[edit] Other polymers

Acrylic may be among the most durable materials with a lifetime of 20 years. (Clark, A. F., "Weatherability test of plastic glazing materials for collectors" in Sun II; Proceedings of the Silver Jubilee Congress, Atlanta, Ga., May 28-June 1, 1979. Volume 1. (A80-33401 13-44) Elmsford, N.Y., Pergamon Press, Inc., 1979, p. 401-404.[1]) It is more expensive than glass, but lighter and less breakable. It is not a high temperature polymer. This makes it more suitable for use as the outer layer of double glazing where it will block most of ultraviolet light that would otherwise degrade the inner layer. Polyester and fiberglass reinforced polyester may be good choices also.[2][3] Walter Siegmund 05:50, 11 February 2007 (UTC)
