How Can Heat Be Damaging to a Windshield Crack?

Hot outside temperatures heat up your windshield. When glass is heated, it naturally expands. If you have a crack or chip on your windshield and the glass begins to expand, the flaw can grow. This means a small chip can quickly turn into a crack and a small crack can grow into a larger chip.

How Can I Prevent Heat From Damaging a Windshield Crack?

Having the crack or chip sealed with a resin or acrylic filler can help ensure that it doesn't crack further in warm weather. Unfortunately, not all cracks can be repaired. If yours gets too large, impedes on your line of vision in the car, or starts to branch out in other directions, your windshield may need to be replaced, rather than repaired. Having the chip of crack sealed as soon as possible after happening is the best way to ensure you don't need a windshield replacement instead of a repair.

Can Anything Else Cause the Crack to Grow?

Heat is not the only thing that can cause a windshield crack to grow. As you are driving, your windshield may vibrate. This is more common on rough roads, when you hit a pothole or as you drive over bumps in the road. The vibration caused by this can cause your chips and cracks to spread as well. This just reinforces the importance of getting a crack of chip filled quickly, so that it doesn't grow larger simply because you were driving.
