A8 "break in" review

[jayzee]

Double glazed = 2 paynes of glass with an air gap between them.

Laminated = 2 paynes of glass which are bonded together with no gap.

So are your windcreens double glazed then?



ETA - Look at the 7 series LWB; that has double glazing i.e. with a gap, and not disimilar to the type found on houses.

Range Rover in 2005 went to laminated side glass, and in 2007, this was changed to double glazing.

here is what double glazing looks like on a car - much thicker due to the air gap.

* Two panes of window glass or other transparent material.

So it guess as it does have two paines of glass it is double glazed?

Audi call it double glazed

[darrenjoe90]

they may be double glazed and harder to get into but its no impossible as i found out at the begining of this year


but at least a nice policeman gave me a parking ticket or two to hold it back in place


autoglass told me after i paid my excess that the glass would have cost over £600 to replace

One the second pane has been broken, that's it, the integrity of the window is done for. You could see that in the video too.

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???

[jayzee]

I have no idea, was the only thing I could find on the net.

On the Long wheelbase 7 series and 2007 onwards Range Rover, the edge of the glazing is similar i.e. a frame that holds the glass in place, keeps it airtight and spaced etc. When you wind the window down, it looks weird having this frame.

It's basically like a sealed unit for a house window.

Double glazing "with gap" is proven to be quieter than laminated (a la A8 D2), and this is the reason Land Rover only went with laminated side glass for a couple of years before going with proper double glazing on the Range Rover.

Pedantic? Me? Never


http://www.youtube.com/watch?v=S0RwLIWYeLI look at 0.27 sec on this clip - see the band around the glass? It's all I could find on the net!

They are double glazed according to Audi, just rang customer services to find out the spec of an 02 S8 and the lady says it has double glazed windows on the system.

[jayzee]

Well, Audi are technically incorrect.

Double glazing is two pieces of glass with a gap between them.

I have checked with a colleague, who works for Pilkington - he confirms this too.

The windows on the S8 are laminated.

Oi you stop driving the prices and our bragging rights down

If I didn't know any better I would say your one of them BMW drivers...
