: dual-pane acoustical glass

I have heard that the side windows are dual-pane acoustical glass. Are all the windows dual-pain acoustical glass including the windscreen and rear window?

I don't believe the side windows are dual-pane glass-- if so, it's not mentioned in the brochures or on the Cadillac web site. I've seen this on some Lexus and BMW models a few years back, but I don't know if anyone's doing it any more. It's super expensive and you can get similar results with active noise cancellation and other systems.

There has never, to my knowledge, been dual pane windshield and rear window glass. That said, some automakers are using "acoustic glass" in windshields (my 2011 SHO is an example), but I don't know how it's different from regular glass.

I did some more research and they are "Laminated windows" not Dual-pane.
