Laminated glass (also called sandwiched glass)  is manufactured by bonding two or more layers
Of glass together with layers of PVB, under heat  and pressure, to create a single sheet of glass.
When broken, the PVB interlayer keeps the layers  of glass bonded and prevents it from breaking
Apart. Windshields are typically laminated  glasses. The interlayer can also give the glass a higher
Sound insulation rating.
