electric radiant heat under marble


The marble is left over from a previous failed DIY project, and I've decided electric radiant heat would be the best heat for his room. I am redoing an enclosed porch off the master into a mini-nursery, then eventually sun room/green house. It is over an unheated root cellar, so I am wondering about insulating the sub-floor. Are there insulating backer boards? would some 1" foam board hold up between the sub-floor and backer board?

Your safest bet is to insulate it from below---in the root cellar.

Foam board under the backer board is not a safe installation--

That is an expensive installation with heat mat---failure is not an option here.

I thought they used that stuff under concrete slabs?

Yes they do----and under a slab is fine---If the backer board was 4 inches thick that might work

Backer board is pretty flexible----
