Modern architectural designs often require glazing materials that provide enhanced levels of security and safety performance properties. These properties include: resistance to ballistics, blast, hurricane/cyclic wind pressures and physical attack. Applications may also require desirable properties such as sound reduction, fade resistance, and solar & thermal control. Laminated glazing materials consist of multiple plies of glass, interlayers, resins and/or plastic glazing materials (such as polycarbonate sheet or acrylic), which are often complex in nature. They are designed to provide specified levels of performance. Design professionals and building owners should be aware of the considerations contained within this document when selecting and specifying laminated glazing constructions. The original version of this document was approved and published in 2003.
