If there is one part of your car that is likely to sustain damage, it is the auto glass. Auto glass, whether it is the front or rear windshield or your windows, is designed to take an impact without completely shattering. However, cracks, dings, and chips can impair your visibility. When you talk to an auto glass service for repairs, don't be surprised if they come up with some terminology that is a little unfamiliar. Here are a few of the common terms you could hear and their meanings so you can better understand the repair process.
Floater Crack - If the technician working on your car windshield or auto glass states that you have a floater crack in the glass, it means that there is a crack that has started in the middle of the glass or not around the edges. Floater cracks most often are caused by stress, so a floater crack can be started with a ding or sharp impact that leaves a small chip in the exterior glass. However, floater cracks can also be relative to things like improper installation. If stopped early in the process, these cracks can usually be mended in a way that they are no longer visible.
Half-Moon Damage - If the auto glass has sustained damage from a piece of flying debris and the damage curves out from the impact point in a semi-circle design that does not go completely around the point, it is often termed half-moon damage. In the event the damage circles completely around an impact point, it is typically called a bullseye effect. Either of these types of damage can mean you will need a full replacement of the piece of glass, because these damages tend to have multiple crack points that are harder to fill with polymers.
Twist Crack - Twist cracks are usually associated with an auto collision of some type, but especially with rollover crashes that damage the frame surrounding a piece of glass. These cracks can only occur if the frame around a piece of auto glass is twisted to an extent that the twisting causes the glass to bust. The glass is sealed into its frame so tightly that even slight changes in the frame can cause giant stress cracks across the whole expanse of a piece of glass. In these situations, the entire piece of glass usually has to be replaced.Share
