Is Spray Foam Insulation Good for Soundproofing?
Getting tired of hearing every little sound coming from the next room or outside your house? You can enjoy more by using soundproofing spray foam in your home, office, or room. A spray foam insulation system keeps noise out at all times and maintains a constant temperature.
In this article, we will discuss what spray foam soundproof insulation is about, the science behind soundproofing, and the benefits of spray foam sound insulation.
What is Spray Foam Soundproof Insulation?
Spray foam soundproof insulation uses polyurethane foam insulation to reduce noise in buildings. Spray foam insulation is a good choice for soundproofing because it helps absorb noise. Spray foam is applied to walls, roofs, ceilings, and building floors to dampen the sound coming from outside. For example, soundproof insulation for floors is done using spray foam to reduce noise between floors in a building.
How Does Spray Foam Soundproof Insulation Work?
Spray foam soundproof insulation helps create a soundproof environment by creating a barrier that stops noise from entering. Spray foam insulation seals gaps, holes, and leaks that can cause noise from entering or leaving your house. Spray polyurethane foam is an excellent choice for soundproofing as it expands to seal every hole and crevice that can lead to the transfer of soundwaves between your home and the surrounding environment.
Soundproof insulation foam can be applied to different areas in your home, like the roof, attic, walls, and basement, to make your home energy efficient and absorb sound waves. A typical example is sound insulation for windows, where polyurethane foam is applied to reduce noise.
How Can Spray Foam Insulation Help Reduce Noise Pollution?
Spray foam insulation can help reduce noise pollution by sealing your space air. In addition, spray foam insulation is effective in sealing hard-to-reach places that would have caused noise transmission in your home.
The Science of Soundproofing
A good understanding of the science of soundproofing will make you realize how sound is being transmitted and how spray foam insulation is a good way to reduce its transmission. A sound is a form of energy, and its intensity is measured in decibels (dB).
Sound energy travels in waves through the air. As sound travels outward from a source, it vibrates the air as it moves and hits the eardrums. As soon as it hits the eardrum, it is transferred to the brain, where the sound is being interpreted. Therefore, as sound travels from its source, the intensity naturally reduces, and it becomes less audible as you move away from it.
Soundproofing works in two simple ways; by moving away from the source or creating a barrier that can stop or absorb the medium through which sound waves travel - air. For example, spray foam helps to soundproof apartments by absorbing the soundwaves that would have otherwise passed through tiny edges or spaces in the house.
The Benefits of Spray Foam Soundproof Insulation
The best soundproof insulation is spray foam because it offers high-quality soundproofing. The benefits of spray foam soundproof insulation include the following:
Spray foam sound insulation improves your home's comfort by reducing unwanted noise from your surrounding. For example, if you stay in a noisy environment or along a busy road, soundproof spray foam will absorb the noise coming from outside and make your home peaceful and comfortable.
Spray foam insulation makes your home energy efficient by regulating the temperature. Spray foam insulation reduces the energy needed by the HVAC system to maintain a comfortable environment by making your home air-sealed, reducing air filtration into your home significantly.
Apart from reducing external noises coming into your home, spray foam reduces noise transmission between rooms and floors. In addition, sound insulation for walls and doors helps you achieve a quiet study room or a home office.
Spray foam sound insulation eliminates moisture buildup in your home. This helps reduce drafts and improve the air quality in your home.
Which Type of Spray Foam is Better for Soundproofing?
Spray foam has two types; open-cell spray foam and closed-cell spray foam. This article on Open Cell Spray foam vs Closed Cell Spray foam talks about the difference between both types of spray foam and their peculiar benefits. Here are the highlights;
As the name implies, open-cell spray foam is made up of cells that are not completely closed, making them soft and flexible. Open-cell spray foam is porous in nature, making it an excellent sound absorbent.
Closed Cell Cell
Closed-cell spray foam has completely closed cells. Compared to open-cell spray foam insulation, closed-cell spray foam insulation is dense and more rigid. Closed-cell also offers a higher R-value than open-cell spray foam insulation. Closed-cell spray foam is also a good option to reduce the transmission of sound waves.
Open Cell vs. Closed Cell for Soundproofing,
The porosity of the open-cell spray makes it a better option for trapping sound than closed-cell spray foam. Open-cell spray foam insulation offers better soundproofing for structures as it dampens soundwaves effectively than closed-cell spray foam.
FAQs About Soundproof Insulation

Let customers speak for us
This is really my first time spray foaming a whole wall but this kit is pretty simple to use I haven’t finished yet and I did waste some so will probably be ordering a few more cans but the calculator seems to get you pretty close perhaps order extra can or two if this is your first time. The product seems to work great for insulating walls for remodeling my plan is to do a room at a time I have started in our guest bedroom then will move to our master bath and bedroom taking Sheetrock down spraying the walls and remodeling I feel this kit in this remodeling environment works better then having a foam insulation contractor just come do one room at a time.
works well, sprays out easily BUT remember to cover up, wear coveralls or long sleeve shirt it will make things easier on clean up
Product worked as described. Easy to use. Does not cover a lot of area with one can. Use for small jobs
I’m fully satisfied with my first time spraying Fastcoat Insulation Spray Foam into an old uninsulated wall. I had used another great product to spray foam into the same wall, and it worked well but required simultaneous mixing of two products under specific conditions. Needed the KrakenBond foam to finish the job, and it was so much easier to use and came with a great spray gun and nozzles that made the job simple and successful.
Worked great for the area I needed. Wry impressed!
This stuff is amazing and will always be my go to from now on!
It works pretty well on OSB sheathing but on metal tin you'll have to be sure to watch out for the Sunnyside getting to warm and bubbling up and not sticking very well. Otherwise I'd say I'll do better next time.
Had to insulate pvc pipes for furnace in attic’s. Work amazing turned a day of work into an hour
System worked well, applied quickly and easily
Works pretty great. Even when you mess up you can trim up after curing easily. When spraying overhead you will get little dots on you so use the goggles they send and wear the suit or paint clothes or something. Proper distance is key but overall I think it’s a great product and am working my way around the shop case by case. I’d recommend buying an extra can or two of the cleaner so there’s no issue with the gun. The gun is much better than I expected.
So far so good had to buy a few more cans to get to the 2 inches. Doesn't stink, no to messy
First of all I do not work for Krakenbond or any company I mention in this review.
Definitely use gloves saftey glasses and old clothes or disposable coveralls. This is a messier than dow froth-pak or vegabond ( see pictures of hoodie and glasses). Maybe if it came with better instructions on how to use and adjust the gun not so much blowback. I watched a video were they said to wet the area down to help expansion ( see pictures) the area i misted seemed to develop holes compared to non misted areas could be user error it was the first can. I easily achieved the board foot and thickness the stated which makes this a great deal for my situation of remodeling one room at a time. I would recommend getting 2 cans of cleaner, 1 to spray the tip and one to screw on the gun. screwing on and off the spray nozzle with gloves is doable but a pain. I was skeptical of the tips staying on never had a problem with anything, just wish better instructions there is a learning curve. This product does seem to take a little more time to set/cure than vegabond or dow froth pak (see pictures of finger print marks) also the product seems softer than normal closed foam more on the lines of a window/door foam by greatstuff.
I am very pleased with the product and price and would recommend to everyone. For those reviews were people say it would take 200 cans to do my garage it doesnt matter the price breaks down to $1.12 a square foot, if you want to get dow froth pak 200 at $389.00 at lowes which is basically $2.00 a square foot because it has less cans be my guest its your money.
Kraken spry foam was used on two different application. Traditional application on the walls of our business and it turned out excellent. The second application was for a 300 gallon bait tank that need to hold a specific temperature. The tank is odd shape and this spry foam worked excellent for the application! amazing stuff!
This did exactly what it was supposed to the cans ran down right to the end the expansion was spot on and the coverage was good
