Caring for your windshield is challenging because many factors affect its quality. For example, cracks are more common in the summer because the extra heat can expand the glass. Below is more information about how heat damages your vehicle’s glass so that you can protect it.

How Heat Influences Windshields

Manufacturers temper the glass in your vehicle to prevent damage from rocks and other debris. While this doesn’t mean it can’t break, it is more difficult to crack. Additionally, the windshield is a few millimeters smaller than the frame to ensure it won’t break when the glass expands and contracts from the outside temperature.

When heat expands the glass, a windshield with an improper fit will experience extra stress, causing it to crack. Alternatively, it may have stress cracks if you turn on the air conditioner immediately after the car has been sitting in direct sunlight for long periods. The glass cannot withstand sudden, extreme temperature changes.

There are dangers to your windshield in winter, as well. One of the most common ways of removing ice on a car’s windows is to turn the defroster up. This is another abrupt change that stresses the glass. In vehicles with high-efficiency heaters, the sudden change can cause the glass to expand too quickly.

How to Protect Auto Glass 

The best way to prevent damages is to avoid sudden temperature changes. This means gradually adjusting the temperature on the air conditioner or heater.

You should also park your vehicle in shaded areas whenever possible, such as a parking garage. Even though the car will still heat up, it won’t get as hot as it would under direct sunlight. Also, watch for chips in the glass from pebbles and other debris. Leaving a chip allows the glass to crack further. Repair any damage to your windows as soon as possible to avoid more extensive repairs.
