Auto glass
Windshield, side and rear glass for passenger vehicles. Vehicle identity and fitted equipment are confirmed before pricing.
Which glass, exactly
Every vehicle has several separate pieces of glass. Tap the damaged glass on the diagram to start a request with it chosen.
Generic four-door diagram, not a glass-fitment diagram.
Windshield
Laminated glass bonded to the body. It is the piece most affected by cameras, sensors and coatings.
Door glass
The front and rear windows that move up and down. Each side is a separate part.
Vent glass
The small pane at the front of a front door, ahead of the main door glass. Not every vehicle has one. Driver and passenger sides are separate parts.
Quarter glass
The small fixed pane behind the rear door or beside the cargo area.
Back glass
The rear window. It usually carries defroster lines and sometimes an antenna.
Roof glass
A sunroof or a fixed panoramic panel.
Repair or replace
Not every chip can be repaired. The size, depth, location and condition of the damage all matter, so the glass is assessed before a recommendation is confirmed.
- A small chip away from the edge is often a candidate for repair.
- Cracks that reach the edge, damage in front of a camera or in the driver's direct view, and damage through to the inner layer usually point to replacement.
- Side and back glass is usually tempered. It shatters into small pieces and is replaced, not repaired.
Laminated and tempered
Laminated glass is two sheets bonded to a plastic layer between them. When it cracks, the pieces stay attached. Windshields are laminated, and so is the side glass on some vehicles.
Tempered glass is a single heat-strengthened sheet that breaks into small, blunt pieces. Most side and back glass is tempered.
One windshield, many versions
Two vehicles of the same model can take different windshields. These are the features that change the part.
- Camera mountDriver-assistance cameras look through this area. Replacing the glass can mean the camera needs calibration.
- Rain and light sensorBonded to the inside of the glass beside the mirror on vehicles that have one.
- Head-up display zoneHead-up display windshields use a special interlayer so the projected image stays sharp.
- Heated wiper parkFine heating elements along the lower edge on some vehicles.
- Frit bandThe black ceramic border. It shields the adhesive from sunlight.
- Glass stamp, or bugThe etched mark with the maker's name and codes such as AS1. Glass shops call it the bug or the monogram.
- VIN windowThe clear cut-out that keeps the vehicle identification number readable from outside.
- Third visor bandThe dotted shade behind the mirror. It cuts glare in the gap between the two sun visors.
- Auto-dimming mirrorA mirror that darkens by itself at night. It is wired, so its mount on the glass can differ.
- Logo in the glassSome makers print a small emblem in the black band, for example on some Jeep, Ram and Ford Mustang models. The badge here is a stand-in.
Camera calibration
Many vehicles have a forward-facing camera behind the windshield for lane keeping, automatic braking and similar features.
When the windshield is replaced, the vehicle manufacturer may require the camera to be calibrated: in the shop with targets, on the road, or both. The requirement depends on the vehicle and the work performed, and it is verified for each request.
Reading the glass stamp
Every piece of automotive glass carries a small etched stamp, usually in a lower corner. A clear photo of it helps identify the part.
- MakerThe glass manufacturer's name or logo.
- Glass typeLaminated or tempered, often written out.
- DOT numberA code that identifies the company that made the glass.
- AS markingAS1 is windshield glass. AS2 can be used anywhere except the windshield. AS3 is darker privacy glass used behind the driver.
- M numberThe manufacturer's own model number for that piece of glass.
