Hi Guys,
I guess it depends on your definition of Laminated & Double Glazed.
You can have single pane laminated glass, usualy for shatter resistance. The 'sticky backed plastic' layer is there to stop it all falling apart for safty.
Double glazing certainly has various materials between it, usualy a blend of gasses, but i don't see why having a film layer in the void stops it being double glazed. The glass is definately two panes and the change of density between them is what slows the sound penitration.
Either way, i think they are excelent. They stop noise and make the car a much more impenitrable place for burglers and for safety
