What is Vent Glass?
Vent glass is probably the most confusing automotive glass part there is. A lot of this has to do with the history of automobiles and left-over naming conventions.
Let’s get into it!
What is Vent Glass?
Traditionally, vent glass is a small piece of glass located on the side of your vehicle near your windshield. It’s usually a triangular shape. Not all cars have vent glass near the windshield.
The triangular-shaped glass near the windshield is called “vent glass” or “front vent glass”. Not all vehicles have vent glass.
More recently, vehicles can have rear vent glass towards to back of the vehicle. This is where things can get confusing.. The reason why is it can get confused with quarter glass which is usually the last piece of glass on either side of the vehicle near the trunk or the back.
Some vehicles will only have quarter glass..
Some vehicles will have front vent glass, rear vent glass and quarter glass…

Some will have vent glass that could pass as quarter glass…
In some rare cases, triangular glass at the rear of the vehicle will be called rear vent glass, even though it could pass as quarter glass.
So how do you know what rear vent glass is?
The answer we have is:
- Vent glass does not roll up or down. It’s usually fixed in place. However, on older vehicles, vent glass can rotate on it’s vertical axis to open.
- Any triangular-shaped side glass that’s located at the front or rear of the vehicle.
- The glass between the quarter glass and the rear door window.
Why Is Vent Glass Called Vent Glass?
Cars made during the middle of the 20th Century (1940s – 1980s) had vent glass that one could open. Usually by rotating the glass along its vertical axis. This allowed the passenger cabin to “vent” or let in fresh air without having to roll down a side window.

Can You Replace Vent Glass On Vintage Vehicles
It really depends. Once we start talking about vehicles made before the 1980s, acquiring glass parts can become more difficult. Especially, when we are talking about vent glass.
For classic automobiles, it’s usually not a problem. Cars like Mustangs, Camaros, Novas, 56 Chevys, etc., vent glass can be easily obtained. For something like a 1961 Fiat, that’s another story. It doesn’t mean vent glass CAN’T be obtained, it’s just not in the normal supply chain. You may have to get the glass off eBay or from a used car parts store. Sometimes junk yards will be able to get it from their yard if the car is in their lot.
