What Is OEM Glass?
OEM stands for Original Equipment Manufacturer. OEM windshield glass is made by the same supplier that produced the glass originally installed in your vehicle at the factory. For example, if your Toyota Camry came with a Pilkington windshield from the factory, an OEM replacement would be another Pilkington glass made to the exact same specifications.
OEM glass guarantees:
- Identical fit and seal geometry
- Matching UV coatings and tints
- Compatibility with rain sensors, heated glass, and embedded antennas
- Certified ADAS camera compatibility
What Is OEE Glass?
OEE stands for Original Equipment Equivalent. This glass is manufactured to meet (but not exceed) OEM specifications. It's made by third-party glass manufacturers like Pilkington, AGC, or Guardian who produce glass that fits OEM specs without the factory brand label.
Quality OEE glass from reputable manufacturers performs nearly identically to OEM and is significantly less expensive. Most insurance companies cover OEE glass as the standard replacement option.
What Is Aftermarket Glass?
Aftermarket glass is a broad category that includes anything not made to OEM specifications. Quality varies enormously. Low-end aftermarket glass can have:
- Slightly different curvature that causes installation gaps
- Missing or incompatible sensor zones
- Different tint or UV characteristics
- Poor fit that leads to wind noise or leaks
AutoGlass Rehab does not use low-quality aftermarket glass. We use OEM glass or high-quality OEE from certified manufacturers only.
When Does OEM vs. OEE Actually Matter?
The distinction matters most in three situations:
- ADAS-equipped vehicles: Some camera systems — particularly on certain BMW, Mercedes, and Tesla models — require OEM glass for proper calibration. We'll tell you upfront if your vehicle is one of them.
- Luxury vehicles under warranty: Dealer warranties may specify OEM parts. If your vehicle is still under a manufacturer warranty, check with your dealer before accepting OEE glass.
- Heated windshields: Some vehicles have heating elements embedded in the glass. OEM glass ensures the electrical connectors match perfectly.
Which Should You Choose?
For most vehicles and most situations, quality OEE glass is the right choice — it performs the same, costs less, and is covered by your insurance. For ADAS-intensive vehicles or luxury models, OEM glass provides peace of mind that the fit and calibration will be exactly to factory specs.
