New Thermal Window Technology Lessens Menace of Jack Frost

Say what you want about the joys of Jack Frost nipping at your nose, but when it comes to winter wonderlands, I like mine outdoors. Etching icy messages on the insides of my windows is not exactly cozy. Therefore, I'm thankful for technology that provides an efficient and effective barrier from inclement weather.

Traco, a division of Kawneer and window manufacturer since the early 1940s, recently partnered with the DOE's Office of Energy Efficiency and Renewable Energy to utilize funds from the American Recovery and Reinvestment Act of 2009 to develop new window technology. These OptiQ™ Ultra Thermal Windows can reduce energy loss by up to 40% compared to the efficient, commercially available double-pane low-emissivity windows that are already on the market.

Each year, windows account for an estimated 4 quadrillion British thermal units (Btu) of energy lost in U.S. buildings, totaling over $35 billion in heating and air conditioning costs. Future window systems like the OptiQ™ Ultra Thermal Windows will eventually outperform the best-insulated walls or roofs in terms of annual energy performance, peak demand reduction, and costs. This new innovation holds promise to boost both savings and comfort. Read the full story on DOE's Energy Blog.
