Our Iso-Step® Floor Underlayment is engineered to provide superior impact sound insulation and better performance over other sound control materials. It may be installed over a wood or concrete sub floor and under a wide range of flooring finishes. Installing Iso-Step® underneath the entire flooring assembly short circuits impact noise to combat footfall and structure borne sound and vibration.

Impact noise is a structure borne sound created when two objects collide. This impact energy creates vibrations that resonate through the materials in the structure. It also creates airborne sound. This is often realized in the real world as a ‘neighbor noise’ generated from someone walking on the floor above or other activities. The Iso-Step® acoustic floor underlayment should be placed underneath the finished flooring and cover the whole floor. This provides an isolation layer to help prevent structural sound from passing through the completed assembly.

Manufactured in the USA using recycled material, this rubber floor underlayment has been rigorously field tested with proven results. It can be installed under most types of grouted, glued, and floating floors, including ceramic tile, stone, marble, brick, pavers, hardwood, engineered wood, laminate, parquet, luxury vinyl tile and carpet.

Our Iso-Step® Floor Underlayment is available in thicknesses of 2 mm, 5 mm, 10 mm and 12 mm. With a Delta IIC from 16 to 25, we offer a rubber floor underlayment well-suited to meet any job requirement.
