Does Heat make Windshield Cracks Spread?

Can Heat Crack a Windshield?

Many car owners often find themselves wondering why and how cracks can suddenly extend across their car windshield out of nowhere. The damage is often just a hairline that seems to grow before your eyes. In other cases, an object hits your windshield, causing a small chip or crack. If you’ve ever wondered how these cracks can seemingly appear and spread so quickly, you’re not alone.

One possible explanation is that when exposed to extreme heat, glass expands and contracts, which can cause stress on the windshield and lead to cracking. The expansion and contraction can also cause any existing cracks to grow larger. This is especially true in extreme weather conditions, such as when it’s very hot or cold outside.

The Effect of Different Temperatures on Your Windshield Glass

Cracks in your windshield are caused by stress points. These can be from impacts, temperature changes, or even manufacturing defects. The heat causes the glass to expand and contract at different rates; over time, these stress points will cause the crack to spread. For example, if you park your car in the sun on a hot day, the heat can cause any existing cracks to grow larger. Similarly, if you’re driving and hit a cold patch of air, the sudden temperature change can also cause cracks to spread. So if your vehicle has a windshield crack, it’s best to get it fixed as soon as possible. Otherwise, the changing temperatures will cause it to spread, which can eventually cause the entire car windshield to shatter.

How to Prevent the Heat from Damaging Your Cracked Windshield?

Harsh temperatures are sometimes hard to avoid, especially in an area with extreme weather conditions. However, you can do a few things to help prevent the heat from damaging your windshield. The following are a few tips to help you protect your auto glass in extreme temperatures.


Park in the shade.

In hot weather, it’s best to park in the shade or in a garage. This will help protect your windshield from direct sunlight and heat. If parking in the shade isn’t possible, using a sunshade can also help keep the temperature of the interior of your car cooler. This provides a little assistance in protecting your windshield, but parking in the shade will always be best.

Avoid driving in extreme weather conditions.

Try to avoid driving in extreme weather conditions. If you must drive in these conditions, be extra cautious and take it slow. If you’re driving in scorching weather, keep your windows up and the air conditioner on to help keep the temperature inside the car consistent. Also, make sure to defrost your windshield thoroughly before driving if traveling in cold weather.

Don’t pour hot water on your car’s windshield.

If your windshield is iced over, resist the urge to pour warm water on it to melt the ice. The sudden temperature change can cause the glass to crack. Instead, use a scraper or brush to remove the ice. If you must use hot water, pour it slowly onto a cloth and then apply the cloth to the windshield.

If you have a crack in your windshield, get it fixed as soon as possible.

If you already have a cracked windshield, it’s best to fix it as soon as possible. This will help prevent the crack from spreading. If the damage does spread, you’ll need to replace your entire windshield, which can be expensive, unlike chips and cracks. There are many ways to fix a cracked windshield, so be sure to consult with a professional to find the best option for you.


What to do if Your Windshield Cracks Spread

Sometimes you can’t avoid a crack in your car’s windshield, no matter how careful you are. If this happens, it’s crucial to take action immediately to prevent the damage from spreading. If you have a crack in your windshield, don’t wait to get it fixed. The longer you wait, the more likely it is to spread and cause further damage. Be sure to take action immediately to prevent the problem from worsening.
