Mine is almost identical. The very bottom line is different. I’m not sure what that is. I also have the insulated glass option.That's interesting. I didn't post an authority for the side windows only statement because I - like @ct-andy - was told this by my Porsche dealer. It is certainly possible, as there are many vendors who sell acoustic windshields to manufacturers (such as AGC). There is a way, supposedly, that we can tell (e.g., here).
We have a unique advantage, however, as we can compare cars (hopefully). My car DOES have the thermal and sound insulation option. In the lower left (passsenger) corner of the front windshield, there is a parts code. If someone (in the US) who does NOT have the thermal and sound insulation option can do the same, then perhaps we can settle this for certain. I will say that the A/IR code that I have circled in red suggests the possibility that, contrary to what some of us have been told, the windshield in the thermal and sound insulation is different. The “A,” I believe, stands for “Acoustic” and the “IR” for infra red or thermal. Let’s see if someone can post an image to compare!
I can confirm that is true, side Windows and Roof Glass are the only insulated glass. Replacement rear window, non-insulated, was identical to the one on the vehicle. A bit unsure that it won't happen again (window cracking), if the glass is identical, we'll see.
Yes some owners have had problems with the noise insulated glass option and cell reception. This has been confirmed in threads and by a dealer I am going to buy mine from. He indicated some have had serious problems with cell reception and some have not with the insulated glass option. I wanted to get the option myself but decided it wasn’t worth the risk as cell reception is non negotiable for me.
None here. My iPhone works annoyingly well with the glass option.
Not to derail thread, but I wonder how soon 'soon' is
Yes mine was a 2022 build from the get-go - pandemic impacts on timing a def frustration but hopefully you get lucky!
So i’m wondering, where did this discussion end. The A/IR glass comes from the additional noise and thermal insulated glass ? Or only the windows are double glass
