Windshields began as shields against wind, but they have evolved into much more than that. Besides protection against the elements and flying debris, they act to cushion the force of collisions. In addition to safety features, windshields today also offer cosmetic details.

History

    The first cars did not come with windshields as standard equipment, so motorists used goggles. Manufacturers sold plate glass windshields as luxury items. Still, they could shatter.

Growing Demand

    As people began to drive in all kinds of weather and bought more enclosed vehicles, the demand for windshields and windows increased. Laminated glass, which contained a cellulose layer, greatly strengthened windshields. Glass quality and production improved and costs dropped.

PVB Windshields

    Polyvinyl butyral replaced the cellulose inner layer of laminated glass, resulting in an even stronger windshield. PVB also absorbs shock during collisions and prevents passengers from going through the windshield.

Windshield Damage

    Most damage to modern windshields are chips from small rocks that tires throw into the air. The impact doesn't shatter the glass, but the crack weakens the glass and will spread if you don't repair the chip.

Additional Features

    Modern windshields offer many features, including heating elements, special sun coatings and antennae. You can also tint them in many shades.

Cost

    Windshield repair rather than replacement has grown in popularity. A new windshield costs between $250 and $1,000 but repairs average $50 to $75.
