Would the words "laminated" stamped on the window be a dual pane glass?

 

If you look down on the window glass you'll easily be able to see if it's single or dual pane. The duel pane will be like two pieces glued together. My front drivers and passenger door glass was replaced by Lexus because it was only single pane. The 2 ply glass has really cut down on the wind noise I once had. I don't think "laminated" appears on either single or 2 ply window glass.

What or where did that manual page come from? I don't think I've seen that guy in any literature I've gotten.

Thanks,
