Decided to go ahead and try to insulate the basement and crawl space. I'm just going with 2" bead foam over the walls. The void made up by the joist, sill and 1st floor, little to big to stuff with foam. Going to use blow - in. Also to many wires and pipes in the way. The Great -Stuff foam should hold the top in place. Planning to screw a 2"x4" into the concrete along the base to hold it. Which well work out since I plan to put insulated water barrel storage along the walls. Yep.
