Laminated glass is a multifunctional glazing material that is manufactured by permanently bonding two or more pieces of glass with layers of Polyvinyl Butyral. (PVB) interlayer, under heat and pressure, to create a single construction. It not only has a good optical nature, but also resistant to penetration, ultraviolet etc, it is widely used in areas such as defense, industry, transportation construction etc.
