With regard to windows, the primary consideration is energy loss. In a new house, for example, windows typically account for 15% to 30% of the total heating load and often over half of the summertime cooling load.

The 1.2 billion residential windows in the United States account for 3.2% of our national energy consumption and 9% of residential energy consumption, according to researchers at the Lawrence Berkeley Laboratory.

Vinyl is the preferred construction material due to its insulating properties and air chambers that provide a formidable barrier to heat transfer. Tests performed to the National Fenestration Rating Council (NFRC) method demonstrate the superiority of vinyl windows versus alternative framing materials.

Additionally, insulated glass with low-E coating and argon gas maximizes energy performance and minimizes sound transmission. Low-E panes block up to 75% of ultraviolet rays that can fade carpets, draperies and artwork. Argon gas, meanwhile, is six times denser than air, greatly improving thermal efficiency.

Reducing an electric bill is not only good for a homeowner, but for the environment as well. Whether your interior climate is at odds with the freezing temperatures of winter or the stifling heat of the summer, low-E (low-emissivity) argon windows can significantly reduce the amount of electricity used in your home.

Function Low-E argon windows are designed to minimize the effects of the outside climate on the interior temperature. When they are used, the interior climate of a home can be maintained longer before the heater or air conditioning must kick in to readjust the temperature. This is partly achieved through a double- or triple-pane design. Unlike traditional, single-pane windows, multi-paned windows provide additional protection against air leakage.

Benefits Between each pane of glass, low-E argon windows contain argon gas. Argon gas is considerably more effective at reflecting heat than regular air. This means that unwanted heat is deterred from entering the home and interior heat is prevented from leaving. Whether in spring, summer, fall or winter, the result is a more stable climate within the home.

Considerations The glass in low-E argon windows also features a special glazing that further reduces heat loss. This low-E glazing is often referred to as a pyrolitic, and features unique properties that allow visible light to penetrate into your home while blocking UV light and infrared (IR) light.

Types Low-E argon windows can be tailored to deliver either a high or low solar gain. High-solar-gain windows are ideal for homes that are situated in cold climates. Low-solar-gain windows provide superior results in hot climates.

Expert Insight The technologies involved in low-E argon windows result in a steeper price tag than that carried by traditional, single-pane windows. However, the extent of the savings on the homeowner's electric bill often results in net savings in the long run. If you plan on staying in your home for several years, the initial investment in low-E argon windows may be well worth the extra money.
