How fast does a windshield crack spread? As we'll cover in this post, there are a lot of factors that affect the speed of crack spread after the initial damage is done. Regardless of how the crack started or how fast it's spreading, it's important to
seek prompt repair. Read on to learn more or contact Wrecktify Collision today for more information and
auto collision service.
Changes in Temperature
Sudden temperature changes can take their toll on glass, causing it to either contract or expand. When this happens, parts of the windshield may weaken and cracks and chips may form. These cracks begin as very minor, even unnoticeable to the naked eye, before spreading over days or weeks.
Debris Collision
One of the leading causes of windshield cracks is coming into contact with stones or other debris as you're driving.
Hail Damage
Severe weather is another common cause of windshield cracks. Falling hail stones can do more than just dent the body of your vehicle, but crack and chip windshields too.
Vibrations
Constant vibration can put the windshield under pressure and lead to cracking and chipping.
Collisions
An accident or collision can also cause damage to the windshield.
Factors that Affect Windshield Crack Spread
Now that we've gone over some of the leading causes of windshield cracks, let's take a look at some of the factors that affect how fast it spreads.
Size of Crack
Smaller cracks are less likely to spread than larger cracks. That's largely because smaller cracks don't often penetrate all layers of the windshield. Larger cracks do, which usually causes them to spread faster.
Location
If the windshield crack originates at the edge, it's more likely to spread. This is because it's put under more pressure by the windshield frame.
Moisture
Windshields are comprised of layers. If damage occurs and moisture gets between the layers, it can do more than just accelerate the spread, it can lead to a cloudy windshield that makes it difficult to see.
Rough Roads
Regularly driving on rough roads or terrain? This type of driving puts more pressure on the windshield, which may cause cracks to spread.
Temperature Changes
Just as temperature changes can cause cracks to form, they can also cause existing cracks to spread.
Vibrations
Vehicle vibrations place more pressure on the windshield and can accelerate crack spread.
Debris (Dirt & Dust)
Dirt buildup can impact the structural integrity of a windshield and accelerate crack spread.
The Importance of Prompt Repair
Driving with a cracked windshield is a safety hazard, so it's important to
seek repair if you notice a crack has formed and is beginning to spread. Not only can it impact your visibility while driving, but it's a sign of weakened glass that could shatter more easily and cause more harm in the event of an accident or collision.
