Although a car’s windshield is designed to withstand the elements, it’s not invulnerable, especially if there’s already some damage. Even a tiny chip or hairline fracture can make a cracked windshield susceptible to all sorts of problems. Heat tends to be one of the worst offenders. For example, if you park it directly under the sun, especially during the warmer seasons, it can worsen the situation. Here’s a breakdown of why this occurs. 

Why Heat Is Bad for Cracked Windshields

Expansion & Contraction

The primary reason why cracked windshields can deteriorate under heat isn’t due to the high temperature. It has more to do with fluctuations in temperature. Even extreme cold can exacerbate problems. When things are cold, they contract; when they’re hot, they expand. The bigger the change in temperature, the more the object can change in size. If there are no cracks, these conditions will primarily affect the edges, but when cracks are present, the swelling and shrinking will be present along those lines as well. 

Added Stress

The external temperature isn’t the only factor impacting your windshield. Setting your air conditioner or heater too high can also contribute to the problem. Try not to change too much at once. Consider the outside temperature and calibrate your system accordingly. 

Prevention

Aside from slowly adjusting the temperature, park your car in the shade or indoors when possible. While the latter is preferred, look for a shady spot when you’re out, especially during summer. A little shade can make a significant difference.
