Windows are a major factor in the street appeal of a home. Appropriately styled windows add to the architectural style of a structure. Windows also allow light and air to enter the interior, contributing to a pleasant indoor environment. Single-pane or poorly installed windows are, however, a major source of energy loss. Windows and doors account for approximately 30 percent of the energy loss. Energy-efficient windows reduce transfer of heat through the glass and frame, resulting in lower electrical bills.
If you are building a new house, energy-efficient windows can be easily installed during construction. If you are considering replacing your windows, energy-efficient windows can be fitted to existing openings. The new windows can lower utility expenses by reducing thermal transfer of heat, including limiting solar gain in summer and increasing solar gain during cold months.
The effectiveness of a window to resist heat flow is called the U-value or U-factor. The lower the number, the better the insulating value. The type, number of layers and size of the glass, the tightness of the window installation and the insulating ability of the frame material affect resistance to heat flow. If your windows have single-pane glass, are not well sealed or are made of a material that easily transfers heat, replacement windows may save fuel and money.
Thermally effective materials for frames include wood, vinyl, fiberglass, aluminum and combinations of these materials. Vinyl is a popular choice of consumers; the energy efficiency of vinyl is moderate to high. Vinyl is easy to maintain, is available in many styles that complement a variety of architectural designs and is easily customized. Vinyl can be reinforced with steel or aluminum bars for large areas. Wood is a traditional window frame material with good thermal properties, but requires maintenance.
Double- or triple-glazed panes provide a barrier between thermal variations in inside and outside temperatures. Some windows contain inert gas such as argon between panes that reduces thermal exchange between outside and inside temperatures. Glass treated with low-emissivity coatings reduces heat transfer from the house to the exterior during cold months and prevents heat from entering during warm months.
Energy Star, an energy efficiency program under the U. S. Environmental Protection Agency, evaluates household building products and electronics for their ability to save energy. Products that carry the Energy Star label meet the stringent requirements of the program. Energy Star recommends a U-factor of .35 or less for windows in Pulaski County and nearby areas. Windows that carry the Energy Star label have been independently tested by the National Fenestration Rating Council for their energy efficiency values.

An energy Star label will contain several valued including the U-value and solar heat gain coefficient (SHGC). The solar heat gain coefficient is the amount of solar radiation that penetrates a window and is converted to heat. It will also display values for air leakage and how well the product resists condensation.
