foam board thickness - 1' or 2' ?
Aside from the extra benefit of greater insulation from 2" vs. 1" foam board being applied to basement walls before framing, are there significantly greater moisture control benefits between the 2" thickness vs. 1" thickness?
Code is requiring we use kraft insulation in the framing,so insulation level is not an issue. Does the 1" foam board adequately control potential moisture issues or should I spend a little extra money and get the 2" thickness to maximize moisture control? Is 2" thickness harder to install?
Does this answer change if we use metal framing?
