An attic insulation calculator determines the thickness and R-value of insulation needed to meet energy code requirements for a specific climate zone. The US Department of Energy recommends R-38 to R-60 for attics in most climates. A 1,000 sq ft attic needing R-49 requires about 17 inches of blown fiberglass.
