Frequently Asked Questions

Auto Glass Safety

We all know that the windshield and other auto glass in our vehicles keep out wind, rain and other annoyances while driving, but did you know that it actually has specific design elements that help keep you and your passengers safe?

It's true. Each auto manufacturer shapes and curves the windshield in specific ways that help ensure proper airbag deployment, and even keeps the roof from caving in if a roll-over accident occurs.


Selecting the Right Shop

Even when using your insurance for your new auto glass, you still have the right to choose which shop does the replacement or repair. When selecting a shop, be sure you're choosing one that implements the best practices set up by the Auto Glass Safety Council (AGSC). This will ensure that the correct glass, correct urethane, and proper installation techniques will be employed during the installation of the new windshield or other auto glass.


The Importance of Windshields


Advanced Driver-Assistance Systems

Driving technology has grown leaps and bounds in the past decade. Front-facing cameras mounted on or near your windshield have become a common safety feature on modern cars and trucks. These cameras are part of your vehicle's Advanced Driver-Assistance System (ADAS) and are designed to protect you and your vehicle on the road.

After a damage windshield is replaced, automakers specify that these systems must be recalibrated to ensure that the safety features continue to work as intended. At Capital Auto Glass we typically can complete windshield replacement and ADAS calibration at the same time.


Types of Calibration

  • Dynamic Calibration – This type of calibration requires driving the vehicle at a set speed on well-marked roads to recalibrate the camera system. This process can take up to 30 minutes to one hour after windshield installation.
  • Static Calibration – A specific target is required, usually an image mounted on a fixture in front of the vehicle during the recalibration process. Most static calibration tests take about one hour, but can take up to three hours.

We can perform most Dynamic and Static system calibrations at our shop. These systems protect drivers through a range of capabilities, creating a circular safety net around the vehicle to help reduce the risk of collisions. The front-facing cameras enable these advanced safety systems to aid and warn drivers on the road. Some examples include traffic sign recognition, lane departure warning, lane keep assist, lane centering, automatic emergency braking, pedestrian detection, collision avoidance, and more. If so equipped, the camera’s proper operation is a critical component of your vehicle's advanced safety system. The only way to make sure that the camera is aimed properly after a windshield replacement is to make sure the calibration is completed after a windshield replacement. There are no warning signs or indicators if the vehicle thinks nothing has changed. Unfortunately, this must be performed at our location and is not available for mobile service at this time.

OEM Glass

OEM vs Aftermarket Auto Glass

Why do we recommend OEM and OEE-quality glass? The answer is clear: OEM (Original Equipment Manufacturer) and OEE (Original Equipment Equivalent) glass is a better fit on almost all vehicles because it's up to the same specifications as the glass the manufacturers used when designing the automobile.

Most aftermarket glass has the same "block size" (the square dimensions of the piece of glass); however, with slightly different curvatures, contours, and other imperfections, the glass tends not to fit exactly as it should. (See example to the right.)

Using sub-standard glass in auto glass replacements can increase the chances for leaks, wind noise, and other issues. To avoid these headaches, it's best to insist on OEM-quality glass from reputable manufacturers and insist on Capital Auto Glass. Contact us.


Are OEM Auto Glass Replacements Worth The Money?

You've heard some compelling truths about the advantages of using OEM-quality auto glass in your replacements, still some people are skeptical, and others, just cheap. Sure you can find cheaper auto glass replacements out there that will look pretty nice when it's installed, but why risk it? Another great reason to insist on OEM-quality auto glass is that when you use OEM-quality glass, you're guaranteeing that the safety mechanisms in the vehicle can rely on the same quality glass as when it was run through the rigorous tests the manufacturer put it through during development. Don't settle for less; insist on the best!
