Rado; I am afraid I may have confused you more with my second communication. Here is the KISS method which is; keep it simple stupid ; me, of course being the stupid one. Picture an igloo shaped dome sitting on a rectangular base.

In the dome on the oven floor or hearth a Pizza is cooking. Two feet above the pizza the layers are; stainless, insulation, refractory cement, more insulation and then topped off with more cement. Approx 5" total. Under the pizza is a course of fire-brick on the flat, then a layer of1/4" insulation board. Under that 1'' insulation blanket, then 1" insulation blanket. Finally supporting all that is 1/8" steel plate . I have two 3" stainless tubing pcs for venting which is right over the door. The oven door is 22" wide and 14' high half moon shaped at the top.
