    What is Soundproof Insulation? The main difference in Batt vs Blow-in vs Foam


    Soundproof Insulation

    Due to the evolving types of machines and daily traffic, it is becoming more and more popular in various countries to soundproof a house, private room, office, or car with use of soundproof insulation. But what are the benefits of insulation in soundproofing?

    Have you ever wondered what is the difference between in soundproofing and soundproof insulation, and why it is a bit confusing whenever people asking us to use soundproof insulation for soundproofing is confusing right?

    The soundproofing of any room can be done with many other products. Apart from these products, soundproof insulation is the most effective solution.

    This is an important part of soundproofing due to its ability to block sound waves thereby reducing side-to-side sound transmission and I would like to make it clear that it is used for soundproofing purposes rather than sound-absorbing.

    Do you see the difference between soundproofing vs sound absorbing? If not, be sure to learn from our complete detailed guide.

    I have the answers to all your questions about what is soundproof insulation and how it works, what is the best sound insulation on the market, and what prior to check before buying a sound insulation.

    What is Soundproof Insulation? Best Explain

    When we talk about sound waves, they travel faster than dense airspace. Which means blocking out unnecessary noise or sound. We need a strong barrier that will cause problems for the sound waves to pass through.

    You may have heard of drywall that sticks to vertical studs, leaving gaps between the vertical studs, making them a weak barrier and compromising your privacy on the other side of the wall.

    Insulation material is the best choice for filling the same gap. Usually, each wall is filled with insulation material to cover these voids and create a strong sound barrier from the other side of the wall.

    They are made of loosely packed fibers, mineral wool or cotton, etc. Of the three, standard fiberglass insulation is cheapest than mineral wool insulation but less effective for soundproofing.

    Most walls are factory fabricated and installed right on the construction site for easy, fast and low cost construction. However, it doesn't offer any quality in terms of soundproofing or confidentiality.

    To avoid this, insulation is often used to dampen sound waves flowing from one side of the wall. In addition, the heat in the room is maintained and electricity is saved.

    I think you got the idea to use some isolation. Let me help you classified what types of insulation are available?

    Types of insulation

    Soundproof insulations are different types and can be used for different purposes. Therefore it is divided into three parts.

    I've search various websites for an idea of ​​the category or types of insulations and here are a few.

    Batt or roll insulation:

    Batt insulation is built with fiberglass or rock wool and may be just as you might imagine. They come in several varieties, the thickness depends on your needs, but usually in flat pieces.

    Batt installations are usually installed between vertical wooden studs to fill in the cavities behind the drywall. There may or may not be a face.

    Batt insulation is built of tightly fiberglass woven strands that together form a matrix, and because of the multiple layers, it forms a strong barrier.

    This is one of the best home insulation materials out there, making it an ideal for older homes.

    Likewise, the roller insulation provided on rollers, not flat pieces, is built with the same type of material and both fall under the category of conventional insulation.

    The Blown-In Insulation

    This is another great type of insulation when comparing to Batt or Roll insulation. Blown-in insulation is built from a mixture of cellulose or loose fiberglass, so it cannot be installed with homeware solutions and must be used by professionals.

    In terms of insulation, it is similars to batt and roll insulation, but the blown-in insulation is non-toxic, and fireproof and absorbs less moisture seeping, which helps prevent rodents from getting into the insulation.

    The Blow-in insulation is treated, with boric acid and other substances, making it fireproof, and then packed in tightly packed bags.

    This insulation is mold and can easily fit in or reach any area compare to batt or roller insulation.

    It provides a higher R value (R value is a measure of insulations efficiency) than batt or roller insulation and is one of the most recommended solutions for filling pile wall cavities.

    It is a favorite among homeowners who prefer eco-friendly products because they are made from recycled materials such as paper and wood products and the chemicals are made through a synthetic process.

    The Spray foam insulation

    As the name suggests, it comes in the form of a liquid that can be inserted into any cavity and is one of the most popular types of insulation, ideally made by specially trained professionals.

    It has the ability to expand 100 times and then to true volume, which helps create an air tightness and fill any gaps that may exist in cavities.

    Due to its strong tightness, it leaves little room for air leakage and is therefore specifically used to fill ceilings, walls and floor cavities.

    Of the three, it is clear that blown-in and spray-foam insulation are some of the most popular and very effective, and even expensive, insulation solutions.

    If we only talk about insulation, then I think only batt insulation is one of the cheapest and best insulation materials that can be used through basic DIY skills.

    Let me briefly introduce how insulation materials help reduce noise.

    How does Soundproof Insulation works?

    There is a misunderstanding between soundproofing and sound deadening. Here, soundproofing means improved sound quality, but sound deadening means blocking sound transmission.

    Soundproof insulations is mainly used to block the transmission of sound waves when it is mostly made of vinyl nitrile and has cells in the insulation type during production.

    Such airwaves hit the insulating cell and dissipate a small amount of heat energy. As a result, the sound waves cannot pass through and spread further.

    In this way, isolation helps us block unwanted noise from unnecessary sources. However, note that you cannot minimize echo.

    Noise and echo are different things in which echo is generated due to the reflection of sound waves. However, noise is generally a mixture of different frequencies. For more information, check out our detailed guide.

    Let me help you with the parameters you need to check before purchasing soundproof insulation.

    How to choose the best sound insulation?

    Whenever you are worried about insulation, the quality of the product is always important as it will help you to get better and more effective insulation. Below are some of the factors to consider when choosing insulation.

    Higher STC:

    STC stands the sound transmission class, which is a unit of measurement for the sound insulation performance of a material. Almost every acoustic product is marked with an STC value between 1 and 100.

    The higher the number, the better the soundproof insulation or soundproofing, According to the insulation institute, they have determined the capability of each insulating material in the STC number.

    25 - Easy to understand

    30 - Of course it's good

    35- sound, but incomprehensible

    45- You must make an effort to listen

    48 - It's hard to hear

    50- didn't hear

    That is, the higher the STC, the better the insulation. Therefore, it is recommended to use STC 52 for bedroom walls to avoid unnecessary noise.


    We all know the hassle and money it takes to install and buy insulation. So your best bet is to look for one that is durable and has excellent positive reviews.

    Durability determines the ability of an insulation material to be effective over a long period of time.

    Based on these parameters, you can check the resistance to fire, moisture absorption or any kind of rodent.

    Price of insulation:

    We have identified three types of insulation and a price for each depending on the quality offered. If you factor in the cost of spray foam insulation, it can range from $ 30 to $ 60 per square foot.

    In general, however, batt or roll insulation is less expensive than foam spray and blown-in. So it's up to you which one to choose for what purpose.

    So make sure to indicate the areas you want to cover with insulation. If these are wide and large, batt insulation can likely be an inexpensive solution.

    However, when filling floors in commercial buildings, most builders prefer blown-in insulation.

    Well, you have an idea of ​​the main factors that you need to confirm before buying soundproof insulation. Let me highlight the best batt insulation.

    Best SoundProof Batt Insulation:

    There are 1000 batt insulation products that provide the highest quality materials for customer evaluation such as:

    Reach the barrier:

    This is a air reflective polyethylene insulation roll which can hold air longer and has good sound insulation and reflection.

    How do I install batt insulation?

    Batt installation requires no professional knowledge once you know enough DIY to set up or install Batt Insulation.

    Be sure to identify the surface of the insulation if you come across and can imagine that you will want to apply this insulation to an existing wall, ceiling or floor.

    In all three cases, you will need to follow the product company's instructions or highlight the general steps for install Batt insulation below.

    1. Free up unwanted space or materials that are not needed during insulation.

    2. Cover yourself with gloves, shoes, safety glasses and basic clothing to avoid accidents.

    3. Use scissors or another knife to cut the batt insulation and put on a mask.

    4. Determine the size of the wall, ceiling or cavity you want to fill with Batt insulation and get an accurate picture of the length, width and height.

    5. Cut the batt insulation into sections of a certain size. Make sure you start at the edge of the roll or sheet of metal to get the correct cut of insulation.

    6. Place the insulation into the frame, being careful not to squeeze or squeeze so that it does not crack or damage the insulation.

    7. By filling in the back of drywall, you are helping others provide you with bat insulation. You can press this material to cover the entire room, and with the help of a stapler you can attach the liner paper to the wooden posts.

    8. If you have plumbing, cut the batten in half at one point behind the pipe and another at the top to make sure there are no more voids.

    I think you have an idea of ​​the accessories you will need to adjust bat insulation and some general things to keep in mind at the same time.

    My Opinion on sound insulation

    In the late 1960s, people used plasterboard as partitions, but now it has become popular to have drywall, which results in a better chance of transmitting sound or noise from one place to another.

    The most effective solution is to install soundproof insulation that fills the cavities and solve the cavity wall problem.

    Traditionally, everyone has used batt insulation because it is cheaper and easier to install, but foam insulation and blow-in are becoming increasingly popular in areas where you are concerned about effective soundproofing, such as music studios.

    Quality always costs you a higher price. So make better choices and choose the best. If you have experienced isolation, please share your comments with our readers.
