I've got an uninsulated concrete floor in my kitchen which I want to have Travertine tiles laid over, the tiles will continue into an extension which has an insulated slab with the same FFL I'm wondering if there is an ultra thin insulating material that can be put between the uninsulated concrete and the tiles. I'm thinking that 4mm exterior ply would give some thermal break if it was stuck to the concrete but would this cause problems with the travertine do you think?
