I hope I haven't mixed anything up or twisted it.
But probably misunderstood me?
I said: with the same type and thickness of insulation material, it almost doesn't matter whether it's only outside or distributed on both inside and outside, and with the same thickness of concrete or cellular brick, the overall result is always worse for concrete than for cellular brick.
I will not read all conceivable apples-and-oranges comparisons in the world, since I am not looking for the answer to the question "how much A + x results in the same or a lower U-value with the same or lower total wall thickness compared to which B + y."
Anyone who could only afford their house under the condition of minimized wall surface area should, by the way, actually be advised against building a house at all by a responsible financial advisor.
