My only problem with using sheets of foam is the labor involved. Lots
of caulking to make sure all those seams are sealed. The two component

installation).

Urethane foam give you better insulating value, but the costs/benefit
ratio is wacked for the joists due to the high cost of foam.




I'd use sheets of foam. Not far from the Boston area is Insulation
Technology in W. Bridgewater. They cut sheets from large billets and
can give you any size and thickness you want. Figure R-4 per inch
