I have four 7ft x 1.5 ft bays in the basement ceiling that I want to insulate. I can see through the floor boards to the carpet insulation directly above.
Is it reasonable to use several cans of foam and spray up? I know the foam is sticky, but I wonder if too much of it will rain down making it impractical. I've worked with the foam before for small spaces.
Option 2 is to cut polystyrene board and then put bats under it. I know it can be a bear to cut it just right, though.
