Our Iso-Step® Perimeter Isolation Strip is used with Iso-Step® Underlayment to break the path of vibration transmission between the floor and the wall. The product is extremely flexible, lightweight, easy to install and handle. The material is sold by the roll, 2.5″ wide x 50′ in length and 6 mm thick. The Perimeter Isolation Strip is packaged on a roll for long placement runs and limited cutting.

The Iso-Step® Perimeter Isolation Strip should be installed at the perimeter of all areas receiving the Iso-Step® Floor Underlayment. It should also go around any protrusions in the flooring. This procedure isolates the sound mat floor system from other material.

This isolation strip creates an acoustical break to minimize the transmission of sound laterally from the “floating floor” to any other construction assembly. Adhere the foam perimeter isolation strip to the wall and trim off excess material once finished flooring is installed.
