Udderly Quiet™ Class A™ Anechoic Acoustic Foam 4″ White (Case of 4)

999999 in stock




You know you need serious soundproofing power in an acoustic foam panel for your recording studio, theater, auditorium, classroom or other sound-sensitive environment. The problem is that you are located in a facility where fire hazards abound and building fire codes for exposed materials are strict. What can you do?

Our Udderly Quiet™ Class A™ 4” White Anechoic Acoustic Foam is as much sound absorbing power as we can give you in a flame-resistant foam panel. Each case contains four 2’ x 4’ panels of four-inch thick open-celled acoustic melamine. Our open celled acoustic melamine delivers a Nose Reduction Coefficient comparable to our polyurethane foam but has much greater fire and heat resistance.

This product offers heat resistance up to 482 degrees Fahrenheit and can stand regular temperatures of 320 degrees Fahrenheit. It is not likely to combust when struck by random sparks and can meet building fire codes that require exposed materials to be Class A-rated. At the same time, this foam will gobble up all that unwanted bass, echo and other harsh sounds that are interfering with your recordings, conversations or presentations.

These bright white panels cover 32 square feet with each case with an aesthetically pleasing 3D double-convoluted pattern that fits into the environment while protecting you from harsh sound. They are simple to install, requiring only a tape measure, level, pencil and construction adhesive. You can soundproof an entire room with these panels in a matter of hours.

These are durable, reliable anechoic foam panels made in the U.S.A. and built to last. You are sure to be impressed with the dramatic improvement in sound quality you experience when these panels are in place. Each is a consistent density, so you will enjoy the same clean sound throughout the entire room.

Don’t deny your theater, studio, gym, office, school, auditorium or other facility the soundproofing it requires because you are concerned about building fire safety codes. Find your solution by ordering your cases of Udderly Quiet™ Class A™ 4” White Anechoic Acoustic Foam now.
