What R-value is best for attic insulation in Canada? Compare R-40 vs R-60, costs, savings, and rebates to improve your home’s efficiency.

To maximize a home’s energy efficiency in Canada, the recommended R-value for attic insulation is R-60 (approximately 16 to 20 inches thick). While the National Building Code of Canada (NBC) typically requires a minimum of R-40 to R-50, depending on climate zone, aiming for R-60 can reduce heating costs by up to 15% to 30%, especially if your current insulation is outdated. Blown-in cellulose is one of the most commonly used methods to achieve this level of thermal performance in cold climates.
