Acoustiwool underlayment is installed under wood or tile flooring as an integral component of floor/ceiling sound dampening 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.
Achieving the unique balance of structural strength with resilient sound dampening characteristics this is the ideal product for use with tile floor finishes. This 0.11" thick material is manufactured with 85% Recycled content has an antimicrobial treatment to prevent mold. For use beneath ceramic and porcelain tile flooring. Acoustiblok® 16 oz. with Acoustiwool-TF0.11 are Robinson Floor tested and rated "Residential" by the Tile Council of North American.
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.
