Rated 5 out of 5 by 1 reviewer.
Rated 5 out of 5 by Great Product, Easy Install and IT WORKS! Ordered this product to try underneath the new foyer cermic tile flooring to reduce both the foot traffic and area noise. Manufacturer's instructions state you can install ceramic tiles directly on product using epoxy adhesive/ grout products. Did not want to use the epoxy products as they are difficult to work with so installed underneath 1/4" hardiboard then installed ceramic tile using permabond thinset and enhanced grout. It looks beautiful and works like a dream. The noise is reduced considerably. So happy with this product that I will be using it underneath my new wall to wall carpeting throughout the upper levels of the house. Highly recommend this product to use when redoing your flooring. Its amazing and the manufacture's customer service and assistance was great. May 29, 2012
