Understanding OEM Auto Glass
OEM auto glass stands for Original Equipment Manufacturer auto glass. This type of glass is made by the same company that supplied parts for your car when it was new. It matches the exact size and shape needed for a perfect fit in your vehicle.
Since it comes directly from the original maker, this glass meets all the safety standards required by law. These strict guidelines ensure that each piece of glass can handle impacts well and protect passengers during accidents.
This kind of window may also work better than aftermarket glass for cars that have advanced driver assistance systems, like lane-keeping help or adaptive cruise control. Since these features rely on sensors that can be affected by how light passes through glass, using OEM ensures everything functions as intended.
Although often more costly than alternatives, insurance policies may cover the expense because they help ensure compatibility with high-tech onboard systems.
The Manufacturing Process of OEM Auto Glass
The process of making OEM auto glass begins with finding the right materials. Manufacturers choose high-quality sand, soda ash, and limestone to melt together at over 1700 degrees Fahrenheit. This mixture becomes clear liquid glass that can be molded into windshields. Experts then cool it down slowly to prevent any cracks or imperfections.
Next, technicians cut the cooled glass to match specific car models perfectly. They use precise machines for this task to ensure each piece’s size and shape are exactly right. After cutting, they embed technology such as lane departure warnings or collision mitigation braking systems directly into the glass. This integration allows the windshield to work seamlessly with a car’s advanced driver assistance system (ADAS), improving safety and performance on the road.
Understanding Aftermarket Auto Glass
Aftermarket auto glass is produced by various suppliers for vehicles after they leave the initial manufacturing site. Unlike OEM glass made by or for car manufacturers, aftermarket versions might not be built to the same specs. Sometimes this causes a difference in fit.
Aftermarket windshields often cost less than OEM ones. However, consumers sometimes find problems such as distortion in the view through the glass or thinner materials that may affect durability. Some aftermarket options do not align well with cars’ safety features like lane-keeping assist and forward collision warning systems. Because of these items, choosing a replacement windshield involves more than looking at price tags.
Is There a Difference Between OEM and Aftermarket Glass?
The main difference lies in their manufacturing. OEM windshields are made to match the original car window that came from the factory exactly. They fit like a glove because they are made using the same specifications and materials as your first car window. This ensures everything from clarity to shape is the same as how your vehicle came from the factory.
On the other hand, aftermarket windshields may or may not hit those same marks. The difference in OEM vs aftermarket largely lies in not knowing whether or not aftermarket glass is designed to the same specs as OEM glass. Aftermarket windows should still meet the same safety standards as OEM windshields, but may differ slightly in fit, optical clarity, or durability compared to OEM versions.
Some drivers choose them because they cost less, especially for expensive replacements or when insurance coverage considers price. However, if your car has special features like lane-keeping assist systems or blind spot detection, an OEM windshield could be necessary to keep these systems running smoothly without glitches.
