A look at the state of the art today and the windows of the future. Since the publication of the first edition, research has yielded much new information on window technologies, their performance, and their benefits. This revised edition covers every aspect of window design and technology and includes a much-expanded section on energy performance, with an extended list of climate zones and glazing options. New tools and methods for making window purchasing decisions are also explained. Copyright (C) Muze Inc. 2005. For personal use only. All rights reserved.
