95 730il E38 rear window replacement ? double glazed or single ?

Hi,

This car originally had a double glazed rear window. The double glazed
replacement window is very expensive, so I am hoping that I can use the
single glazed window for E38 instead?


Can anyone tell me if this will be a problem?



Thanks

I don't think you have a choice in the matter.

There are laws that define the glass that must be used, and it requires two
layers with plastic goo in between them to hold the glass together if it
breaks.

That's laminated glass - different from double glazed.

Double glazed has two sheets of possibly laminated glass with an air gap
between them - to reduce noise transmission.

I know what dual-glazed is, I am not aware of it being available in an
automobile because of the curved surface of auto glass. I was thinking the
OP used the wrong term. Dual glazing in a home is an effort of climate
control -- heat transmission is reduced in a dual glazed window.

Are you saying that they make dual glazed windows for cars? If there is such
a thing, I would guess that the design considerations necessary to support
dual glazing would make conversion back to a single glazed window cost
prohibitive, which should make the decision on which to use pretty easy.

It is.

Used for noise reasons on cars - as I said.

Yes.

The OP reckons it was an optional extra on his car. So it is possible a
standard screen can be fitted as I doubt the body itself is different.

Double glazed or dual glazed windows are an option on some BMW and Merc cars
that on the E65 in the UK is about £2k and it covers both rear doors and rear
screen it is also heavily tinted or sun protection film applied.

I did not know that.
