AcoustiStep Rubber IIC Sound Mat

AcoustiStep Data Sheet AcoustiStep Specs

The Commercial Acoustics AcoustiStep is a highly engineered sound-damping underlayment that is designed to be installed underneath LVT, Laminate or Hardwood Flooring to create quieter living or working spaces throughout an entire location.

Designed to improve impact and footfall sound (IIC Ratings), the Rubber IIC Sound Mat dampens structure-borne noise by absorbing the vibrational energy before it enters the slab below.

Easily adhered to wood or concrete substrates, and available in 2mm, 3mm, 5mm, 10mm, and 12mm thicknesses, AcoustiStep Rubber IIC Sound Mat is tested on a number of assemblies to provide an IIC Rating of 50-64 (varies by flooring assembly and product thickness).

PART 3 – EXECUTION

3.1 PREPARATION

A. Inspect substructure prior to installation.

B. Follow the subfloor preparation instructions and recommendations of the flooring manufacturer.

C. Only qualified and structurally sound subfloors are to receive AcoustiStep.

D. Sweep, vacuum, and remove all debris from the subfloor prior to rolling out AcoustiStep.

1. Subfloor shall be free of solvents. Mechanically remove old adhesives and paints where applicable.

2. See specifications of manufacturer approved adhesives if glue-down application is required.

3. LVT/LVP:

2mm, 3mm: double glue down (AcoustiStep to subfloor and flooring to AcoustiStep).
5mm+: single glue down (flooring to AcoustiStep only).

E. Remedy any holes, gaps, or breaks that may exist in the substructure.

F. Vapor emissions from a concrete substructure not to exceed 5lb/1000sf in a 24-hour period per ASTM F1869.

3.2 INSTALLATION

Roll out AcoustiStep over the subfloor surface.
Splice each roll of underlayment at the seams with a film tape, duct tape, or other pressure sensitive tape.
Tape must meet or exceed the water vapor transmission standards suggested by the flooring manufacturer.
Connect rolls together evenly so that no overlapping or wide gaps between sheets occurs.
Trim material as needed to fit the floor surface area and avoid obstructions.
Proceed to finished flooring installation per manufacturer’s instructions.
1. Qualifies for floating, glue-down, and nailed assemblies.
