Inadequate R-value in attics of older homes
Why it happens here
Many homes in the Main Street District were built before modern energy codes. They have only 2-4 inches of fiberglass, which is far below the recommended R-49 for Utah's climate.
Our approach
We blow in cellulose or install mineral wool to reach R-49 or higher. We also air-seal the attic floor to stop heat loss. This is the most cost-effective upgrade for these homes.
