Amazing!

This product is great. My radiant flooring grid would not have worked AT ALL if I hadn't used your CeraZorb mats. I tested the insulation properties by standing barefoot on my cold concrete floor. Then I stood on your product & the difference was AMAZING. I felt absolutely NONE of the coldness of the concrete. Thank you for coming up with this underlayment!
