This is great information. Except.... What about the back glass that I have seen in some of these pics that are only partially red? It would stand to reason for me that, even with 4 different manufacturers that red tint would be an either/or thing.

I agree, I'm upset about this. I called service center and discussed it, they has no explanation and said they would look into it. I already had an appointment to bring my car in next week so we added this to the other to cover while the car is there. I'm unsure that anyone really knows whats going at this point. Its a bummer to say the least, the glass doesn't match and we don't know if the protective properties are different or not, these are independent but important items to me. Its an all glass roof and I expected the glass pieces to match and they do not. I also don't want more heat, I was concerned about heat to begin with and now more so. its depressing to spend $70K and not get what I expected to get.
Is the orange on the roof related to UV or IR, does anyone know this answer for sure?
i did after i wrote my post but still not sure what your point is, I must be missing something, would you mind spelling it out for me? Its been a long day.
Just to be very clear I love my car, its amazing, I just didn't expect to have two different kinds of glass making up the roof. Dual motor Midnight Silver Metallic.

Same build and same (differing) glass... I just want them to be the same at this point... Provided all the iterations offer the same UV protection, I don't really care if they both don't have the cool effect or if they do... I'd just like them to match.

I agree with this. Also, would have been nice to have some communication about this...but I've realized in dealing with Tesla that communication is not their strong suit...or a suit they own at all.
Thank you Garlan. Actual data demonstrating that whether the glass looks orange in the rain or not, it blocks the same amount of UV. And that the glass is much better than what Tesla was using in 2013.
Sure it blocks UV, but how much IR does it block? After all wasn't it the IR blocking property that causes the orange/red appearance to water not the UV blocking?
@Garlan's post is certainly informative and very appreciated. However, I think there's still an important question that Tesla hasn't answered: IR blocking.
Note that UV blocking is usually built into the glass. Therefore, whether or not the glass roof has coating has nothing to do with the % of UV blocked. IR blocking, however, is completely based on the coating. A case in point is the 3M Crystalline film that I use for my existing cars. If you look at the specs, they are very similar to the lower-priced films EXCEPT they block 97% of the infrared rays which makes a HUGE difference in cabin temperature. Therefore, IF the "new" non-colored window does not have the IR coating, it's certainly a step backward and should be investigated.

I may be wrong, and its happened a lot in the past but UV is what causes you to have a sun tan, Infra Red radiation is what causes things to get hot. I'm not sure that concentrating on UV performance is what the focus should be.

I don't disagree. Someone who is concerned about this should go get their glass tested for IR and report back, ideally comparing with another owner with the different glass. Otherwise, this thread is generating unsubstantiated information that then gets taken as fact.
There's actually a quite simple way to test this. Those infrared temp guns would do. AFAIK the front glass still has that orange hue. So all one needs to do is to let the car sit under the sun for a bit say 30 mins w/o AC, then point that thermometer at both the front and the back glass and compare. If there's a significant difference in temp readings then you have your answer right there.
Wouldn't it be nice if Tesla just told us what is going on? It would go a long way to solving everything.

Why should they? They made the switch from Alcantara like material to cloth late last year...folks complained like they are now with this change...but in the end sales kept going up. Its not like we have a choice...just enjoy the car.

I guess. If I hadn't read this thread, I wouldn't have even noticed that my (soon to be) car is different than earlier models. They've likely changed suppliers for many parts. It's complete speculation here that the specs of the glass have changed even if the appearance has. If it's proven the glass is inferior to older glass, then have it and get Tesla to do something about it, but otherwise it's 4 pages of noise.
