Acoustiblok 1/8″ (3-mm)

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 3mm 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® 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.

About Acoustiblok:
Acoustiblok® is a 3mm thick proprietary viscoelastic polymer material with a high density mineral content, heavy and yet extremely flexible. As sound waves cause the Acoustiblok material to flex, internal friction occurs (isothermal/adiabatic) and the acoustical energy is dissipated into undetectable trace amounts of heat. A 3mm layer of Acoustiblok in a standard wall will result in more sound reduction than 12 inches of poured concrete.
