Can a Windshield Shatter from Heat?

Have you noticed small cracks or chips in your windshield? If ignored, even minor damage can spread, ultimately requiring a full windshield replacement. While road debris and incorrect windshield installation can contribute to auto glass issues, one of the most significant threats to your windshield is temperature fluctuation.

Warm Weather Increases Stress on Windshields

As we shift from colder winter weather to the warmer months of spring and summer, minor windshield damage can escalate due to temperature shifts. When the cabin temperature of your car rises, the pressure on your windshield also increases, potentially worsening existing cracks.

How Heat Impacts Auto Glass

Your windshield is made of two glass layers with a protective vinyl layer sandwiched in between. Typically, small cracks or chips only affect the outer glass layer. However, increased temperature stress can cause these small imperfections to expand. Similarly, when you turn on the air conditioning, the cold air can create additional pressure on the windshield, especially when warm air is still hitting the glass from the outside.

Windshield Replacement and Repair Solutions

If you spot any cracks in your windshield, consider professional replacement as soon as possible. Taking care of it in the spring can prevent further damage caused by rising temperatures. If immediate replacement isn’t possible, here are some tips to minimize added stress on your windshield: 

● Avoid blasting the air conditioner immediately after entering your car. 
● Park in shaded spots whenever possible to keep your car cooler. 
● Close your car doors gently to avoid jolting the windshield. 
● Gradually adjust the cabin temperature instead of sudden increases or decreases. 
● If the chip or crack is smaller than six inches, professional repair may be an option, which can save you money.
