Why Do Car Windows Break When It Gets Really Hot?
The direct sunlight can result in stress on the metal edges of your windshield, potentially causing it to crack.
Cracks on windshields often appear initially around the edges, as temperature fluctuations can cause the glass to expand and contract, making it more susceptible to cracking and facilitating the spread of existing cracks.
Can extreme heat cause car windows to shatter?
Exposure to extreme temperatures can cause glass to expand and contract, potentially leading to a decrease in its strength and the risk of the rear window shattering. According to Dan Hovey of Turnpike Motors Autobody in Newington, leaving a parked car in the sun with the windows up can create a greenhouse effect, causing the inside of the car to heat up significantly.
This can result in the windshield or back glass blowing out, posing a safety hazard. Therefore, it is important to take precautions and avoid leaving your car in hot sunlight for extended periods with the windows up.

Why does my windshield break in the summer?
The glass on your car is more susceptible to breaking when it cools down too rapidly after being hot. Temperature changes cause the glass to expand and contract, which can put stress on it and make it more fragile. Additionally, since people tend to travel and use their cars more in the summer, there is a higher chance of windshields becoming damaged.
Why do windows break in cold weather?
Exposing the window to cold temperatures can result in additional stress that may cause it to crack. This type of crack typically starts at the outer edge and extends towards the center of the glass. It is crucial to promptly replace any damaged windows because they can break in extremely cold weather.
Summertime Thermodynamics: Car Windows Open or Closed?
Cracking a car window can impact the overall temperature inside the vehicle. The glass windows create a greenhouse effect, causing the air within the car to become warmer than the outside air. By partially opening the windows, some of the heated air can escape while cooler air from outside enters the car. This leads to a lower equilibrium temperature compared to leaving the windows completely closed.
The process of cracking a car window allows for improved airflow and the release of trapped heat, reducing the potential for excessive heat buildup inside the vehicle. This can be beneficial during hot weather conditions, as it helps to maintain a more comfortable temperature within the car.
Are there any precautions drivers can take to prevent car window breakage in hot weather?
To prevent damage to your car, it is advisable to allow the air conditioner to cool down gradually instead of blasting it at full power. This will help avoid potential cracks in your windshield. Taking a few minutes for the car to adjust to the outside temperature can also be beneficial. Additionally, aiming the vents downward will prevent direct airflow from blowing on your windshield.
