Acoustiblok® is typically applied as part of layered wall, ceiling or floor construction. It is usually stapled to wood studs or screwed to metal studs prior to drywall. Each layer of 16 oz Acoustiblok reduces sound transmission by as much as 30 db depending on the frequencies. It has more sound deadening effectiveness than some treatments with lead. A typical 2 x 4 gypsum stud wall is usually 33 to 35 STC. Acoustiblok installed in the 2 x 4 wall is lab certified at an amazing "STC of 52", better than 12" of poured concrete (STC 51).
Acoustiblok's U.L. Classification file number is R21490 and it is approved for use in over 350 wall and floor/ceiling assemblies.
Acoustiblok audio specifications (STC, NRC, IIC) are independent laboratory test results by Riverbank Acoustical Laboratories, NGC Testing Services, and Intertek ETL/Semko. Original reports are available from your Acoustiblok sales representative on request. Don't put your project at risk by relying on uncontrolled vendor "field test" or self test results - insist on hard numbers from certified independent laboratory tests, when specifying acoustical solutions.

Acoustiblok offers high performance sound reduction solutions for multifamily projects, condominiums, hotels, hospitals, construction sites, industrial areas and other projects where privacy and sound control are important.
Acoustiblok is a heavy, yet very flexible viscoelastic polymer material that provides sound reduction through a unique adiabatic process. Rather than attempting to block or absorb sound, Acoustiblok transforms sound energy into inaudible friction energy as the material flexes from sound waves. A 1/8" (3 mm) thick layer in a single stud wall assembly (STC 53) can provide more sound reduction than 12" (305 mm) of poured concrete (STC 51). Acoustiblok is UL classified for wall, floor and ceiling fire-rated assemblies; it is nailed or stapled to wood framing or screwed to metal framing prior to drywall, ceiling or floor installation.
