If you can get the part numbers I don't see why not but the better solution would be to just have film applied to the glass that has these properties. Many modern window film (tinted or not) have the same capabilities for heat and noise reduction. Much cheaper and less invasive installation process.

Thanks. I didn't know modern films can also help with noise reduction.
Now I'm thinking of how much heat and noise reduction I'd get if applied such film on a car that DOES have this type of glass haha.

I remember reading that this was done on a W213 chassis. I searched, but couldn't find it, but I remember the member that did it said the door cards needed to be changed as the glass is thicker. I'm not sure if double-paned glass, but thicker that required different door cards. I'm pretty sure I remember that right and something to dig into deeper as it could get expensive.

My '18 E300 (W213) has option 596 HEAT INSULATING+IR REFLECTG.SAFETY GLASS ALL-ROUND. It has 2 panes with an IR reflecting film sandwiched between them. There are two small areas on the windshield that allow for dashboard equipment such as transponders to function. Last year when road debris broke the windshield a replacement had to be obtained from Germany.

Acoustic glass has two layers of glass sandwiched between a film. You can add tint/film to block IR, but not do much for sound. Theoretically you can replace all the window and windshield glass with acoustic glass but doesn't seem practical.

You have that backwards. The film is sandwiched between two layers of glass. On my car it is part of the PAF package.

There must be something to it. My wife’s E450 with double laminated glass is the quietest Mercedes we have had and it is on RF tires. Actually this is an all round superior automobile.

I got my windshield done in 70% ceramic film. A stock windshield is in the range of 70% tint (very light tint), so I really don't notice it being dark. I wanted the UV blocking properties of ceramic tint, and it does work.
