Laminated glass is made by fusing two or more layers of glass with polyvinyl butyral ( PVB )as a bond. Its reinforced construction makes it nearly impossible to break into pieces. Instead, large cracks stay in its frame because it remains attached to the plastic layer in the center. It is commonly used for safety glazing. Glazing, or safety glazing, refers to glass that has been processed to be less susceptible to breakage and more importantly to reduce the potential for serious injury when it comes to human contact. We apply laminates when the glass must withstand heavy weight or pressure or if there is a possibility that glass could fall if shattered. Glass stairways and railings, automobile windshields , as well as walls, doors, canopy and skylights are some of the most common uses of laminated glass.
