Chip & Crack Repair
Chips and cracks are the two most common types of damage to a windshield although sometimes a combination break develops which has the characteristics of both types of damage. Chips appear when something hits the windshield. The weight, shape and velocity of the object determine the degree of damage; a bullet causes more damage than a piece of gravel. The different shapes of damaged areas have specific names in the industry and your technician will usually refer to them by the “official” name. If you familiarize yourself with these terms, it will help us understand your problem a little better when you call us about windshield chip repair in the Austin area. Insurance companies consider these events to be no-fault occurrences because in most circumstances the driver couldn’t avoid the impact.
Common Types Of Windshield Cracks And Chips
Windshield Star Break
A Star break is defined by the Repair of Laminated Automotive Glass Standard (ROLAGS) as damage that exhibits a series of legs that emanate from the break. This type of break has multiple legs extending from the impact point and is characterized by their “X” shape or star-like appearance. Windshield Star breaks can be repaired if the total diameter of the break (including legs) does not to exceed 3 inches.
Windshield Bullseye Break
A Bullseye is defined by the Repair of Laminated Automotive Glass Standard (ROLAGS) as damage that is marked by a separated cone in the outer layer of glass that results in a dark circle with an impact point. It is round with no cracks radiating from the center impact point. ROLAGS sets a maximum size for Bullseye break at one inch.
Windshield Half Moon Break
A Half Moon break is defined by the Repair of Laminated Automotive Glass Standard (ROLAGS) as a partial Bullseye that’s no larger than one inch. The Half Moon consists of a half circle partial cone of separated glass around the point of impact.
Windshield Combination Break
A Combination break is defined by the Repair of Laminated Automotive Glass Standard (ROLAGS) as damage with multiple characteristics, i.e., Star within a Bullseye, short or long crack(s) emanating from the damage. More severe, this type of break is a combination of a Bullseye and Star break. Combination breaks can be repaired if the diameter of body (excluding legs) does not exceed 2 inches.
Other Windshield Repair Terms And Definitions
Each type of chip is repaired in a similar fashion. The technician inspects, cleans, dries moisture out, injects with resin while protecting the area from UV and subjects the area to pressure and vacuum cycles. When the resin has spread and the vacuum removes all the air from the break, the technician applies pit resin and holds an ultraviolet light over the area for about five minutes to cure the resin. The tech then takes a razor blade to smooth the area and cleans and polishes the area.
Damage occurs when there’s a break in the laminated glass of a windshield. A windshield is more than a single layer of glass. It actually consists of two or more layers of strengthened glass that are bound together by a layer of plastic. This bonding keeps the glass in one piece following an accident. It’s very important to keep a windshield in good repair. Damage can interfere with the wiper motion, reduce visibility and lead to further spreading of the original impact area. The windshield is an important safety feature of the car and only certified technicians have completed approved training courses. Since we specialize in windshield chip repair in Austin, all of our technicians are certified and experienced. The owner of Auto Glass Rescue is a firefighter, and public safety is our primary concern.
A ding is another term for a chip, and dings come in all shapes and sizes. If the damage is too large, you must replace the entire windshield. We offer free consultations. Measure the affected area and email us the dimensions and photograph of the damaged area. Remember to include your phone number in the message. You don’t want to ignore damage because the average consumer doesn’t understand the potential for further harm that may arise from untreated defects in the glass. Weakness can spread like ripples in a pond. If the bond between the layers of glass is penetrated, the entire windshield needs to be replaced as soon as possible. In this case, repairs aren’t sufficient and the automobile is not safe to drive. All dings are not created equal. Let a certified technician evaluate the situation.
The impact point is the place on the windshield where the object hit the glass. Sometimes this will be a minor nick, but it can be a major point of weakness in the glass. If the point of impact is not too large, the technician can most likely repair the damage. The first thing that needs to be ascertained is whether the object penetrated to the plastic inner layer of the windshield. In order to do this properly it may be necessary to observe the damage from inside the car as well as from the outside. If the object pierced the middle layer, the windshield needs to be replaced and not repaired. If the damage is repairable, the technician cleans the area. All debris, dirt and glass have to be removed from the site. Otherwise, the resin cannot completely fill the area and the bond can’t adequately form. In that case, the windshield will have a permanent point of weakness and additional breaks are likely to occur around the site.
A pit is an impact point that has chipped away some glass. A pit is more difficult to clean because the tiny pieces of glass must be removed from the area. The technician may use a blower as the first step and then observe the area under a magnifying glass. If pieces remain in the cavity, he needs to retrieve them one at a time. If the pit diameter is larger than 3/8 inch, the Repair of Laminated Automotive Glass Standard (ROLAGS) recommends that the windshield be replaced rather than repaired. ROLAGS defines a pit as damage with a minimum diameter of 1/8 inch.
