 SheetBlok Sound Isolation Barrier from Auralex is a dense, limp-mass vinyl material that is about 6dB more effective than solid lead at stopping the transmission of sound. 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.
 
The product is available in a 30 x 4 foot roll and helps in decoupling (floating) floors and walls. And while it’s not normally considered a finish product per se, it can be painted with latex paint. Additionally, Studiofoam 1″, 2″, 3″ or 4″ panels can be wall mounted on to the SheetBlok Sound Isolation Barrier with Tubetak adhesive.
