Sealing and Insulating

Sealing and insulating the "envelope" or "shell" of your home — its outer walls, ceiling, windows, doors, and floors — is one of the most cost-effective ways to lower energy bills and improve comfort. To seal and insulate with ENERGY STAR:

  • Seal air leaks throughout the home to stop drafts
  • Add insulation to block heat loss in winter and heat gain in summer
  • Choose ENERGY STAR qualified windows when replacing old windows.

The links below will take you to training materials and other tools you can download and use as-is, or incorporate into your own training materials. This is a complimentary resource EPA provides to its partners. Each training piece will provide you with up-to-date savings numbers and key messaging to help you, your staff, and your vendors communicate effectively with consumers about the benefits of sealing and insulating with ENERGY STAR.
