When your windshield is replaced, you'll be offered OEM (Original Equipment Manufacturer) glass or aftermarket glass. There is a price difference between the two options. Here's what actually matters and how to choose.
OEM glass is manufactured by the same supplier as your factory windshield — companies like Pilkington, AGC, or Saint-Gobain Sekurit. It's identical to what came on your car from the factory: same thickness, same curvature, same acoustic interlayer, same black ceramic frit border.
Aftermarket glass is manufactured to approximate OEM specs, but not by the original supplier. Quality varies significantly. Top-tier aftermarket brands (Carlite, PGW) are nearly equivalent to OEM. Budget brands may have slight thickness variations or inconsistent UV coating.
Vehicles with forward-facing cameras (Tesla, Honda Sensing, Toyota Safety Sense, etc.) are particularly sensitive to glass thickness and optical quality. A 0.1mm difference in glass thickness can shift the camera's focal point enough to require recalibration. OEM glass minimizes this risk.
For vehicles without ADAS cameras — older cars, trucks without safety systems — quality aftermarket glass performs identically to OEM in safety and durability. The structural integrity (laminated construction, PVB interlayer) is the same. For these vehicles, aftermarket can cost less without any practical downside.
Auto Renu uses OEM glass by default on all ADAS-equipped vehicles. For non-ADAS vehicles, we use OEM-equivalent aftermarket glass from PGW or Carlite. We never use budget-tier glass. Every installation uses industry-standard urethane adhesive with a 1-hour drive-away time.
