I started a thread about this about a year back and a few members who actually work in the glass industry and work for one of the brands I named gave some great insight to the quality of the brands, if you wanted to search around for that. Point being though every company has issues, some more than others its just a fact. You will be fine with any of the three I listed, but even with the best glass company there is still a chance of getting a lemon.
Yes, you did. I work for one of those "other" brands. Ironically, I just had my windshield replaced today. I went with a
Pilkington, perhaps a bit of bias on my part. I'm not going to say who I work for, but essentially the process is simple in the AGR (automotive glass replacement) world. As soon as this glass is no longer an OE product, i.e. it is not produced for direct assembly line cars, the "car kit" (all the glass components) is bid. Depending on the margins and bids, a company can have sole propriety of the car kit, which basically never happens, or the car kit is split into each individual panel. Again, not just one company earns the AGR bid, because what if that one company went under? The development time for one piece of glass is generally a minimum of 3 months. The thing to understand when purchasing AGR glass is, the spec tolerances are 1.5x that of OE glass. Sure it's sold as OE equivalent by insurance companies, but it is not held to the same standard. Often companies who have the glass during original production will maintain the tooling to bend this glass for AGR as well, and when it transitions from OE to AGR, they will also follow the spec deviation.
It's all brand loyalty at that point, but it is a fact that Pilkington makes the best glass in the world.
