When you get a rock chip on your windshield in California, the clock starts ticking. Our sunny weather is beautiful for a drive along the coast, but it's the number one enemy of damaged auto glass.
Thermal Expansion and Glass Stress
Glass naturally expands when it gets hot and contracts when it cools. A perfectly intact windshield handles these tiny shifts without issue. However, a rock chip represents a weak point in the structural integrity of the glass. When the hot California sun beats down on your car, the glass heats up and expands, putting immense pressure on that weakened spot.
The A/C Shock Effect
The fastest way to destroy a chipped windshield is thermal shock. Imagine leaving your car parked in a hot lot in the valley, where interior temperatures can exceed 130 degrees. You get in, crank the air conditioning to max, and blast cold air directly onto the intensely hot glass. This rapid temperature change causes the inner layer of glass to shrink while the outer layer is still expanded, instantly tearing the chip into a massive crack across your line of sight.
Get it Fixed Fast
At Terrific Auto Glass, we see this scenario constantly. A repairable chip becomes an unrepairable crack in a single afternoon. If you catch it early, we can usually repair rock chips up to the size of a quarter, restoring strength to the glass before the heat ruins it.
