We're building a new home in Macon, GA ourselves (completly ouselves) 2700-2800 sq ft with a metal roof and osb borad underneath it, and i going to insulate the exterior walls with closed cell spray foam. i was wondering if i should do the same in the attic and would it be worth the money to use closed cell in the attic and roof line vs open cell.  Should i use closed/open cell and do i spray the entire roof/attic?
