Different Ways How Hot Temperature Damages Your Car Windshield

Is prolonged exposure to hot temperature a serious problem when it comes to a car’s windshield? Yes! While the warm temperature may not directly crack your windshield, it is likely to be the underlying cause that weakens the entire structure. It can also cause a pre-existent hairline crack to spread. Therefore, before it gets to the point where you need to replace your car’s windshield, understand why sweltering temperature is never good news for automotive glass.

Why does Hot Temperature Matter?

Modern vehicular windscreens are built to withstand harsh weather conditions, like torrential downpours, snow, hail, high winds, and temperatures. However, even the most well-manufactured automotive glass is vulnerable to dings, cracks, and chips in extreme weather conditions. While you may think that a potential pebble or rock hitting your windscreen may be a more significant threat, it is indeed the temperature difference between the inside and outside of the windshield that can put your windows to higher risk or damage. Why?

Windshields expand in hot temperatures and contract in colder temperatures, but it often happens that the temperature alters suddenly, and this accelerated process can lead to cracking. As mentioned earlier, extreme temperatures can also lead to pre-existing cracks to spread much more aggressively.

The effects of hot temperature on a windshield can be better explained with the following example - Imagine you leave your car in direct sunlight, as often happens due to a shortage of parking. Doing this will allow your windshield to absorb some of the solar heat. Now you come back to your car and before driving, turn on the air-conditioner to full blast. By doing so, you will cause a dramatic change in the temperature inside the vehicle as opposed to the outside. This sudden change can pose a threat to the internal safety layer of your windshield, which is made of PVB or Poly Vinyl Butyral.

Another essential fact to keep in mind is that the opposite of what we have discussed also holds true during winters. You might end up needing to replace the windshield if it has received prolonged exposure to freezing temperatures. When you get into your car and turn on the heater to warm the interiors, it can wreak havoc on your windscreen. All of this is especially bad if you already have a minute chip or crack on your auto glass.

However, it is essential to note here that it is not possible to repair crack in windshield since even a slight crack has the potential to compromise the structural integrity of your vehicle significantly. Hence, in the case of cracks, the windshield must be replaced.

Tips to Prevent Windshield Damage

If due to some unforeseen circumstance your windshield gets damaged, you need to roll it into an expert service centre. However, there are a few good practices you can develop to improve the longevity of an automotive windshield and windows significantly.

Prevent Sudden Temperature Changes – Of course, you cannot control the weather on any particular day, but you can control the toggle switch on your AC and heater. Turn on the heating and cooling devices in your car gradually to allow the windscreen to adjust to the changing temperature.

Don’t Slam Shut Your Doors – You may not realize it or see any damage instantly, but slamming your car doors shut repeatedly can encourage cracks and chips on the windows of your vehicle.

Find a Shady Space to Park – It may take additional effort, but try finding a shady parking space for your car, especially during those scorching summer months. Doing this will keep the temperature inside your vehicle low.

Repair Chips Immediately – Do not wait for long to get even minor chips repaired. If left unfixed, they tend to grow into long fissures or multiple cracks waiting to shatter the entire windshield. It is also essential to bear in mind that fixing automotive glass, be it the windshield or windows is a fairly technical task – one that requires a true professional’s intervention.

Therefore, do not try to fix or repair said cracks on your own. Not only can a DIY solution lead to further cracks, but it can also end up costing you more if your windshield gets even more damaged in the process. Ask your friends or family members, and check out reviews online to select a reputed windshield expert.
