OEM and aftermarket describe how replacement glass is supplied, but the manufacturers behind those products can overlap. A company may produce original glass for automakers while also offering replacement glass through the aftermarket.
That overlap does not mean every aftermarket windshield is identical to the original. The specific part, its features, and the vehicle manufacturer’s requirements matter more than the brand name alone.
What Standards Must Replacement Auto Glass Meet?
Replacement auto glass sold for use in the United States must meet applicable Federal Motor Vehicle Safety Standard No. 205 requirements. This standard addresses safety glazing performance and incorporates ANSI/SAE Z26.1.
Compliance is a safety baseline, rather than proof that two windshields have identical specifications. The replacement must also be appropriate for the vehicle’s equipment, including camera mounts, head-up display, heating, and other glass features.
Pilkington (NSG Group)
Pilkington supplies original equipment glass to vehicle manufacturers and replacement glass to the aftermarket. Its automotive business serves both markets.
That makes Pilkington an example of a manufacturer with both OEM and aftermarket involvement. However, the brand name alone does not establish that a particular aftermarket windshield is identical to the automaker-branded version. Confirm the specific part and its suitability for your vehicle.
On some vehicles, you may find Pilkington’s name on the original windshield. Checking the glass marking can help identify its manufacturer, although the replacement part’s specifications still need to be confirmed.
PGW (Pittsburgh Glass Works)
The PGW name has a history in original equipment glass manufacturing, but an important distinction applies: Vitro acquired PGW’s OEM glass manufacturing business in 2017. The aftermarket distribution business remained separate.
When comparing replacement options, distinguish the company supplying the glass from the manufacturer identified on the glass itself. Purchasing through PGW does not, by itself, establish who manufactured that particular windshield or whether it is an OEM part.
AGC Automotive and AP-Tech
AGC Automotive serves both original equipment and replacement glass markets. Its replacement-glass business supplies automotive glazing through aftermarket distribution channels.
You may find AGC markings on original vehicle glass as well as replacement products. As with Pilkington, confirm the specific replacement part and its features rather than assuming every windshield from the same manufacturer is identical.
AGC also distributes replacement glass under the AP-Tech brand in the Americas, so you may encounter either name when comparing glass options.
Saint-Gobain Sekurit
Saint-Gobain Sekurit supplies original equipment automotive glass. The group also serves the replacement market through Sekurit Service, formerly known as Autover.
This is another example of OEM manufacturing experience extending into replacement glass. Availability depends on the vehicle and market, so ask which specific glass product is being quoted and whether it includes your vehicle’s required features.
Fuyao Glass
Fuyao manufactures automotive glass for both original equipment and replacement markets. Its aftermarket business draws on the company’s OEM manufacturing experience.
Fuyao’s involvement in both markets illustrates why an aftermarket brand may also appear on factory-installed glass. The specific replacement part still needs to match the vehicle’s equipment and applicable requirements.
Choosing the Right Replacement Glass
A manufacturer’s OEM experience can help explain its background, but the specific glass part matters most. When comparing options, ask:
- Who manufactures the glass being quoted?
- Is it an automaker-branded OEM part or an aftermarket replacement?
- Does it match your vehicle’s camera, head-up display, heating, acoustic, and sensor features?
- What do the vehicle manufacturer’s replacement procedures require?
