What is the difference between acoustical foams?
Common acoustical foams are usually open cell, urethane or polyester expanded foams. Because they are open cell, they absorb and pass sound readily. Usually they are used to condition a room which has bad acoustics, such as reverberation due to reflective, hard surfaces. Closed cell foams, such as our “Super Soundproofing Mat” absorbs readily but does not pass sound easily, making it a good barrier as well. Made of vinyl-nitrile, it will not absorb odor and has excellent moisture and fire resistance. Some think it’s the same as neoprene- it’s not!
