energy STAR Standards energy STAR qualified windows meet strict performance standards es-tablished under the energy STAR program by the Environmental Protection Agency. energy STAR qualified windows feature: yDouble or even triple panes of glass with inert gases such as argon between them that vastly improve the ability to insulate against unwanted heat flow into or out of the house, depending on the time of year. yWindow frame materials designed to improve the window s insulating abilities. ySpacers that keep a window s glass panes the correct distance apart to reduce heat flow and help prevent condensation. ySpecial coatings to create low emissivity ( low-E ) glass. Such low-E glass reflects heat energy either into or out of the house, further enhancing insula-tion. It also reflects ultraviolet (UV) light away from the house and can protect your household furnishings from UV-induced fading by as much as 75%.
