Laminated Glass Retrofit

Ok I finally installed my laminated glass today!

Since someone broke one side, I decided to change out both sides with the laminated glass on my 2020 model 3.

A few things I learned.
1. Most importantly: it's a direct fit. Two bolts on the bottom, same as the old one. The new ones have the bracket attached to the glass rather than a separate bracket on the older ones (on the old ones they use painters blue tape to keep the bracket in place before installing so it doesn't fall out...crazy!). The glass sits flush when the window is closed. Looks just like the new ones.
2. You don't have to remove the second inner plastic panel to change out the glass. If your glass isn't broken, you just remove the the interior panel (3 bolts and some clips). Then you move the window up to a point where you can access the 2 bolts thru 2 holes which you will see after you remove the interior panel (covered by black rubber tabs). While the old glass is still on, use a sharpie to mark where the old glass sits near the tab. When you put the new one in, you want to line it back with those sharpie marks for alignment purposes.
3. Took the glass guy 10 minutes to do the non broken side. Seemed pretty easy to do. On the broken window side, it took longer since he had to remove the 2nd panel to vaccum out the broken glass pieces.
4. Now that I've seen it done, it seems to be a fairly straightforward job. If it takes you longer than 30 minutes to do, then you are doing something wrong.
5. Does it make a difference? If you go below 40 mph, and there isn't much road noise or wind noise, it does seem a bit more insulated. If a car drives by, etc. However at 60 or 70 mph, there is just so much noise coming from everywhere, it doesn't seem to make a difference at all.
6. Another thing to keep in mind....Tesla doesn't have a lot of these. It took me 3 weeks to get mine and the guy claimed they had to pull it from the production line. Not sure if that was really the case...but just know it takes a long time to get.

Hope this settles the glass retrofit question!

I ordered it through my glass shop who directly went to the parts department. Via the app, they just give you the standard glass...so you actually have to talk to the parts guy.

After having it for a day, at low speeds or stopped, the glass does seem to isolate the cabin a bit from external noise. For example if a car drives by or people talking outside. Those noises does seem more muffled. Maybe its just in my head! I don't know...there must be a reason all the higher end car companies use laminate glass.

However, on the freeway, I can tell you, for sure: there is no difference. There is just so much noise coming from everywhere else.

I have noticed that driving our 2018 M3 in winter the drivers window frost's over below 10F, even with normal cabin heat on. I recently watched a video from Bjorn and he pointed out that his 2018 always frosted up as well, but the 2021 he was testing out didn't frost over and it was -20C out, he also said it didn't feel as "cold" from the wind as his car. So it has to help with heat loss as well and heck even being able to see out it would be worth it...

If you can get a hold of the part, it takes less than 30 minutes to do. If you are handy, probably 15 minutes. Attached picture with the red arrows is where you access the bolts that hold the glass. Just remember to mark where the old glass sits thru those holes so you can line the new glass up to them and not have to worry about adjusting it.

I highly doubt it's the glass. More likely the HVAC upgrades.
