Architectural Laminated Glass consists of two or more panes of glass bonded together by a tough, durable plastic Polyvinyl Butyral (PVB) interlayer(s). When broken by impact, laminated architectural glass tends to remain integral in its frame, minimizing the risk of injury from sharp edges and flying or falling glass particles, and strongly resists penetration by the impacting object or person.
Building codes require the use of safety glasss in certain locations where people could be harmed if the glass were to break. These locations include door panels and saidelight, any window which comes within 18" of the floor,shower stalls, permanently mounted room dividers, and restaurant booth dividers, to name just a few. Regulations of this type were initiated in the early 1970s,when sliding glass doors had become popular in homes. Occasionally people walked into these doors and brok the glass, with serious consequences.
