Cold climate dome thickness

Could anyone tell how thick air-crete bricks should be to give good insulation
in really cold winters?
-
We need more info - in Vermont I've seen winters with weeks of below zero F. In Alaska that could be mild. In Mississippi that would be unheard of.
So - Where?

@gemniii do you have a structure of air-crete in Vermont? I'm in Missouri so we get wind, cold and wet in winter and wind, very hot and wet in summer. I did read about not putting vapor barriers on both sides. Looks like this could limit four season use. Opinion? Thank you.

@gemniii I'm in easternTN. Don't think it gets as cold as Vermont.
-
As far as I have read, aircrete has an insulation rating of 3.9 per inch. Is this true? Can someone confirm this please?
-
Please see What is AirCrete's R-Value? on the DomeGaia website. It's the very last question on the page.

@zander Hi Zander,
I wasn't able to get through the article as it seems to want to skirt the answer with there is no answer....maybe you can summarize it better?
-
What I got from the article is that the concept of R-value is not actually helpful. R-value is helpful if you are comparing different types of fiberglass insulation, because that is what R-value was designed to do. I think this video does a great job of demonstrating the insulative value of aircrete.
