Seal Your Electrical Outlets to Improve Your Home Comfort

electrical outletsIn every house I visit to do an energy audit, the electrical outlets have been a major source of air infiltration. Sealing these holes up in your thermal envelope will reduce your energy usage and make your home more comfortable.
