Abstract

Laminated glass has been in use since the early twentieth century, beginning with automotive applications and expanding to applications in locations where strong, durable, transparent panels were required and hazards to life and injury were critical. Poly(vinyl butyral) (PVB), with suitable additives and plasticizers, has enjoyed the bulk of the market for interlayer material for use with glass. Relatively recently, other materials such as polyurethanes, acrylics, and polycarbonates have found applications as interlayer materials because of their respective properties. Types of applications, properties, and construction details of various laminates are presented, as well as fabrication techniques. Specifications are referenced that govern the use of laminated glass products in motor vehicles and in building construction. In addition to providing shatter resistance and improved security to conventional windows and viewing panels, laminated glass may also be used to provide unique colors, patterns, electromagnetic filtering/shielding, and electrical/electronic capabilities. Many of these applications are discussed in detail.
