    This paper discusses the design considerations necessary for high performance glazing systems. Such areas as joint design and joint sealing, proper cushioning of glass, dissipation of heat, and control of air and water movement are examined. Performance characteristics of the various sealants and preextruded glazing tapes are cited, with values provided. In addition, cost and life expectancies are given. Special attention is focused on the problems associated with glazing high performance glass as well as safety glass. Movement, proper shimming, proper centering of glass, glass breakage, sealant compatibility, rabbet dimensions, and sash design are discussed thoroughly. A portion of the article is devoted to various aspects of a static and dynamic testing of glazing systems. The article concludes with a discussion of good glazing practices.
