Noise cancellation Acoustiblok

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).

Aboust Acoustiblok:

Acoustiblok’s sound insulation material 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.
