Acoustiblok

Acoustiblok is a unique 1.1 lb. psf U.L. Classified, high S.T.C. reinforced dense noise isolating material which is utilized as a structural treatment for reducing sound transmission. It contains no lead or asbestos materials.It is specifically formulated to meet rigid requirements such that is approved by U.L. for walls, ceilings and floors (see U.L. classification), also U.K. tested "B.S. 476: part 7". Acoustibloko 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 Acoustibloko reduces sound transmission by as much as 30 db depending on the frequencies (see "Riverbank Lab" test results below). 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).
