Science of Laminated Glass

DuPont has developed glass that can hold together even when the panes break—using tough, adhesive plastic interlayers that are laminated between layers of glass. This helps prevent injuries related to flying glass or exposed shards. In cars, laminated safety glass also helps reduce accident-related head trauma and occupant ejection. In buildings it helps deter break-ins, prevent storm damage, improve energy efficiency, and even protect people from bombs and blasts.

The strength and other properties of laminated glass can be tailored to meet specific needs. Softer interlayers can help reduce noise. Stiffer interlayers can help glass perform more like a structural composite material. Laminated glass also enables aesthetic and energy-saving features to accompany basic safety performance.
