You want a soundproofing solution that fits in with your recording studio, home theater, professional auditorium or other sound-sensitive environment while also providing effective protection against heavy bass, unwanted echoes, reverberations and other harsh sounds. On top of this, you also want the material to adhere to strict building codes for fire safety.

Although it may sound impossible, Soundproof Cow has done it, thanks to our Udderly Quiet® Class A™ 3” White Anechoic Acoustic Foam. These three-inch-thick foam panels contain plenty of soundproofing power, so much so that it may surprise you to learn they are not made of polyurethane.

While we love polyurethane, we know it does not have the same flame-resistant qualities of some other materials, which means certain buildings may not allow polyurethane foam under their fire codes for exposed materials.

The solution we came up with is to make these 3” white anechoic foam panels out of open-celled acoustic melamine. This miraculous substance has a Noise Reduction Coefficient comparable to polyurethane, but with a Class A fire-rating that gives it tremendous heat and fire resistance and allows it to meet those stricter building codes.

You don’t have to worry about stray sparks or temperature spikes igniting these panels, which can resist constant temperatures up to 320 degrees Fahrenheit and can stand temperatures as high as 482 degrees Fahrenheit. The bright white 3D double-convoluted design of these panels is architecturally interesting, functional and a great fit for your noise-controlled environment. Five 2’ x 4’ panels in each case cover as much as 40 square feet of surface.

You’ll have no difficulty installing these panels in your studio or other facility, as only simple tools and basic construction adhesive are required. You can have them up right away, so they are benefitting you and your work immediately.

You don’t have to sacrifice soundproofing just because your theater, studio, gym or office is located somewhere with strict building fire codes. Beat the system by ordering Udderly Quiet® Class A™ 3” 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
