More than ever before we are experiencing disturbances in our work and personal lives. Such noise pollution can affect not only our peace of mind but also tension levels, communication between people, and even safety in the workplace.

Condo owners are becoming aware of low EPA and EPC noise standards, allowing easy litigation against sellers and builders for noise levels from adjoining units. (residential is 55 db at night, 60 db during the day)

It is of course much easier to head off the problem during construction rather than correct it (if even possible) after. OSHA is focusing more on noise levels in the work place than ever before. The cost effective solution, is to stop noise problems before they happen.

Today’s construction techniques leave much to be desired in these areas. The best acoustic isolation methods (rooms within rooms) are too costly to be put into the plan at the inception.  It is important to understand that contrary to common usage, fiberglass, foam insulation, sound board, or extra layers of drywall do little to stop noise transmission. Even a concrete block wall is not a very good barrier for sound.  A solid surface such as drywall, (including multiple layers), or even a block wall will absorb little acoustic energy. Solid rigid materials actually tend to vibrate themselves producing sound on the other side.  To control sound, walls must have the ability to absorb acoustic energy.

Acoustiblok® however, works as a sheet of soft lead does. It has tremendous density and mass (1 or 2 lb per sq ft), and it is installed loosely when possible; thus it absorbs the acoustic energy far better than solid ridged materials. 

Acoustiblok®, is not only an incredible sound isolation product, but can be easily installed without construction changes and is U.L. approved for use in 277 fire-rated wall and floor/ceiling configurations.

Acoustiblok® 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). 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 (see "Riverbank Lab" test results below). 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).
