technician handling a windshield replacement at someone's house

Living in Las Vegas can take a toll on your windshield. What are differences between the mythology and the reality regarding the summer heat and windshields?

The Myth: Heat can shatter a windshield.

It’s not the heat, it’s a rapid change of temperature — rising or falling — that shatters glass. Rapid meaning seconds, not hours. Such conditions are rare anywhere on Earth, and, even in Nevada’s hot desert days and cold desert nights, the temperature changes slowly enough that you’ll probably never see this happen.

Some will say that heating air inside a car will create pressure that can crack your windshield, so leave the windows open an inch or so. Leaving windows open a bit won’t hurt, but cars aren’t airtight, and such internal pressure changes won’t change enough to cause damage, even if they were.

Cracks, however, compromise the structural integrity of your windshield and they can spread in extreme weather. Get that crack fixed at Clear Quality Auto Glass while it’s small and you may avoid a full windshield replacement.

The Reality: You can crack your windshield.

When you get into a car that’s been out in the hot sun, the air inside the car could be a lot hotter than the outside air — remember “the greenhouse effect” from high school science? Your natural tendency might be to blast the air conditioner and cool it down fast. Resist this temptation. A/C blast won’t crack your windshield, but the quicker you heat or cool glass, the more stress you put on it. Over time, this will put the glass at greater risk for chips or cracks, requiring a replacement sooner than you’d like.

In that same vein, don’t wash a hot car. Garden hose water is much colder than your car on a summer afternoon. If there’s a tiny flaw or chip or pit in a hot windshield, the cold water could cause that tiny flaw to expand fast and hard. Wash your car in the early morning or late evening, or after parking it in the shade for a while.

The Other Reality: Sooner or later, it’s gonna’ break.
