We are about to put the tiles on the radiant floor in our simple stone house. Do you have any recommendations? It's a radiant floor, nearly at the maximum thickness that the floor guy recommended. We used lime mortar (cal) instead of cement. And want to use mortar again when we lay the tiles. I have a very experienced builder doing the work.
Obviously we want to avoid chemicals, and use the most eco, yet durable option. Any thoughts on tile very much appreciated!
