I have a room stripped bare to the studs. Its a corner room on the first floor, so I'm planning on reinsulating the two exterior walls. I'm wondering if I should do anything with the areal where the ceiling/floor joists between the first and second floor reach the edge of the house. Basically there is a 2x6 block, 1/2" sheathing, foam and then vinal siding. Should I try to add some insulation in these end cavaties between the floors?
