What is laminated glass?
A. Laminated glass consists of two or more panes of glass with a tough plastic interlayer made of polyvinyl butyral (PVB), bonded together under heat and pressure. Laminated glass is also used as an effective sound control product. Laminated glass is commonly used in airports, sound studios, schools and in houses near freeways to keep away unwanted noise from airplanes, heavy machinery and traffic.

Laminated glass provides strength and beauty, durability and clarity to meet a wide variety of design needs. Long lasting and versatile, it is the only glazing material that combines the durability and strength of glass with the toughness of plastic. Laminated glass is made by bonding two more layers of glass, using heat and pressure, with one or more interlayers of polyvinyl butyral resin (PVB). The result is a tough, adaptable glazing material that offers outstanding features to meet a wide variety of design challenges. Depending on design needs, laminate glass can be man made with sheets of annealed, and/or tempered glass. It is easy to work with and replace, and provides important structural performance features and benefits: Safety Laminated glass by California Glass Bending Corp. resists penetrations from impacts. When broken, the glass adheres to the resilient PVB interlayer, remaining relatively harmless, unlike ordinary glass which may create dangerous shards, or tempered glas
In 1903, Frech chemist Edouard Benedictus accidentally broke a bottle of cellulose acetate in his laboratory. As a result, he discovered that the cellulose, upon hardening, held the fragments of glass together. This subsequently led to the use of cellulose as a binding agent in the glass laminating process. A Saint-Gobain patent of the process followed in 1910. Further development by Dupont and Monsanto led to the use of laminated windscreens in cars after the Second World War. Vinyls have long since replaced the earlier use of celluloid, which tended to turn brown with age and become brittle. PolyVinyl Butyral (PVB) is now the most common interlayer material used around the world for laminating purposes. Other forms of Laminating glass are found here.
