Winter Wonderland for auto windshields

by Jason Jackson on February 4, 2017

Old Man Winter is here and he’s back at his nasty habits…cracking windshields. For fun, we like to image he’s a weathered and aged snowman (maybe Olaf, for those of you who are tired of watching a particular animated, wintry movie) who uses his ex-professional wrestling skills to crack windshields, instead of skulls, with his not-so-warm hugs (another Olaf joke, sigh). All jokes aside, winter is unfortunately the time when windshield cracks are most likely to expand. Keep reading to learn more about this frustrating, winter surprise.

It’s winter, and we all have tons of things to do and worry about. Next thing you know, the crack in your windshield – that you forgot to get repaired – is suddenly MUCH larger than the last time you saw it, and it’s right in your line of vision. Now you have two more things to worry about — your ability to see and drive safely and getting your windshield repaired or possibly, replaced.

So the question is, why do windshields crack in winter? First it’s important to understand that modern windshields are curved and contain two laminated layers that sandwich a layer of cellulose. According to a popular seismologist, windshields crack because, as the vehicle is exposed to extreme temperatures, the windshield glass expands and contracts at a different rate than the metal frame of the car. In winter, these different rates of expansion and contraction are especially stressful, particularly at the pointed ends of the crack. Eventually, this stress can result in further separation and a larger crack.

If you want to prevent your windshield from cracking in winter, be sure to have existing chips and cracks repaired by Jackson Mobile Auto Glass before the temperatures drop…and before Old Man Winter shows up! Also, let your car warm up before turning the windshield defroster on. This will help minimize temperature differences, especially on frigidly cold days.
