Replacing old windows with ENERGY STAR certified windows lowers household energy bills by an average of 12 percent nationwide.
Are you tired of cold drafts and overheated spaces in the winter? Do some of your rooms feel like a sauna in the summer? A standard double-pane window allows approximately 75 percent of the sun’s heat into your home. Most ENERGY STAR certified windows reduce the “heat gain” into your home more than typical windows do, without reducing the visible light. You get the light you need without the uncomfortable heat. ENERGY STAR certified windows and doors keep your home’s temperature consistently comfortable.
Low-emissivity coatings on many ENERGY STAR certified windows and doors reduces UV sun damage to floors, carpets, and furniture.
