Could you explain the different types of auto glass? Yesterday, I found that a tree branch had smashed the back window of my car and cracked the side window. When I called an Auto Glass Replacement Company to see what it would cost to fix it, they asked if the window that was broken on the side of my car was the back window, vent or quarter glass. – Jessica, Atlanta, GA

It’s important to know the different types of auto glass so you can give more detailed information to the auto glass technicians prior to their arrival.

6 types of auto glass on a typical vehicle: the front Windshield, front and rear door auto glass, vent glass, quarter glass, and back glass.

Windshield Auto Glass

The most important type of auto glass is, of course, the windshield. It not only shields you from the wind as you are traveling. It provides up to 30% of the roof support. The passenger side airbags often bounce off the windshield before expanding to protect the passenger. It is often tinted to improve the driver’s visibility.

Front Door Auto Glass & Rear Door Auto Glass

The front door auto glass and rear door glass can be different because of how they are tinted. In the state of Georgia, the windows to the right and left of the driver can not have tinting that reduces the light transmitted to less that 32% or light reflectance increased more than 20%.

Back Glass / Back Window Auto Glass

Back Glass has the same restrictions concerning window tinting as the windshield, front and rear door auto glass.

Vent Glass & Quarter Glass

Vent and Quarter glass can be tricky just because they can be different sizes depending on the make and model of the vehicle.
