I think its evident from the video that the inner 'sandwich filling' is what gives the outer glass sheets their integrity, once they have started to fragment.
Does it really matter if its called laminate or double glazed. Had there been nothing but gas between the two panes, then the hammer would have been through them in next to no time. The glass would have collapsed and left the entire window area open.
I've always assumed that the Audi thinking was along the lines of..... We want superior soundproofing. Thicker glass = improved soundproofing. But thick glass also = lots more weight. We've just invested millions to create a significantly lighter aluminium body, can we achieve superior soundproofing without the heavy glass penalty. Yes. Simple. Use plastic and put a thin sheet of glass on each outer surface so that it still has the wear resistance of glass. Bingo! Lightweight glass with really good soundproofing qualities.
When the marketing people got their hands on the project, thanks to Mercedes, they already understood the cachet of 'double glazing'. And here were windows made with two sheets of glass. In fact (if not spirit) it is double glazing. and its a great marketing tool. Lets be honest, its a good one to drop in the pub.
jayzee. The picture of a window that you've posted, isn't that armoured glass???
