What type of glass contains a thin film of plastic sandwiched between two panes?

Laminated glass is constructed by layering a thin film of plastic, typically polyvinyl butyral (PVB), between two panes of glass. This design enhances the glass's strength and safety, as well as its resistance to shattering. In the event of breakage, the plastic interlayer holds the glass fragments together, reducing the risk of injury and improving the resilience of the structure against impact. Laminated glass is commonly used in applications where safety and sound insulation are important, such as in car windshields and large windows in commercial buildings. This unique construction contributes to its performance characteristics, distinguishing it from other types of glass like tempered or double-glazed glass, which do not feature this plastic interlayer.
