OEM and aftermarket glass
At a glance: OEM glass is made for the vehicle maker; aftermarket glass is made by others to fit. Both must meet FMVSS 205. The shop says OEM can cost two or three times as much and quotes aftermarket first[2][3].
What do OEM and aftermarket mean?
“OEM” glass is made by or for the vehicle maker and usually carries its logo. “Aftermarket” glass is made by another company to fit the same opening. The shop’s cost article defines OEM as “original equipment manufacturer” glass and says it “usually costs more than high-quality aftermarket glass, though both meet the same safety standards”[1]. The federal rule supports the second half of that sentence: FMVSS 205 applies to glass “intended for aftermarket replacement” just as it does to factory glass[2].
How big is the price gap?
The shop’s OEM article says original glass “can cost double, even triple the price of aftermarket windshields”, that shops generally quote aftermarket first as “the best value for the money”, and that an OEM quote can be requested and is “sometimes” not far off[3]. It publishes no price list. Its cost article lists what moves the price: the size and curvature of the glass, how common the model is, the glass type, built-in sensors or heating, and insurance coverage[1].
How does the shop compare the two?
| Point | OEM glass | Aftermarket glass |
|---|---|---|
| Fit | “Exact fit and high quality” | “Fit might not be as precise” |
| Price | “Generally more expensive” | “Usually cheaper” |
| Availability | “May be less readily available” for older or rare vehicles | “Generally more widely available” |
| Insurance | “More likely to be covered” | “Coverage can vary” |
Quoted from the shop’s home page[4]. On safety, the same table says aftermarket glass “may not meet the same stringent standards”, which sits uneasily with the cost article’s statement that both meet the same standards[4][1]. The legal position is the one in FMVSS 205: both must comply[2].
What about cameras, sensors and heated glass?
This is where the choice matters most. Windshields on many recent cars carry rain sensors, heating, acoustic interlayers, heads-up display zones or a bracket for a driver-assistance camera[1]. The Insurance Institute for Highway Safety has found that a basic windshield might cost about $250 to replace, while cars with front crash prevention were more likely to have glass claims of $1,000 or more[5]. The shop says replacement glass will have whatever electronics the factory glass had[4]. Whichever brand is fitted, a camera mounted to the glass will usually need calibration; see camera calibration after replacement.
Will insurance pay for OEM glass?
That depends on the policy. Texas regulators describe comprehensive coverage as paying for glass damage from causes such as hail or flying gravel, minus the deductible[6]; TDI notes that an insurer is only required to pay for parts “of like kind and quality” to those damaged, so the policy and the original glass decide which grade is paid for. Ask the insurer before the job, and ask the shop to quote both if the difference matters.
How can I tell which I got?
Read the mark block in the corner of the glass. Vehicle-maker glass usually shows the maker’s logo alongside the glass maker’s details; aftermarket glass shows the glass maker’s brand. Both should show “DOT” with an NHTSA code and, on a windshield, “AS1”[2]. See reading the glass label.
Where does used glass fit in?
The shop also sells used original parts, a third option alongside new OEM and new aftermarket[7]. For side windows and older cars, used original glass can be the only exact match. Texas law requires that any replacement be safety glazing, and imperfect glass must be labelled as such[8].
