Well, I can tell you NOT to use batt's in the floor...total waste of $$ IMO. Even if you put them up with chicken wire so they can't fall, eventually they're going to get saturated with moisture and be worthless.
Plus it's more of a pain to install, and then if you need to repair plumbing/wiring it's got to come out. Dumb idea IMO.
While we're on the topic...I know codes vary by township, but most of MI should be similar (southern LP atleast). Code issues with removing crawlspace ventilation? Too lazy to look up right now...
