Chips, bulls-eyes, stars, and half moons (continued)
There are two main considerations in deciding whether or not these chips can be repaired: size and depth. If the chip is too deep, or if the impact was so hard that it broke through the layers of the laminate, then the windshield will likely need to be replaced rather than repaired.
Likewise, if cracks have spread too far from the area of the chip in what’s known as a combination break (chips and cracks together) then the windshield will need replacing. Finally, if a chip contains road debris or dirt that cannot be removed by cleaning, or if it will obstruct the driver’s view, then the windshield must be replaced rather than repaired.
Floater cracks and edge cracks
A crack is damage without missing glass. If the crack is more than two inches from the edge of the windshield, it is a floater crack, and can be repaired as long as it’s not too large. An edge crack (one within two inches of the edge of the windshield) on the other hand will require windshield replacement since it compromises the structural integrity of the windshield.
A stress crack occurs without anything actually hitting the windshield. The most common cause of stress cracks is extreme temperature changes, and for this reason they’re not all that common in New Mexico. However, if you were to come out in the morning and see your windshield frozen over, and decided to throw a pot of boiling water on the windshield to melt the ice, you could very easily cause a stress crack. Stress cracks typically start at the edge of the windshield, and generally cannot be repaired. Windshield replacement will be necessary. Of course, Chapman Auto Glass offers mobile windshield replacement so you don’t have to interrupt your busy schedule to get that windshield repaired!

How does mobile windshield replacement work?
So, you were stuck driving behind a dump truck, and wouldn’t you know it, a tiny rock came flying your way and put a crack in your windshield. What comes next? Well, it depends. We’ve already discussed the crucial role your windshield plays in vehicle safety, so we know it needs fixing. But windshield repair and mobile windshield replacement gets complicated pretty quickly, and is governed by many laws and regulations. Let’s take a look at some of the basics pertaining to auto glass repair and mobile windshield replacement.
To repair or to replace?
A windshield repair can be a great way to save money over a replacement. However, given the critical importance of windshield strength, there are strict guidelines for when a windshield must be replaced rather than repaired. The general policy for windshield repairs used to be that if the damage can be covered by a dollar bill, then it could be repaired rather than replaced. However, in recent years, windshield repair technology has come a long way. Nowadays, it may be possible to repair a crack as long as fourteen inches, but it depends on a few other factors. The National Windshield Repair Association publishes a set of rules for windshield repair under the Repair of Laminated Automotive Glass Standard (ROLAGS) guide. To better understand what kind of windshield damage can be repaired, let’s go over a few different types of windshield damage.
Chips, bulls-eyes, stars, and half moons
When a rock hits your windshield and a piece of glass is missing, you’re dealing with a chip. Bulls eyes, stars, and half moons are all types of chips, named for what the chip looks like.

Types of auto glass (continued)
Non-tempered glass tends to shatter into long, needle-like shards. By breaking into so many small pieces, tempered glass is much safer for the vehicle’s occupants when it breaks. Car manufacturers also use single pane, tempered glass windows for the side and rear windows so that, should the vehicle’s occupants need to get out, for instance if the vehicle becomes submerged, they can break the windows and escape.
Windshields, on the other hand, are made of laminated glass. They typically contain two panes of tempered glass bonded to a central core, like a sandwich. This middle layer is made out of a material called polyvinyl butyrate, or PVB. PVB is extremely shatter resistant. So much so that an impact can shatter both layers of glass and the PVB layer will still keep the windshield in one piece and in the right place. That way, the windshield will stay in place even in a bad accident. This protects the passengers and keeps them in the car.
Windshields and passenger airbags
Windshield strength is also particularly important in vehicles with passenger airbags. This is because passenger airbags work by inflating and pushing against the vehicle’s windshield to create a cushion for the passenger. You might wonder, if laminated glass is so strong and durable, why not use it for all the vehicle’s windows? Well, if the side windows of your vehicle were made of laminated glass, it would make them essentially impossible to break out if you needed to escape through them. Nonetheless, some auto manufacturers have started to use laminated glass for the side windows of their cars. Why? Well, statistically, far more people are killed by being ejected from their cars than being trapped in them. Plus, laminated glass is much harder for a thief to break through.

The importance of auto glass
Your car’s windows do much more than keep the desert dust out of your face when you drive. Modern auto glass is technologically sophisticated and engineered to a high level of precision. It’s designed to reinforce the structural integrity of your vehicle, protecting passengers in the event of a crash and preventing them from being ejected. Because of the vital role auto glass plays, there are strict standards in place for how it is repaired and replaced. For example, did you know there’s a federal law that mandates drying time for adhesive used in a windshield replacement?
Let’s start by going over some auto glass basics:
Types of auto glass
The glass that makes up your car’s windows is typically very different from windshield glass. Your car’s side and rear windows are likely made of a single pane of tempered glass. When this type of glass shatters, it breaks into many very tiny pieces. This is quite different from the glass used in other applications, like the windows of your home for example.
