After surviving a sweltering summer, many homeowners are looking for ways to control their thermostat, improve comfort and save money. One way to achieve all three goals is to replace existing home windows with more energy efficient models. The move will reduce energy costs and earn homeowners a federal tax credit. Plus, windows have a tremendous environmental and design impact and affect the light, ventilation and interior temperature of a home.
“Less efficient windows radiate more heat inside of a house,” says Chris Wood, operations manager at WeatherTite Windows in Buford, a replacement window company that specializes in the installation of custom built windows. “That causes the A/C to work on overdrive, sun damage to furniture and wastes energy. We build our windows to be more energy efficient and accommodate the conditions within a home.”
Before calling a window replacement company, homeowners should do their research and make some preliminary choices about the style of windows they”d like to put in their home. Wood says that homeowners should take special note of how the windows are made when making a selection.
“Homeowners should consider the construction of the window, including the frame, whether the window has double or triple pane glass, and the type of gas between the glass,” says Wood.
Key components of energy efficient windows include low-emissivity glass and the U-factor. Low-emissivity glass, or low-e glass, has a film covering on it to prevent solar rays from being transmitted through the glass into the home. Low-e technology keeps homes cool on a warm day by blocking heat, and on cooler days, prevents warm air from radiating out. Low-e windows can also include Argon gas between the windowpanes to provide even more insulation.
“Gas put inside windows during manufacturing absorbs radiant energy in windows and prevents it from entering the home,” explains Wood.
