In 1909 Henry Ford offered his Model T with a windshield as an option. Nowadays, the windscreen does far more than protect the car occupants from the wind while on the move. Like so many other parts of the car, environmental, design, safety, security and comfort factors are driving automotive glass technology. The major glassmakers are working on rain-repellent glazing, plastic glazing and 'smart' sunroof glazing. Laminated side glass is also a growth area, both for security and safety reasons, while heated front windscreens are commonplace. But we can expect far more from tomorrow's windscreens.
