2. They Manage Heat and Pressure
The dots also help the glass handle extreme temperature changes.
They create a gradient between the solid black border and the clear glass.
This soft transition prevents the glass from warping or cracking when exposed to sunlight.
3. They Improve Aesthetics
The dotted pattern helps the border look smoother and less “blocky.”
It also hides dirt and adhesive from being too visible around the edges.
4. They Help in Manufacturing
During the glass bending process, the ceramic dots absorb heat at different levels.
This allows the glass to bend evenly and fit perfectly into the car frame.
Final Thoughts
So, those dots aren’t just decoration—they’re a clever piece of engineering. They protect your car, keep the glass stable, and even make the windows look better.
👉 Next time you’re in a car, take a look—you’ll know they’re there for a reason most people never realize.
