My Floor has angle iron, cement with rebar and then 3 inches of calsil slabs for insulation. I am about 1.25" to deep and will be using 3"x24"x12" firbrick slabs for the floor of my oven. To raise the level the 1.25", is there any health or safety issues using cement board to place my firebrick on versus a cement/clay mix.
