How much will I save by upgrading my attic insulation to R50?
Savings are greatly dependant on how much insulation is in the attic to start with. Another item that helps save on energy is air sealing. Air leakage accounts for 40% of a home’s energy loss. Using self sealing products like spray foam help eliminate drafts and mass air exodus. Increasing an attic from R12 to R50 typically saves 20-25%. Air sealing with spray foam can help increase overall savings.
