How much do you know about the windows in your vehicle? Since those windows play critical roles in keeping you and your passengers safe on the road, it’s important to have an understanding of the basic facts, at the very least. What are those facts? Read on for the basics about automobile windows that every vehicle owner should know.  


Your Windshield and Rear Window are Special Types of Safety Glass

Your windshield and rear window are made from different types of glass. Here’s what you should know about each:


●        Windshield. Your windshield isn’t just one solid sheet of glass. Rather, it’s two sheets of glass with a sheet of polyvinyl butyral (PVB) in between, which makes it laminated glass. The interior layer of PBV prevents the windshield from shattering in the event of a collision.


●        Rear window. Your vehicle’s rear window is made of the same type of glass you use to protect your smartphone screen: tempered glass. During manufacturing, that glass is heated and then cooled rapidly to make it extra strong, but even though it’s tough, it can still shatter under duress. If it does shatter, it’s designed to break into very small pieces that are less likely to injure someone.


If you ever need a windshield replacement or rear window replacement, be prepared for a cost difference between the two since these windows are different types of glass. 


Vehicle Windows Contribute to Advanced Driving Safety System Operation

If you own a modern vehicle, chances are it features at least a few basic Advanced Driver Safety Systems (ADAS). Some of the most common of these features include:


●        Adaptive cruise control

●        Collision warnings

●        Lane departure warnings

●        Backup assist

●        Anti-lock braking


These features are controlled by various sensors and systems placed throughout your vehicle, and some of those sensors are embedded in your auto glass. If you ever need a windshield replacement or any other type of auto glass repair, those sensors will need to be recalibrated to ensure your ADAS feature function properly. That means you’ll need to take your vehicle to a shop that specializes in static and dynamic ADAS calibration for all your auto glass repair needs.


Those Black Dots on Your Windows Actually Have a Purpose

Ever wondered what those small black dots around the edges of your windshield are there for? Those dots are called either the frit or the trim and they were initially implemented to camouflage the area where the windshield bonds to the frame of the vehicle. They’re baked into the glass itself, and nowadays they serve more than just an aesthetic purpose.


On modern vehicles, the inner-facing side of the frit or trim helps the glass adhere securely to the vehicle’s frame. The outer-facing side of those black dots provides a shield from UV radiation, which helps protect your dash from deterioration.


Auto Glass Plays a Role in Your Vehicle’s Structural Integrity

Your windshield doesn’t just protect you from weather conditions and outdoor debris while you drive. That glass actually contributes to your vehicle’s ability to withstand a collision without being crushed. In fact, the average windshield comprises about 30% of a vehicle’s structural strength, so if yours isn’t completely intact, your safety could be at risk.


Even a small chip or crack in the glass can weaken its structural integrity, and consequently, negatively affect the structural integrity of your vehicle in the event of a crash. To stay safe, make sure you tend to any auto glass repairs you may need as promptly as possible.
