The Energy Star window and door program is a voluntary partnership between the U.S. Dept. of Energy (DOE) and the window/door industry to educate consumers about energy efficient products with superior thermal performance ratings. The DOE and the Environmental Protection Agency (EPA) developed this program because most states do not have adequate codes regarding energy efficiency for these products.
Now consumers do not have to be confused or misled by manipulative sales methods in reference to ratings such as R-factors or U-factors. As an example, some companies “manufacture” high ratings by testing only certain components of their products such as the center of the glass rather than testing the entire window. Consumers can feel confident when they buy an Energy Star compliant product, that they are buying a window or door unit that meets a minimum standard of performance for the entire unit. Mr. Enclosure Sunrooms, LLC All Season Sunrooms are Energy Star compliant!
