999984 in stock




You’re ready to soundproof your home theater, garage recording studio or podcasting studio. Or, perhaps you have a commercial facility to soundproof, like a medical office or auditorium. Whatever your soundproofing job is, you have two concerns:

  • Finding the right product to capture all the echoes, reverberations, harsh noises and other low-, medium- and high-frequency sounds that could interfere with your environment
  • Making sure whatever product you choose meets existing building code regulations

If you have used soundproofing foam before, the first concern may seem easy to resolve. You may know polyurethane has excellent soundproofing qualities. However, you may also know it is not strong in terms of flame-resistance. This means if you are in a location with stricter building fire safety codes for exposed materials, you may have a problem.

Udderly Quiet™ Class A™ 1” Gray Anechoic Acoustic Foam is the solution you need. These are lightweight 2’ x 4’ panels of 1”-thick soundproofing foam in an unobtrusive gray color and appealing 3D double convoluted pattern. Unlike traditional anechoic acoustic foam, however, these 1” gray anechoic foam panels are made of open-celled acoustic melamine, rather than polyurethane.

Open-celled acoustic melamine is a remarkable substance that is highly heat- and flame-resistant. Not only this, it has powerful soundproofing qualities, with a Noise Reduction Coefficient equal to or greater than a similar polyurethane product.

With each case of 1” gray anechoic acoustic foam from Soundproof Cow, you get a full 18 panels, which means you can cover as much as 144 square feet of room with one case.

These foam panels are made in the U.S. to be long-lasting and reliable, featuring temperature resistance as high as 482 degrees Fahrenheit with the ability to withstand constant temperatures as high as 320 degrees Fahrenheit. Use these panels and enjoy a clean sound environment without worrying about the potentially damaging effects of sparks or heat extremes.
