Good soundproofing is crucial for a variety of personal and commercial environments. If you are attempting to record an album or podcast, giving a performance or even delivering a speech, harsh noises, reverberations and echoes can ruin the experience. You need a reliable soundproofing product that can absorb all frequencies of unwanted sound to allow clear recording and communication.

For some environments, you may have another problem, which is meeting local building fire code regulations for exposed materials. Conventional wisdom is that the best foam for absorbing multi-frequency sound is polyurethane. However, while polyurethane can have many positive qualities, great fire and heat resistance are not among them. If your studio, theater or other facility has stricter building fire codes, you need a Class A rated solution.

That solution is Soundproof Cow’s Udderly Quiet™ Class A™ 2” White Anechoic Acoustic Foam. These are 2”-thick, bright white anechoic foam panels that are great at sound absorption, but made of Class A open celled acoustic melamine, not polyurethane. This means you get an equivalent or better Noise Reduction Coefficient but with superior flame resistance.

Each case from Soundproof Cow comes with eight 2’ x 4’ 2” white anechoic foam panels. This gives you sufficient coverage for 64 square feet of space. The panels have a clean, distinctive 3D double convoluted pattern and are carefully designed to have a uniform density, so you get evenly clear sound throughout the room.

Made in the U.S.A. and designed to last, our 2” white anechoic foam panels offer a constant temperature resistance of up to 320 degrees Fahrenheit and are capable of withstanding temperatures as high as 482 degrees Fahrenheit. They are just what you need for sound-sensitive environments where sparks, high heat or flame are possibilities.

Don’t put all your plans for a studio or theater on hold just because of strict building codes. Get the soundproofing power you need in a Class A flame-resistant soundproofing product by ordering your cases of Udderly Quiet™ Class A™ 2” White Anechoic Acoustic Foam today.

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
