Laminated glass

Description

Two sheets of glass with a thin layer of vinyl plastic adhered between. First patented in 1910, laminated glass was used during World War I to strengthened the windshields of military vehicles. 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). The PVB interlayer also gives the glass a much higher sound insulation rating, due to the damping effect, and also blocks most of the incoming UV radiation (88% in window glass and 97.4% in windscreen glass).
