Flash and Batt vs. Foam at Rim Joists
I’m considering doing a Flash and Batt style insulation on the house I am renovating, or at a minimum, using spray foam to seal in the chunks of polyiso I’m using for insulation at the rim joists and top plate to help with airsealing the house.
The house is in Zone 5 with 2×6 stud walls, and 2 1/2″ polyiso on the outside of the sheathing.
What brands of foam and applicator are well suited to a DIY approach?
