A guide to rear windshields & their features

Simple and intuitive, the rear windshield (or rear glass) is located opposite of the front windshield, and is located in the back of the vehicle, sealing it off from the outside. Similar to the front windshield, the rear windshield is one of the types of auto glass that helps your vehicle keep its rigid frame, as well as protecting occupants of the vehicle.

Other than that, how this particular pane of auto glass is made, functions, and feature, set it apart from the front windshield.

How is the rear windshield made?

Unlike the front windshield, the glass for the back windshield is made in the same way that auto glass is made for the side window, vent window, or quarter glass panes: tempered glass. The back car window glass is strengthened by thermal or chemical treatments so that it can withstand blunt force, but will shatter into tiny, granular chunks of glass instead of shards. This is a feature of tempered glass and is often called “safety glass” for this reason. 

What are some of the features of the rear windshield?

The rear windshield comes in all shapes and sizes, depending on what kind of vehicle you are driving. Most cars have a rear windshield that is completely bonded to the rear of the frame of the vehicle, while some trucks have sliding panes called “truck sliders” or ones that open outwards on a hinge so that air may circulate in the vehicle or provide additional room for larger loads. Some vehicles have rear windshield wipers to wipe dirt and water off of the rear windshield, so the rear view is not obstructed.

If you experience damage to your back windshield glass, get the auto glass repaired right away.

What are those lines on my rear windshield?

All rear windshields must be clean and clear so that the driver can utilize the rearview mirror properly when changing lanes and reversing. The lines are thermal and integrated into the rear defroster, which runs a small current of electricity to heat the rear windshield pane.
