Automotive glass is an umbrella term for the glass that’s used in car windows. Whether you’re a car owner or someone who’s still looking to buy their first vehicle, you should know the different types of automotive glass and what they’re for.
Someday, you’ll need to have them repaired or replaced. If you know exactly which glass you need, you can save time on assessment. You can also avoid repair shops that will try to cheat you by offering services which aren’t really necessary.
The front windshield is perhaps the single most important auto glass. Its main purpose is to protect the passengers from wind, insects, and flying debris such as dust and rocks – while giving a clear view of the road in front of them.
Unknown to many, the windshield also supports 40% of the car’s structure. In the event of a collision, it prevents the roof from caving in and passengers from being ejected.
The rear windshield is equally important, serving similar functions as the front windshield. The only difference is that it’s meant to give a view of what’s behind your car.
Most rear glass windows are fixed in place, while others open with a hinge or slider. It is typically embedded with an antenna, defrosting wires, and it’s own wipers.
Front Vent Windows
These are small triangular windows that are found on the sides of the vehicle, just behind the front windshield. They have their own frames which have been fitted into the window and door frame. You can also open and close them independently of the side door windows.
Front vent windows are common in older vehicles. Newer models have replaced them with single piece of molded door glass. They’re called such because they were designed to let in air on hot days. Now that air conditioning is a standard, they are no longer used.
The quarter glass can be found on the rear body panel, at the opposite end of where the front vent windows are. Unlike the front vents, they can’t be opened. A quarter glass provides the driver a view of what is typically a blind spot.
Side Door Windows
These are the car windows which are immediately adjacent to the passenger seats. Those that are beside the front passengers are called front side door windows, while those at the rear are called rear side windows.
Side door windows can be rolled up and down using a manual lever or an electronic button. Some cars are equipped with a child safety feature that prevents rear glass windows from rolling all the way down.
Sunroofs and moonroofs
Also known as panoramic roofs and all-glass roofs, both types of auto glass are usually found on higher end vehicles. They can open in two ways – either you tilt them up like a vent or slide them open.
Sunroofs and moonroofs allow natural light and fresh air to enter the cabin. Passengers can also view the sky as they please, which makes the ride more relaxing.
