CZRG-SH5MM-48X48 reviewed by John O. of Seven Valleys, PA

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.
