The first piece of glass found in most vehicles is the windshield, also known as windshields in European cars. This plays a key role in supporting the car's structure and protecting the driver and passengers. The rear glass, also called rear window glass, rear windshield, or rear glass, is the piece of glass opposite a vehicle's windshield. The back glass is made of tempered glass, also known as safety glass. When broken, it breaks into small round pieces, unlike a front windshield which is made of laminated glass, consisting of two pieces of glass with vinyl in the middle.
Auto glass can be either tempered or laminated. The glass generally used for the front and rear door windows and the rear window are made of tempered glass, while the windshield is made of laminated glass. Rear windshields are usually glued to the frame and cannot be moved, although some models have sliding planes or that can open upwards. When created, tempered glass for cars is treated with rapid heating and cooling processes. This causes it to break into small pieces that mimic the shape of pebbles when broken. These pieces are not sharp and do not cause bodily harm if they fall on a person's body. When there is a small crack or chip in the tempered glass due to something like a fallen rock, it cannot be repaired and must be replaced.
Tempered glass is also used in other industries to create products such as sunglasses, mobile phone screens, and saucepans or baking dishes. Laminated glass is used for windshields. Although it can break, this type of glass is designed to survive extreme impacts without breaking. This helps stop injuries that can result from flying shards of glass or from passengers being thrown through the windshield. Laminated glass was invented in the 1920s and is created when two sheets of glass are joined by a layer of polyvinyl butyral between them. After the layers are fused with high amounts of heat, the laminating process is completed. Outside of the automotive industry, laminated glass is popular in storefront windows, where it can break during a burglary. Auto glass repair is a permanent process that removes air from breakage and fills it with an optically blended, curable resin.
This area is used as a standard for the driver's critical vision area in most automotive glass shops and insurance companies in North America. Windshield repair involves repairing a break in a windshield or other piece of laminated glass in the car, rather than replacing it. The second type of aftermarket automotive glass comes from the OEM but was created on a different production line. In an automotive glass replacement context, it is usually made from high-strength polyurethane material unless specified. Although laminated glass is widely used in the automotive industry, it can be used for any application where there is potential for impact by a person. Mobile units are vehicles such as vans or light trucks that are properly equipped with repair, replacement, and safety equipment and tools which are driven to the home or workplace of an automotive glass repair customer.
