Auralex SheetBlok. Construction Sound Barrier. 4’ x 30’ x 1 Roll. SheetBlok Sound Isolation Barrier 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. SheetBlok is useful for decoupling (i.e. floating) floors and walls in isolation construction applications. Technical Details: Size: 4’x10′ rolls (40 sq. ft.) or 4’x30′ rolls (120 sq. ft.)
