If you roll down a front and rear window. Then compare the edge on both. The front on mine has an edge shaped like an M. The rear has a rounded edge. The windshield has a small gap where you can feel and see it also. Not as well but it is there. As for laminated, all window glass on a vehicle is laminated. Not just the windshield.
Dale,
Not all glass on a vehicle is laminated. On most vehicles just the front windshield is most often the only piece that is laminated. Some vehicles are now incorporating it on the first row side windows. A very small number of vehicles are adding laminated glass to the 2rd row. Otherwise all these sections of glass minus the windshield are only required to be TEMPERED glass, including the panormaic sunroof.
Only a few manufactuers such as Tesla, Volvo will use laminated glass for sunroofs.
The reason your 2rd row glass feels different is because it does not have the laminated piece of glass in the middle because the 3rd row glass is tempered ONLY.
Before recently buying my explorer, I test drove a 2021 Jeep Grand Cherokee L and Jeep is advertising this vehicle as having an acoustic windshield, acoustic first row glass, and amazingly also having acoustic 2nd row glass. When I visually checked all 5 pieces of glass, everyone of them surely indeed said "Acoustic" or had an acoustic indicating symbol.
This is where my contention is with the 2020-21 Ford Explorer glass. Whether the glass is laminated on the windshield and first row side glass was never a question. I want to know if the glass is "ACOUSTIC laminated glass" .
And just like the Jeep Grand Cherokee L I test drove and any other manufacturer that puts acoustic glass on a car, every piece of glass will display markings that it is acoustic.
I find it very bizzare that our glass has no such indicators with such robust advertising of these features and the fact that Ford has for a long time, and based on cars I JUST saw in the showroom, utilize their Sound Screen acoustic windshields and which had probably the most conspicuous acoustic indicator in the business, but leaves the glass on our Explorer's a mystery.
Before my explorer, I had a 2020 Hyundai Palisade, which has acoustic glass on the windshield and first row side windows. Sure enough it had markings indicating as such. I also test drove the newly designed Nissan Pathfinder and it also now has an acoustic windshield and first row side glass and is marked as such. These are all in addtion to the Jeep Cherokee I drove above which had acoustic markings all all glass that was supposed to be.
What I am getting at is that acoustic glass is becoming a big deal these days and Jeep is even pushing the bar further by starting to do it in the 2nd row. When these manufacturers say the car has acoustic glass, from my experience, you can be damn sure the glass will be marked as such.
