OEM VS Aftermarket Windshields: Whats the Difference?

August 28, 2026

WHEN REPLACING A WINDSHIELD, WHAT IS THE DIFFERENCE BETWEEN GOING WITH AN OEM WINDSHIELD OR AN AFTERMARKET WINDSHIELD?

If you need a new windshield, you may hear two terms during the replacement process: OEM glass and aftermarket glass.

So, what's the difference, and does it matter which one you choose?


The short answer is that both can be viable options, but there are differences worth understanding before making a decision.

Here's what you should know.


What Is an OEM Windshield?


OEM stands for Original Equipment Manufacturer.


An OEM windshield is made to meet the specifications established for your vehicle by the manufacturer. Depending on the vehicle and glass supplier, it may also carry branding associated with the vehicle manufacturer.


For drivers who want replacement glass that closely matches what originally came with their vehicle, OEM glass may be the preferred option.


OEM glass can sometimes cost more than an aftermarket alternative, and availability can vary depending on the vehicle.



What Is an Aftermarket Windshield?


An aftermarket windshield is produced by a glass manufacturer for use as a replacement windshield but is not necessarily the same glass that was originally installed when the vehicle was manufactured.


Quality aftermarket glass is manufactured to meet applicable vehicle safety standards and is commonly used for windshield replacements.


One of the primary advantages of aftermarket glass is that it can offer more replacement options and may be less expensive than OEM glass.



OEM vs. Aftermarket: Which Windshield Is Better?


There isn't one answer that's right for every vehicle or every driver.


The best option can depend on several factors, including:


  • Your vehicle's make, model, and year
  • The availability of replacement glass
  • Features built into or mounted near the windshield
  • Your insurance coverage
  • Your budget
  • Your personal preference


For some vehicles, OEM glass may make the most sense. For others, a quality aftermarket windshield can be an appropriate replacement.


The important thing is choosing the correct windshield for your vehicle and having it installed properly.



What About Vehicles With Cameras and Driver Assistance Features?


Modern windshields can be more complicated than they look.


Many newer vehicles use cameras, sensors, and other technology mounted on or around the windshield for features such as lane departure warnings, automatic emergency braking, and other advanced driver assistance systems.


Because of this, replacing a windshield on a newer vehicle may involve additional considerations beyond simply replacing the glass.


If your vehicle has these features, make sure they're identified when you're getting a windshield replacement quote so the correct glass and replacement process can be determined.



Will Insurance Pay for OEM Glass?


It depends on your individual insurance policy.


Some policies or circumstances may allow for OEM replacement glass, while others may specify or cover an aftermarket alternative. Deductibles and coverage can also vary significantly between policies.


The best way to know for sure is to review your policy or speak directly with your insurance provider.
