Just enough insulation from slab.

Product minimizes heat loss from concrete slab on cold days. Product was grouted down first and then the element rolled out. Great at minimizing thickness of completed floor!

Works surprisingly well

I'll admit, when this arrived I was doubtful that it would do anything - it's pretty thin. But halfway through the CeraZorb underlayment installation on the basement floor, we could feel it working - definitely blocked the chill coming through the concrete! I'm certain this will keep the radiant floor heating in the room where it belongs, and not seeping down into the concrete below.

Just the right size for DIY

The sheets were just the right size for DIY. In hindsight, because the floor mats had the flat cable assembly, I could have safely gone with the Cerazorb instead. (increased R-value). Anyway, the cork provides a nice stable base for the mats and the hardwood floating floor.

Great product

Great product, would highly recommend if you are putting a heated floor over a concrete basement floor. They are pricey though if you need a lot.

Very impressed with the insulation value of these tiles especially for being only 5 mm thick.

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!

Quick warmth!

I'm sure the cork is in large part responsible for my tile floor warming up so quickly!

Exactly what I was looking for.

Pleased with the product and even more with your helpful service. Great doing business with you. I applied the cork on the wall behind my new refrigerator, using it as a sound absorber. I really don't have a before and after comparison, but just enjoy knowing that I made an effort to dampen the sound and found the product easy to cut and affix to the wall. The 1/4 inch thickness was satisfactory. Thanks for guiding me to finding and purchasing the underlayment. It's exactly what I was looking for. By the way, I have the same material on the wall behind my desk, and it makes a great bulletin board. I'm happy to have done business with you.

Response from WarmlyYours:

Thank you for your kind review, Gary! We're happy you found what you needed!

Flawless

It was easy to install. I placed it in position the night before the carpet guys were showing up to install the carpet. The installation process overall was flawless.

Performed up to all expectations

The synthetic cork Cerazorb product installed easily and provides a great base for the heating mats. \Our installation was over a concrete slab and the Cerazorb allows for quick heating and longer heat retention. It has performed up to all expectations. I would recommend it to anyone installing basement floor heating.
