Potential Risks of Heat

Extreme heat can indeed pose a threat to your windshield. Here are some potential risks:

Thermal Stress

When your car is parked in direct sunlight, the windshield is exposed to intense heat. The temperature inside the vehicle can rise to dangerous levels, causing the glass to expand. As the glass expands, it puts pressure on the frame and surrounding components. Over time, this repeated expansion and contraction can weaken the glass and lead to cracks.

Existing Damage

If your windshield already has a chip or a small crack, the heat can exacerbate the problem. The intense heat can cause the damaged area to expand, resulting in a larger crack that may be irreparable. It is crucial to address any existing damage promptly to prevent further complications.

Prevention Tips

While you cannot control the weather, there are steps you can take to minimize the risk of your windshield cracking due to heat:

Parking in the Shade

Whenever possible, park your vehicle in the shade. This will help reduce the direct exposure to sunlight and lower the temperature inside the car. If shade is not available, consider using a sunshade or windshield visor to block some of the sun’s rays.

Crack Repair

If you notice a small chip or crack on your windshield, do not ignore it. Contact a professional auto glass repair service, such as OEM Auto Glass in Winton, NC, to assess the damage and determine if it can be repaired. Acting promptly can prevent further damage and save you from costly windshield replacement.

Temperature Control

When leaving your vehicle parked for an extended period, consider cracking the windows slightly to allow hot air to escape. Additionally, using the air conditioning or opening the windows for a few minutes before entering the car can help lower the temperature inside.
