LOW-E WINDOW GLASS SAVES MONEY, ADDS COMFORT
LOW-E WINDOW GLASS SAVES MONEY, ADDS COMFORT TOLEDO, Ohio, Jan. 21 /PRNewswire/ -- "Lots of natural light,"
"open, airy rooms," "great views" -- that's the stuff homeowners' dreams are made of today.
As a result, windows -- whether new or replacement -- have become more important than ever as a key element in residential design, contributing greatly to a home's overall look and livability. Up to now, large expanses of glass were possible only by sacrificing energy efficiency. But with recent improvements in window construction, home buyers and home remodelers can now enjoy stunning expanses of glass and superb thermal performance. Although frames have received the lion's share of attention in terms of window improvements, the choice of glass used is actually of primary importance, since glass accounts for a full 85 percent of the window itself. In fact, glass is more important than ever in the purchasing decision, since fast-moving technology in the glazing industry has resulted in a host of high performance products. The single most significant advancement that has been adopted by the window and door industry is low-E (low-emissivity) glass -- specially coated insulated glass that keeps heat in during the winter and out during the summer, increasing the year-round efficiency of windows dramatically. "Emissivity" refers to the heat-emitting (or radiating) ability of a surface. The purpose of a low-E coating on a window pane is to keep the long wave infrared energy inside a room from passing out through the glass. Much of the incoming solar energy, however, can still pass through the glass as can visible light. As these rays are absorbed by flooring, furniture and walls, they are re-radiated as heat that is reflected by the low-E coating back into the home, resulting in a decrease in heating fuel and costs. Although low-E has been available as an option to standard glazings for a decade, several factors -- including rising utility bills, home designs with large expanses of glass and the heightened environmental consciousness -- have heightened interest in low-E glass products. One glass manufacturer has responded with a low-E product that combines heat loss prevention and solar heat gain for a 25 percent net energy gain over other low-E glass. Its product contributes up to two-and-one-half times more energy, measured in Btu's, during the day than is lost through them over a 24-hour period. "Windows made with Energy Advantage(TM) Low-E Glass become sources of free energy, not energy siphons," said Frank Mitro of Libbey-Owens- Ford Co. "This is the glass that keeps on giving -- saving money, adding comfort and increasing a home's value." Mitro explains that the same coating that provides significant savings during the winter months can also reduce summer radiant heat into a home by 36 percent, again increasing comfort level and decreasing cooling costs. Besides its energy-saving performance, LOF's low-E glass makes a home more comfortable by reducing cold, drafty areas around windows, reducing roomside condensation on glass, even reducing ultraviolet rays that fade furnishings. The glassmaker's claims are supported by Department of Energy tests that show that each window installed using Energy Advantage Low-E Glass in place of conventional double glazing in both new and existing buildings makes about 250 gallons of oil available for other uses over the life of the window. This provides enough gas to fuel your car for a trip across the country and back, about 6,000 miles. D.O.E. officials said that widespread utilization of low-E glass will have a major impact on national energy conservation and our dependence on oil imports.
