In light of the restrictive regulations which now determine the minimum sound insulation properties in newly constructed buildings, Primary Acoustics LLC has introduced VERDEX® - a superior noise reduction solution for commercial properties and multi-family communities.

VERDEX® is an innovative acoustical floor underlayment used for reducing sound under ceramic tile, natural stone, marble and hardwood.

Made from 100% recycled rubber, VERDEX® is an environmentally friendly product that will not rot, support mildew or mold growth or absorb water. Various thicknesses, from 3mm to 20mm, are available to meet your specific acoustical requirements. Whether you choose rolls or panels, VERDEX® offers economical, fast installation over wood or concrete sub-floors in multi-family and commercial applications.

VERDEX® has achieved FIIC ratings of 60+ and exceeded the requirements of the ASTM C627 Robinson Test.


If you are working with a wood sub-construction and need to find a permanent sound solution for your floor/ceiling assembly, it's time to catch THE WAVETM.

THE WAVE is an acoustic underlayment that was specifically designed for commercial and residential construction over wood.

Like traditional VERDEX®, THE WAVE is made of 100% recycled rubber and utilizes a bonding agent that is odorless and colorless. THE WAVE has a flat surface on one side and a dimpled surface on the other. These undulations capture sound waves as they pass through the floor/ceiling assembly caused by footfall upstairs. The goal is to increase the Impact Insulation Class (IIC) of your building to comply with new sound regulations passed by the International Building Code. The result is a quieter environment for work, play and easy living.

Available in 6mm thickness with a 3mm dimple, and can be used under floated or glued laminate or engineered hardwood. The standard roll size is 5' x 25'.


CF3 underlayment is a high performance, durable PUR foam and cork blend that has been specially designed for use under resilient vinyl flooring.

CF3 contains no "crumb rubber" and will not cause the vinyl to discolor or become brittle.

Available in 3mm thickness, CF3 is lightweight - a 39' x 62' roll (201.5 SF) weighs only 60 lbs.
