Tesla buys its glass from Saint Gobain.Tesla makes their own glass. I believe the Tesla has IR heat rejection in their glass. Rivian clearly has not much IR heat rejection. I put Llumar Air 80 on all the privacy glass (roof, sides, back) and windshield on the R1S. This seems to have helped cut the heat and reflect the sun away from the car. Will know more with testing![]()
