Doors, Windows

With the thick of winter here, you may be experiencing leaking or drafty windows. Maybe it's time to replace those old single-pane windows. Or maybe the winter blahs have taken hold and you're ready for a new look. Replacing your windows can help you save on your energy bill, provide a stylish new look to your home, and can be a strong lure when it comes time to sell.

Remodeler Magazine says that changes in technology, including alterations designed to increase energy efficiency and convenience features such as tilt-out hardware, can make recently installed windows a prime selling point for prospective buyers.

The magazine's 2002 Cost vs.Value Report says an upscale window replacement project (replacing 10 existing 3-by-5-foot double-hung windows with double-glazed divided-light windows with interior finish of alder or cherry and exterior finish of copper or aluminum cladding) cost a national average of $15,502 installed and yielded a slightly higher return of 77 percent over replacement windows at a mid-range price point.

The mid-range job (replacing 10 existing 3-by-5-foot double-hung windows with vinyl-clad double-glazed replacement windows and not disturbing existing interior or exterior trim) had a national average cost of $9,424 and the cost was recouped at 74 percent.

But new windows do more than just look good. They're also a source of heat, and need to be tinted or shaded to reduce heat, but those options also reduce natural light. And not only do windows increase a room's temperature fluctuation, but incoming light can also cause fading of carpets, fabric, wallpaper, paint and wood.

By using energy efficient replacement windows, you can reduce light and heat transfer, as well as heating and cooling costs.

According to the U.S. Environmental Protection Agency's Energy Star Program U.S. Environmental Protection Agency's Energy Star program, which began in 1992 as a voluntary labeling program designed to identify and promote energy-efficient products, the average household spends more than 40 percent of its annual energy budget on heating and cooling costs. You can save 15 percent of that with Energy Star-qualified windows.

The Efficient Windows Collaborative, a group that manufactures and promotes energy-efficient windows and receives support from the U.S. Department of Energy's Windows and Glazings Program, says the most harmful sunlight rays are ultraviolet (UV), which are the most energetic and most likely to break chemical bonds, leading to fading and degradation of materials with which the light comes in contact.

The EPA says that windows with Energy Star labels are energy efficient all year long and are twice as efficient as the average window produced 10 years ago. They're available in aluminum, fiberglass, vinyl and wood, and include design styles such as single-hung, double-hung, casement, horizontal slider, fixed and picture, as well as patio slider.

All Energy Star windows are labeled by the National Fenestration Rating Council, a non-profit, public/private organization created by the window, door and skylight industry and comprised of manufacturers, suppliers, builders, architects and designers, specifiers, code officials, utilities and government agencies. The NFRC provides unbiased energy performance ratings on window, door and skylight products.
