Description
Two sheets of glass with a thin layer of vinyl plastic adhered between. Laminated glass was invented in 1903 by the French chemist Édouard Bénédictus when he notcies a glass flask containing cellulose nitrate did not shatter into pieces when it broke. During World War I, laminated glass was used to strengthen the windshields of military vehicles as well as for the eyepieces in gas masks. After the war, Safety glass was adapted for use in automobile windshields and skylights. When broken, the glass fragments remain attached to the plastic rather than scattering. The interlayer is usually Polyvinyl butyral (PVB), ethylene-vinyl acetate (EVA) or thermoplastic Polyurethane (TPU). The polymer interlayer gives the glass a much higher sound insulation rating, due to the damping effect, and also blocks most of the incoming UV radiation (88-99.9%).
