Topic: Recommend Thickness of Materials Above Product?

Ryan,

Sorry for not having replied sooner, we have been going through some system changes as of late.

Honestly, what you suggest will most certainly adversely affect the system. Considering that tile is generally anywhere from 1/4 to 1/2 of an inch thick along with the thinset that is at least a suggested 3/8 inch thick and although this is beneath one inch thick, the system can only handle a total floor thickness above it of one inch before the heat output of the system is greatly affected.
A flooring thickness of over one inch above the system will still receive heat, however the thicker the flooring, the more heatloss you will receive.
Let us know if there is anything else we can help answer for you! Thanks Ryan!
