AcoustiWool underlayment is installed under wood or tile flooring as an integral component of floor/ceiling noise abatement designs using Acoustiblok material.

The Acoustiwool-WF01.25 has been designed for use beneath hardwood, laminate and engineered wood floors. Used for wood floor finish installations only, on concrete or wood sub-floors beneath the Acoustiblok. Acoustiwool -WF0.125 works to decouple and isolate the top floor surface from the subfloor. The 1/8" thick wool composite is lightweight, flexible and easy to work with. Acoustiwool -WF0.125 is available with or without a moisture barrier laminated to it. Both have an antimicrobial treatment to prevent mold, extremely resilient, long lasting, and won't break down like air pockets in foam products.

About Acoustiblok:

Acoustiblok® is a 1/8 inch 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 one 1/8 inch layer of Acoustiblok in a standard wall will result in more sound reduction than 12 inches of poured concrete.
