How high off the ground do you install foam boards? I am assuming they don't touch the ground. Can you explain the ground vapor barrier, wall vapor barrier and foam board. Like which one comes first, then over lap etc. Thanks.
Late but I can answer: Foam board IS suitable for wet locations and moisture has no effect on it. There's no spray foam on the rim joist though. That 1-2 inch gap is a termite reveal.
Foam board would be much more effective on the exterior foundation walls. Your block walls would be insulated between the ground and the foundation.

I'm pretty sure an answer is coming any day now.
