There are some areas where quality soundproofing is a must. Podcast studios, music studios, home theaters and certain medical facilities are just some of the places where unwanted low-frequency sounds and echoes can ruin the environment.

For some of these locations, traditional polyurethane soundproofing foam can do the job. However, if you are soundproofing an area that gets a lot of traffic or where sparks or flame are a possibility, polyurethane may not be a safe option. Polyurethane is not particularly flame-resistant, and your local building fire codes may not allow polyurethane soundproofing foam under their regulations for exposed materials.

Our Udderly Quiet® Class A™ 1” white anechoic acoustic foam is perfect for this situation. These are 1” thick, 2’ x 4’ 1” white anechoic foam panels made from open celled acoustic melamine, not polyurethane. You get 18 with each case, allowing you to cover a full 144 square feet of room with quality soundproofing.

This bright white, aesthetically pleasing foam in an attractive 3D double convoluted pattern is much more heat-resistant than polyurethane thanks to the chemical properties of open-celled acoustic melamine but will still offer the same soundproofing power. Tests show that the Noise Reduction Coefficient of our melamine foam is equal to or greater than that of a similar polyurethane foam panel.

You can expect our Class A™ 1” white anechoic foam panels to meet most building fire code regulations, even those that require a Class A™ rating for exposed materials. The panels are very easy to install using basic tools and a standard construction adhesive, and you can count on them to last.

Rely on the temperature resistance of Udderly Quiet® Class A™ Anechoic Acoustic Foam with confidence. It is heat-resistant to 482 degrees Fahrenheit and can withstand constant temperatures up to 320 degrees Fahrenheit.

The times I talked with you on the telephone and corresponded through email you have been very helpful and efficient. I would highly recommend Soundproofcow.com to anyone!

– S. Cimino, PA

I have emailed a lot of different manufactures and I have to say your customer service is head and shoulders above all of them. I emailed your company at about 9pm my time and when I woke up the next morning you had already answered my question and then the follow up was a few hours later. I am impressed. Thanks a lot for the quick turn around!

– E. Gustafson, NV

I just wanted to send a quick thank you for your rapid response and helpfulness. I very much appreciated it. You have been responsive in every way all through the process. It has been a pleasure doing business with you and your company.

– T. Alexander, CA

I just wanted to let you know that in the end, sealing the air spaces on this door worked just fine and took care of the problem.

I really appreciate you taking so much time to share your expertise with me, and in particular recommending I try the simpler solution before investing in more expensive noise barriers. That is a big credit to you and your business.

– Mike
