Laminated safety glass is best described as which structure?

• A. A single sheet of tempered glass
• B. Two sheets of glass bonded to a plastic interlayer between them
• C. Three sheets of glass with air gaps
• D. Plastic laminated on the exterior

Answer: (B)

Laminated safety glass is a sandwich: two sheets of glass bonded to a plastic interlayer between them. The interlayer holds the glass together if it’s broken, preventing shards from flying and helping maintain a barrier to penetration. This structure is what distinguishes laminated glass from tempered glass (a single, heat-treated pane that shatters into small pieces) and from insulated glazing with air gaps (three panes with spaces, not two panes bonded by a plastic layer). The defining feature is the plastic interlayer between two glass layers, which is what provides the safety and integrity characteristics of laminated glass.
