SheetBlok™ Sound Isolation Barrier is a dense, limp-mass, vinyl material that is used to stop the transmission of sound in a wall stack-up of materials. It acts as a thin, dense, sound barrier layer in walls, ceilings or floors, and is most effective when used as one component of a multi-layered construction scheme. SheetBlok™ is useful for decoupling (i.e. floating) floors and walls in isolation construction applications.
