Modern windshields and windshield replacement (continued)
Let’s take a look at some of the things modern windshields do:
- Block road debris – since modern windshield glass is so tough, it offers us protection against a wide range of things we might hit while driving. Generally the only thing we have to worry about getting through a modern windshield is severe penetrating damage.
- Allow the airbags to work – This is one of the most critical functions of a windshield that many people don’t even know about. Airbags work by providing a cushion of air to push against the passenger and decelerate their motion, decreasing the chance of impact trauma against the inside of the car and keeping them better coupled to the car. To do this, they need something to push against – for every action there’s an equal and opposite reaction. In the case of many modern cars, the windshield provides the backstop for the airbag to push against. If the windshield doesn’t stay attached to the car throughout the wreck, the airbag can’t do its job.
- Hold the roof up in a rollover – Modern windshields are tough. Many modern vehicle designs rely on this fact to reinforce the structural integrity of their designs. If the car rolls onto its roof, the windshield is a critical part of making sure the roof doesn’t cave in and crush the occupants.
So, how do we make sure our windshield can handle what we need it to?
