All About Home Insulation And Caulking

A drafty house and high utility bills are signs that your home could benefit from some insulation and caulking upgrades.  According to the U.S. Department of Energy, heating and cooling account for more than half of the average home's utility costs.

Tighten Up and Save

Proper insulation creates a more comfortable home by not allowing air to seep in or out, and well-insulated houses stay warm during winter and cool during summer.

Here are several considerations:

  1. Existing conditions:  Determine the effectiveness of existing insulation and where insulation is missing.  Professional home energy auditors can pinpoint spots where energy is being lost.

       Locate auditors

  1. Insulation types:  Learn about insulation types, includingfiberglasscelluloserigid foam board, and spray foam.
  2. Performance measures: Understand R-value (the insulation performance measure) and what is appropriate for your location and climate

Eliminate Drafts

Sealing and weatherstripping projects are perfect complements to insulation upgrades, and some projects can eliminate drafts.
