There's no doubt that windows are getting better — much better. The double-glazed, low-eLow-emissivity coating. Very thin metallic coating on glass or plastic window glazing that permits most of the sun’s short-wave (light) radiation to enter, while blocking up to 90% of the long-wave (heat) radiation. Low-e coatings boost a window’s R-value and reduce its U-factor. units that looked so ground-breaking a few years ago seem merely ordinary now that Canadian, European and some U.S. manufacturers are producing high quality triple-glazed units.
Triple-glazed windows offer substantial benefits, including improved indoor comfort and lower energy bills.
But they aren't cheap. Homeowners who are already facing painfully high building costs have to weigh the costs against the benefits. Are triple-glazed windows really worth the added cost?
