Window technology has changed dramatically in the last 25 years, first with
the introduction of insulated glass, then with new frame materials such as
vinyl and clad wood, and again when high-tech coatings began to make windows
even more energy efficient. Residential Windows: A Guide to New Technologies and
Energy Performance ($22 from W.W. Norton & Co., Inc., 500 Fifth Ave., New York,
NY 10110; 800/233-4830; www.wwnorton.com) can help
both builders and their customers make informed choices
when trying to find the right window for the job.
Drawing on research done at the Lawrence Berkeley
National Laboratory, authors John Carmody, Stephen
Selkowitz, and Lisa Heschong pack six chapters and five
appendices
