Acoustic glass windows & windshields

I asked my S.A. point blank this question today during a test drive and he said yes front and sides are acoustic glass.

My spec sheet provided says acoustic glass and wasn’t trim specific.

Seemed pretty quiet inside.

I saw an article that only the luxury and overtrain trims have both acoustic glass on windshields and side. Others only has the acoustic glass on the windshields ?🤷🏻‍♂️
 
Bumping an old thread: can anybody confirm which models (if any) have ‘acoustic glass’ vs regular glass & the difference between the two.

My front passenger window cracked on my premium plus and there were not different part numbers for that and luxury. Seems like they all use the same glass.

Makes sense to me. Some rando on FB claimed the OT+ had it while the OT did not. Couldn’t find anything online about it
 
My early dealer spec sheet from when I ordered 2 years ago has all trims having acoustic windshield glass

OT+ has acoustic front side glass and OT did not

Premium, luxury, executive trims had it but signature ( base ) trims did not.

These are the Canadian trims btw

Whether that made it to final production who knows.

Was wondering if that was the case. Thinking USDM spec is all the same
 
Per a Canadian spec sheet, all trims except the standard OT have acoustic glass

 
It appears that on my lux+ the front windows have acoustic glass. But not the rear windows. You can see the multiple layers on the front and just a single layer on the back. What do you guys see?

The front windows are laminated glass the back are tempered. Not sure that has anything to do with acoustic, but it explains why you see layers on the front windows.

I learned a lot when my passenger window cracked my first week of ownership and I found out about it being on national back order. Still not convinced my glass wasn’t damaged during the shipping process. Didn’t seem like a rock chip to me but no way I could prove it.
 
Owners manual says all GX 550 have laminated (aka acoustic glass). Page 508. If you look up same in the LC owners manual you will see the LC only has laminated in the windshield.

Lexus has a foot note “if equipped”. the OT does not have the laminated glass on the front windows.

On my premium, only the front windows are laminated and have “Lamipane” etched into the glass. The rear windows are tempered and etched with “Temperlite”. The windshield is “Lamisafe”. Just look at each window etching to verify.

Not true. Laminated glass is designed for safety and keeps the glass intact when shattered. Acoustic glass is specially designed for sound reduction.

True, but although not true “Acoustic” glass, Lexus uses that term in its marketing of laminated glass as the laminated dual pane has better sound attenuation than a single pane of tempered glass.
