OEM windshields are made by the original manufacturer of your vehicle, not by a third-party glass company
OEM stands for Original Equipment Manufacturer. An OEM windshield is glass produced by the same company that made your car — Toyota makes Toyota windshields, Ford makes Ford windshields, and so on. When you replace a windshield with OEM glass, you are installing the exact type of glass that came with the vehicle when it left the factory.
The alternative is an aftermarket windshield, which is made by a separate glass manufacturer like Safelite, Pilkington, or Guardian. Aftermarket glass meets federal safety standards but is not produced by your vehicle's maker. Most insurance companies cover windshield replacement but often steer customers toward aftermarket glass because it costs less.
The choice between OEM and aftermarket matters because the two differ in cost, fit, and sometimes in features like tinting or sensor compatibility. Understanding those differences helps you decide whether to pay extra for OEM glass or accept an aftermarket replacement.
Key Takeaways
- OEM windshields are made by your vehicle's manufacturer and typically cost 20 to 50 percent more than aftermarket glass.
- Aftermarket windshields meet the same federal safety standards as OEM glass but may have minor fit differences or lack features like rain sensors or acoustic dampening.
- Most insurance policies cover windshield replacement but often include a deductible and may require you to use an in-network glass shop.
- OEM glass is sometimes necessary if your windshield includes integrated features like heads-up display compatibility or advanced driver-information sensors.
- You can request OEM glass from most repair shops, but you will usually pay the price difference out of pocket if your insurance does not cover it.
How OEM and aftermarket windshields differ in cost and installation
An OEM windshield typically costs between $400 and $1,200 depending on your vehicle make and model, while an aftermarket replacement usually runs $200 to $600. The price gap widens for luxury vehicles or models with integrated technology. A Tesla or BMW windshield with embedded sensors or heating elements can cost significantly more as OEM than the aftermarket equivalent.
Installation time is usually the same — most shops complete a windshield replacement in one to two hours. The labor cost does not change based on whether the glass is OEM or aftermarket. What changes is the material cost, and that difference is what you pay if your insurance does not cover it or if you choose to upgrade from the aftermarket option your insurer offers.
Some repair shops stock both OEM and aftermarket glass on-site, while others order OEM glass when you request it, which can add one to three business days to the job. Aftermarket glass is usually available the same day or next day because shops keep it in inventory.
When your windshield includes sensors or special features
Modern vehicles often have windshields that do more than let you see the road. Many include rain sensors that trigger automatic wipers, heads-up displays that project speed and navigation onto the glass, or acoustic dampening that reduces road noise. Some windshields also have heating elements or are tinted to reduce glare.
Aftermarket windshields may not include these features, or they may require additional installation steps to make them work. A rain sensor, for example, sits behind the windshield and communicates with your vehicle's computer. An aftermarket windshield without the sensor bracket or wiring harness will not trigger automatic wipers even if your car has the feature.
If your vehicle has integrated windshield features, OEM glass is often the simpler choice because it comes with all the necessary components and brackets already installed. Some aftermarket shops can retrofit these features, but it adds cost and complexity. Check your vehicle's manual or ask your repair shop whether your windshield includes integrated technology before deciding between OEM and aftermarket.
What insurance typically covers for windshield replacement
Most comprehensive auto insurance policies cover windshield damage, but the coverage usually comes with a deductible — typically $250 to $500 — that you pay out of pocket. Some policies offer $0 deductible for glass-only claims, though this is less common. A few states require insurers to waive the deductible for windshield replacement, but most do not.
Insurance companies almost always direct you to use a shop in their network, and those shops typically install aftermarket glass as the default. If you want OEM glass, you can request it, but your insurer will usually only pay what they would have paid for aftermarket glass. You cover the difference yourself.
The exception is if your vehicle's windshield includes integrated features that aftermarket glass cannot replicate. In that case, some insurers will cover OEM glass at no extra cost to you, though you may need to provide documentation that the feature is necessary. Contact your insurer before scheduling the replacement to ask whether they will cover OEM glass for your specific vehicle.
How to request OEM glass and what to expect
When you call a glass repair shop or your insurance company's claims line, tell them you want an OEM windshield. Most shops can order OEM glass for any vehicle, but they will quote you the full price — both what insurance covers and what you pay. Ask the shop whether they have OEM glass in stock or whether they need to order it.
If the shop needs to order OEM glass, expect a wait of one to three business days. Some dealerships also offer windshield replacement and may have OEM glass available faster because they stock it for warranty repairs. Dealership replacement is usually more expensive than an independent shop, but the speed and certainty of OEM availability can be worth it if you need the car quickly.
Before you schedule, confirm with your insurance company whether they will cover any portion of OEM glass. Some policies allow you to submit a claim for the aftermarket price and then pay the difference yourself. Others require you to pay the full OEM cost upfront and then request reimbursement for the aftermarket amount. Knowing the process ahead of time prevents surprises at checkout.
Aftermarket glass and why insurance companies prefer it
Aftermarket windshields meet the same federal safety standards as OEM glass — they must pass the same crash tests and provide the same structural support. The difference is not safety; it is cost and sometimes fit. Aftermarket manufacturers produce glass for many vehicle models, so they optimize for cost rather than exact factory specifications.
Minor fit differences are common with aftermarket glass. The trim around the edges might sit slightly differently, or the glass might be a fraction of an inch thicker or thinner. These differences rarely cause problems, but they can affect how the windshield seals against the frame or how it looks when light hits it at certain angles.
Insurance companies prefer aftermarket glass because it costs them less and because aftermarket shops often have volume agreements with insurers. A shop that installs 50 Safelite windshields a month gets a better rate than one that orders OEM glass for individual customers. That cost savings is passed to the insurer, which is why most policies default to aftermarket replacement.
Warranty and durability of OEM versus aftermarket glass
Both OEM and aftermarket windshields come with warranties, though the terms vary. OEM glass typically includes a manufacturer's warranty that covers defects for one to three years. Aftermarket glass usually has a similar warranty from the glass manufacturer, plus a separate warranty from the installation shop that covers the labor and seal.
Durability is comparable between the two. A well-installed aftermarket windshield will last as long as OEM glass. The difference is in how the glass handles stress — OEM glass is engineered specifically for your vehicle's frame and weight distribution, while aftermarket glass is engineered to fit a range of similar vehicles. In practice, this means OEM glass may handle impacts slightly better, but the difference is small enough that most drivers will never notice it.
If your windshield fails prematurely — cracks spread unexpectedly or the seal fails — you can file a warranty claim with the manufacturer or the shop. OEM claims go through the manufacturer or your dealership, while aftermarket claims go through the shop that installed it. Both processes typically take one to two weeks.
Frequently Asked Questions
Can I use aftermarket glass if my car has a heads-up display?
You can, but the heads-up display will not work unless the aftermarket windshield includes the display layer and the shop installs it correctly. Some aftermarket shops can retrofit the feature, but it adds cost. OEM glass includes the display layer by default, so it is the simpler choice if you want the feature to work.
Will my insurance cover the difference between OEM and aftermarket glass?
Most insurance policies will not. They cover the cost of an aftermarket replacement, and you pay the difference if you choose OEM. Some policies make an exception if your windshield has integrated features that aftermarket glass cannot replicate — ask your insurer before scheduling the replacement.
How long does it take to get an OEM windshield installed?
If the shop has OEM glass in stock, installation takes one to two hours. If they need to order it, add one to three business days for delivery. Dealerships sometimes have OEM glass available faster because they stock it for warranty work, but they usually charge more for installation.
Is OEM glass worth the extra cost?
OEM glass is worth it if your windshield includes integrated features like rain sensors or heads-up displays, or if you want the exact factory fit and appearance. For a basic windshield without special features, aftermarket glass is safe and durable, and most drivers see no practical difference.
What if I want OEM glass but my insurance will not cover it?
You can pay the full cost yourself and keep the receipt for your records. Some people submit the claim for the aftermarket amount and then pay the OEM difference out of pocket. Others choose to accept the aftermarket replacement and save the money. The choice depends on your budget and how much the integrated features matter to you.
