanted noise coming from the unnecessary sources but be aware, it won’t help you to minimize the echos.
Noise and Echos are different things where echos generated due to the reflection of the soundwaves however noise, in general, is the mixture of different frequencies to learn more check our detailed guide.
Let me help you parameters which should check prior to buying any soundproof insulation.
How To Select Best SoundProof Insulation?
If you are concerned about the insulation, the quality of the products always matters as it helps to get you better and effective insulation, below are the few factors to take care while choosing insulation.
STC stands for sound transmission class which is a unit to measure the soundproofing ability of any material. Almost every acoustic product is labeled with the STC score between 1-100.
25 – Easily understood
30- Fairly understood
35- Audible but not intelligible
45- Must strain to hear
48 -Barely Audible
Which means the higher the STC, it is best for insulation and that is why it is recommended to have STC of 52 for bedroom wall to avoid unnecessary noise.
We all know the efforts and money required for any insulation to install and purchase, so it is better to search for those which are durable and have great positive reviews.
Durability will specify the ability of any insulation material to be effective consistently for a long duration of time.
In these parameters, you can check its ability to resistant flame, moisture absorption capacity or any rodent nature.
Price of insulation
We learned three types of insulation and the price of each type will be varied based on the quality it offers. While considering the price of spray foam insulation it will range around 30-60$ per square foot.
But in general Batt or roll insulation is cheaper as compared to foam spray and Blown-In, so it all up to you which one you chose for your what purpose.
So make sure to identify the area you want to cover with insulation if it is wide and large then probably batt insulation can be the cost-effective solution.
But if filling the floor in the commercial building then most builders prefer blown-in insulation.
Well, you got an idea about the major factors you need to validate prior to buy any soundproof insulation, let me highlight the best available batt insulation.
Best SoundProof Batt Insulation
There are 1000s of products available for Batt insulation, which are providing the best quality material from the customer end review perspective such as.
This is an air double reflective polyethylene insulation roll which has the ability to retain its air longer and provides excellent insulation and sound reflection.
Which is ideal for the attics, exterior or interior walls, floor, metal or still building and garage ceiling or many more other spaces.
This insulation roll is around 125 feet long,24 inches in height and around 0.03 inches thick. This also helps to maintain the heat inside the room which saves overall electrical energy.
For the end, customer reviews and price make sure to check out the below navigation link.
It is an acoustic mineral wool insulation with 6lbs per unit density. It is among the most popular acoustic insulation for soundproofing material.
It is available in 3 pieces of size 48″*24″*4″ each which is a rigid board perfect for acoustic panels and bass traps. This can be installed to the walls to reduce the sound transmission but be aware this can not help you to minimize the echos.

There are no limitations with the insulation products available, you have to create your best choice which fit for your need. If you learned everything then this time is to learn a few basics on how to install.
How To Install Batt Insulation?
Batt installation does not require any professional skills if you know DIY will be good enough to setup or install Batt insulation.
Make sure to identify the face of the insulation in case you have been able to identify and I imagine you want to place this insulation to your existing wall, ceiling or floor.
In all the three cases you have to follow the instructions given by the product company or below highlights general steps to install Batt insulation.
- Clear the room or any unwanted material which does not require during insulation.
- Cover yourself with hand gloves, shoes, goggles, and basic clothing to avoid any misfortune.
- Get scissor or any cutter for cutting the Batt insulation and do not forget to wear the mask.
- Identify the size of the wall or ceiling or cavity you want to fill using the Batt insulation, get exact or idea on length and width and height.
- Cut the Batt insulation into the defined size pieces where make sure to start from the edge of the roll or sheet to get a proper cutting of the insulation roll.
- Fit the insulation into the framing cavity and make sure to not push or press to avoid tear or damage with insulation.
- If filling behind the drywall then make sure to take help of the other people to give you the batt insulation and you can push that material to cover the entire space and using the staple gun can attach the paper lining to the wooden stud.
- In case you have any plumbing pipeline connections then cut the Batt into tow parts one place behind the pipe and other on top of that to make sure no cavity remains left.
I imagine you got an idea about the accessories you needed to set up batt insulation and a few general things to be cautious around the same time.
My View On Soundproof Insulation
In the late 1960s, people were using plaster walls as partition wall but now this becomes popular to have drywall which in result there are higher chances of sound or noise transmission from one place to other.
The best effective solution is by installing the soundproof insulation which fills the cavity and overcomes the issues of cavity walls.
Traditionally everyone uses Batt insulation as it is cheaper in price and easy to install but foam insulation and blow-in become popular in the area where you are concerned about the efficient soundproofing like music studios.
Quality will always cost you at a higher price, so take your better choice and decide the best out of it. If you have experienced any type of insulation before then please let our readers know your comment.
