Glass in integral to the design of every vehicle. It has several functions, from being aesthetic and regal to protecting the passengers in case of accidents. Until 1929 windshields were a luxury. It was only in 1924 that the glass industry made the production of plate glass efficient enough to be used in the manufacture of cars that had become a part and parcel of the social fabric.

Auto glass is essential for safe driving, and is specially manufactured in keeping with norms outlined by the Federal Crash and Roll Over Standards. Safety glass, as auto glass is popularly known is of two kinds: Laminated and Tempered.

Laminated glass has been used for windshields in automobiles since 1927 and is manufactured by placing between two glass panes a sheet of clear plastic film, and sealing them using heat and pressure. The plastic film is what prevents the glass from shattering and causing injuries on impact. Laminated glass also blocks high frequency sound and ultraviolet radiation.

Tempered glass is strong and made by using heat and sudden cooling. When it breaks it does not shatter, but forms small pebble-like pieces that are not sharp. Normally used in the side and rear windows of automobiles, tempered glass lends great strength, as well as wind and impact resistance.

When replacing auto glass one must ensure the windshield is perfectly centered. The molding must be flat and securely fitted with no gaps. From the outside, the glass should appear to be one with the vehicle
