Thanks

******************

Even 1 x 2 is OK since they are only holding the wallboard and not
structural. OTOH, I'd use 2 x 4 on the outside walls and insulated them.

You over estimated. It is about 0.25* as compared to wood at about .50.
Of course when you consider that it is DIRT CHEAP, that's not so bad. The
mud buildings in the American southwest use it because of both the price and
the insulation value when you have walls several feet thick.


* It varies a great deal depending on the soil mix and the amount of water
in it. It is also a good heat sink and will temper day-night changes very
nicely.

In cold climates with no insulation and dirt covering the basement
walls it is a drain on the utility bill, single pane glass is 1R,
imagine heating a glass house. I insulated my basement walls with 2
and 3" of R 7.2 foamboard, up to R 21, it helped dramaticly. Adobe
usage is in areas that even today dont have heating equipment. OP will
save alot by using more than 1" of foam. Logs homes are actualy fairly
well insulated, wood is near 1-1.2R. A 12" log might be 16R

I agree. Any additional insulation is good. Dirt varies from poor to
more poor. Of course even poor insulation added to whatever you have in an
improvement. Dirt has one additional function however. It is a great big
heat sink. If it is deep enough it moderates temperatures very nicely.
