4 Things That Can Cause Cracks In Your Windshield

It's a common misconception that windshields are made of glass. In reality, windshields are made from laminated layers of plastic and resin with a thin layer of safety glass in the middle. The windshield is designed to be flexible, so it can move when something hits it- this flexibility also makes them vulnerable to cracks if they aren't installed correctly or if there is an issue with the adhesive used during installation.

Here are four things that can cause windshield cracks:


If the windshield isn't correctly secured, it might come loose, triggering fractures from stress. It's very important that windshields are installed properly to avoid this issue.


Fluctuations in temperature, particularly if you use a defroster or the vehicle's heater, might cause the glass to expand and contract. Because the glass warms more rapidly around the edges, these expansions and contractions occur at diverse paces, resulting in cracking.


Sunlight has the same effect as temperature changes in terms of breaking glass. The metal near the edges is heated faster than the center of the windshield, causing fractures.


Small cracks can develop unexpectedly, and they may appear to emerge out of nowhere as a result of pressure changes, such as sudden strong wind gusts or even placing something hefty on the windshield.

In conclusion, windshields are constructed from flexible materials to allow them to absorb blows without shattering. Windshield fractures can still develop for a variety of reasons, including poor installation or temperature changes and pressure swings. The best way to avoid cracking is to prevent it.
