I'm considering insulating the crawlspace under the house, under the new
wood flooring. I have good access to all areas under the new wood
flooring, and to all exterior walls. I can walk under the entire area.
The floor joists are 2 x 10 (1 3/4 x 9), and the wall studs are 2 x 4 (1
3/4 x 3 1/2). I've been reading a lot about insulating crawlspaces, and
some say just need to insulate between all the joists, and others say
best to insultate just betwee the studs. Of course, doing just the studs
would be much easier, since it's doesn't have to be 'hung', and less
expensive, since the insulation wouldn't have to be as thick.

Any suggestions?


You want to insulate both walls and floor. I'd use foam board with
adhesive to hold it on the floor above.
