If you have been shopping for the right windows and doors for your home, you have heard of Low-E Glass and special glass with names that are unique to various manufacturers. The term "Low-E" stands for Low-emissivity Window Glazing or Glass that reduces energy loss as much as 30% to 50% and more.
The U.S. Department of Energy describes Low-E coating as a microscopically thin, virtually invisible, metal or metallic oxide layer deposited directly on the surface of one or more of the panes of glass. What are the advantages?
Low-E coatings reduce the infrared radiation from a warm pane of glass to a cooler pane. This lowers the U-factor There are different types of Low-E coatings that allow for high, moderate or low solar gain.
Another term you've heard of in relationship to a variety of products is Energy Star. This is a government-backed program that supports environmental protection. Windows and doors that qualify as energy efficient have certain requirements. These include two, three or more panes, Low-E glass to reflect infrared light and keep heat outside in the summer and inside in the winter.
Energy efficient glass also reflects damaging ultraviolet light. Some windows include gas fills between the panes such as argon, krypton or others that are odorless, colorless and non-toxic. These gases provide better insulation than air. Other features include spacers to keep the glass panes at appropriate distances from each other and improved frame materials and frame exteriors.
All of the name-brand window and door manufacturers featured at Dolan's are Energy Star qualified and new energy efficient options are also available.
