Sound Control with Spray Foam Insulation

Although Foam it Green is not technically an acoustical material (meaning it does not absorb sound), it can be used in the effort to control sound. Foam it Green spray foam creates a seamless air barrier. An air barrier blocks the transmission of sound from one area to another.

Therefore, spraying a layer of Foam it Green on an interior wall will muffle sound around loud rooms and maintain privacy in homes, offices, hospitals, schools, libraries, etc.

By spraying a layer of foam onto very hard surfaces, sound is reduced because the echo is reduced. For instance, a room with concrete walls and floors with a very loud piece of machinery can make for a very noisy situation. The sound of the equipment will keep bouncing off the concrete surfaces. Foam on the walls will reduce the echo, thereby reducing the sound.

Because Foam it Green is a closed cell, expanding sealant, caulking large gaps between areas can stop the passage of sound, along with stopping air, allergens, moisture, etc.

“Very easy to use. Simple videos to watch and it was a walk in the park. Did not have to contact you for any help but you were there if needed. The green spray foam made it easy for installation and just like in the videos, just make sure it is green.

The foam sealed perfectly and added more insulation factor between the outer walls. I also used this as a sound barrier between two different rooms.”

“My husband (66) and I had been looking at the different products found your product to have the best value. Bought in December had to wait till March to spray. The ease of using this product was great for seniors. We sprayed the foam on the inside basement foundation where the wood sets on the concrete before you could see daylight. Now completely sealed no drafts and outside noise is gone. We are remodeling and will continue to use FOAM IT GREEN®.

Wind and daylight are gone since we sprayed. Noise level is great. Our basement is a lot warmer.”

“Remodeled a bathroom in a mobile home manufactured in 1969. First thing I noticed was that almost all the noise from the road disappeared. The difference was that drastic. Even the homeowner noticed the change when she walked into the room. Secondly, the temperatures dropped to below zero for the next few days, the water never stopped flowing, the homeowner even noticed that she was getting more hot water in the kitchen (the longest run) than she had before.

All in all, a great product, I can’t wait to use it on my own home.”

“We were building a soundproof wall for a therapist’s office. We used sound attenuating sheetrock and heavy hotel doors (double solid core doors hung on the same jamb) but we had a partition wall that didn’t mate with the second floor joists above it and there was no way to make them meet without a lot of expensive work. If only there was some way to fill the boxes where the first floor partition wall’s top plate ran perpendicular to the second floor floor joists.

I ordered the FOAM IT GREEN® system, the smallest size. Even so, when I had questions about application temps, staff answered them right away. They also returned my calls within the hour. I was really impressed with that.

I was very impressed with how easy the product was to use. And it sound proofed that last piece beautifully. It filled those big cavities with no problems. I would say it has to have an STC rating of well over 50.

My next project with FOAM IT GREEN®? Encapsulation of asbestos in the attic of my personal home.”
