The only difference is if the glass has a OE name plate (GM / Ford / Chrysler / Toyota / etc) on it or not . They are identical in every other way. All windshields are required to have an AS1 rating and be DOT approved.

Sorry Dave, but my uncle works for PPG and he tells me differently. PPG makes both OEM and aftermarket glass. They are not made in the same plant. OEM glass is slow annealed for one thing and aftermarket glass is not. That's one reason aftermarket glass has more stress cracking and chips easier. It is not, in fact, the same quality glass. Slow annealing takes longer so production is slower, hence it is more expensive.
Aftermarket windshield glass is made from a copy of a mold of an OEM windshield, not from the windshield’s original mold in the factory. Just so you understand what the OEM term means in this glass arena. So aftermarket windshields may not be to the exact dimensions or the glass may be too thin or have distortions. This results in leaks, increased road noise, and possible failure of the glass in an accident.
I really don't see much difference in any of the aftermarket junk be it body panels or glass. It's cheaper and there is a reason it is cheaper. I posted all those links as evidence that aftermarket is not the same qualitywise as OEM and these links point that out with some clarity.
But listen, if you want to believe differently be my guest. I don't really care. I choose not to risk my life or my family's on aftermarket crap.
Guess you chose to go with aftermarket. Drive carefully.
If that was the case, do you really think your insurance company would open themselves up to that kind of liability?
It's not accurate to compare sheetmetal to glass. A/M glass is cheaper because you're cutting out the middle man = The Car Manufacturer. Many A/M sheetmetal parts are notorious for being inferior(for several reasons). That's why only a few insurance companies(Geico/Progressive/Allstate) choose to utilize them. Most don't, including the one I work for. Glass on the other hand, is totally different. Every insurance company(well maybe not Chubb) will opt to go with non-dealership(A/M) glass unless your vehicle falls under their mileage/age guidelines. Do you really think insurance companies would open themselves up to this liability? Provide me with info showing a lawsuit where an insurance company was sued because the A/M glass they allowed failed during a crash. Make sure that improper installation isn't the reason either. Until then, I'll have a totally clear concience about all the A/M glass I adjusted for.
