laminated glass

…and relatively harmless fragments; and laminated glass, which consists of two layers of glass heat-welded together by an intermediate plastic film. Laminated glass can also be made with tinted lamination film, producing many colours not available in integrally coloured glass.

…absorbed by successive layers of glass and laminate, leaving less energy for crack development. Most glass products are laminated by bonding sheets of tough polymers such as polyvinyl butyral, polyurethane, ethylene terpolymer, and polytetrafluoroethane (sold under the trademark Teflon) to glass surfaces, generally by heat-shrinking. For windshield applications, paired sheets…

It may be constructed by laminating two sheets of ordinary glass together, with a thin interlayer of plastic, or it may be produced by strengthening glass sheets by heat treatment.
