Although closed-cell Versi-Foam® Systems are not technically an acoustical material (meaning they do not absorb sound), they can be used in the effort to control sound. As a closed cell foam, it will block the transmission of sound from one area to another. Therefore, spraying a layer of foam on an interior wall will muffle sound around loud rooms and maintain privacy in homes, offices, hospitals, schools, and libraries.
By spraying a layer of foam onto very hard surfaces, sound is reduced because the echo is reduced. For instance, a room with concrete walls and floors with a very loud piece of machinery can be a very noisy situation. The sound of the equipment will keep bouncing off the concrete surfaces. If you apply foam on the walls it will reduce the echo, and thus reduce the sound.
Because it is a closed cell, expanding sealant; caulking large gaps between areas can stop the passage of sound – along with air, dirt, and moisture.
Choose the Standard foam or the Class I foam for your specific application.
