yard shed insulation
I have a new 12x12x10 yard shed. I am going to insulate it, but wasn't sure what thickness of Foamboard I needed. Is 3/4", or 1" enough for the walls, and 2" good for the rafters? Is this too thick? I live in the Chicago area, and will work in the shed occassionally in the winter. No paint or chemicals will be stored in here though. THANKS!
