When soundproofing your home theater, recording studio or podcast studio — or even a larger venue like an auditorium, gun range or warehouse — you need to consider many factors. The first, of course, is which soundproofing materials or products will be most effective at trapping and absorbing the types of sounds that may be interfering with your activities. The second is whether your material meets building fire code regulations for exposed materials.

With Soundproof Cow’s Udderly Quiet™ Class A™ 2” gray anechoic foam panels, you have both of these considerations covered. These 2” gray anechoic acoustic foam pieces are designed to capture low-, medium- and high-frequency sounds, so you never have to worry about screeching, bass noises or echoes interfering with the sound quality of your environment.

At the same time, the Class A™ rating means you can use this foam almost anywhere, even in buildings with strict fire code regulations. These panels are made of open-celled acoustic melamine, not polyurethane, giving you equivalent noise reduction quality to polyurethane but with superior flame and heat resistance.

A case of eight of these 2” thick, 2’ x 4’ Class A™ anechoic acoustic foam panels in a neutral gray that blends in with your environment can cover 64 square feet of space with a solid 2 inches of soundproofing power. The panels are designed to give you the same, smooth, consistent density with each panel, so you will get uniformly clean sound throughout the room.

These panels are proudly made by experienced professionals in an American factory and are built to last for years. Their temperature resistance is as high as 482 degrees Fahrenheit with an ability to withstand constant temperatures up to 320 degrees Fahrenheit.

If you have been putting off soundproofing your studio, theater, gym, medical facility, classroom or other sound-sensitive facility because of problems with building fire codes, you don’t need to put it off any longer. Order your case of eight Udderly Quiet™ Class A™ 2” gray anechoic acoustic foam panels right now.

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
