Homeowners :: Home Insulation

Along with air sealing, your contractor may recommend that you add insulation to improve home energy efficiency. Many older homes are not well-insulated, and some have no insulation at all. Even new homes frequently have improperly installed or missing insulation.

Properly installed insulation in walls, floors, and attics provides for more even temperatures throughout the house and results in a quieter, more comfortable living environment that is easier to heat and cool.

For this region, the U.S. Department of Energy recommends:

  • Attic insulation: R49; approximately 12–17 inches, depending upon type
  • Wall insulation: R18
  • Basement/crawlspace wall insulation: R11
