I insulated the outside wall with 1" foam board. My thought is that my

really need a lot of insulation on common walls, even if they are
poured ?

If the temperature on both sides of the wall is the same, what's the purpose
of the insulation?

On the other hand, insulation may prove useful for noise abatement.

Another question:
Some of the DIY construction books show not studding out basement
walls but just screwing up 2x2s and attaching wall board to them. Is
this recommended or not ?
