I was given a '98 750iL and noticed the the windows have this 1" black strip around the edges. Is this something standard on the 750il? I own a 740il and that strip is not there.

The 750iL has insulated (thicker) window glass to help reduce sound as standard equipment. This thicker (laminated) glass many times gets miscontrued as protection or security glass. If it was the latter...the rear windows wouldn't retract down into the door all the way, and there wouldn't be any rear window switches on the driver's door.

Just wait till you see the price tag when they start to delaminate and it is time to replace.

Thanks for your reply. With this lamination on the glass, is there a problem with having them factory tinted?

Just to humor me today, what is the cost?

The local dealership here wanted 1,600.00 per window.

That sound more like they were looking at the "protective" glazing which is more "resistant" to objects thrown or projected toward the glass in the event of threat or harm.

If you click the link that 04ssd has in his reply, you can scroll down the part nbr index and see that #2 for PROTECTIVE GLAZING costs a lot more than the regular and insulated glazing (this glass is in the 740iLP & 750iLP). :)

And then there's the actual SECURITY glass which comes in the 750iLS (offered in other markets that are more volatile) where it will actually stand up to a military assault: http://www.realoem.com/bmw/showparts.do?model=GK01&mospid=48544&btnr=51_2123&hg=51&fg=05

The glass in the SECURITY models cost more than what our cars are worth! :eek: The security windshield costs approx $26k and the side windows cost approx $18k ...but as you can see in the pics below...they can save your life...like the Defense Minister of Sri Lanka....he walked away with just a little blood on his shirt in an attack on his convoy back in December/2006:

BMW does not reccommend tinting the double pane glass. With the known delamination issue, the tint is likely to make it worse from heat build up. And, there is a plastic laminate on the inside that you would be putting the tint onto. Not actually on glass. I am experimenting however. I put tint on my quarter glass panels only over a year ago and so far so good.

Yeah mine is definately not the protection type that would prevent a bullet from entering the cabin, but it is the break resistant as unfortunately I have a crack on the drivers side from a golf ball incident.

So have you called your insurance then? I have a $500 deductible with Allstate but that's a lot less than paying the full $1500

why run insurance? The glass is $400, that's $100 less than the deductable

The glass is not $400 if he has the double pane insulated or security glass. It's $1200 plus installation.
And if it is the regular $400 glass, a lot of insurance companies have no glass deductible anyway.

maybe you failed to click the realoem link. The regular single pane glass is $165.17, the dual pane is $400.64, the Security glass (non protection) is $1182.96. The dual pane and security glass looks identical, the thickness is the same as they are both dual pane. And the Dual pane is less likely to delaminate than the security glass. Click the link above that I posted. I didn't pull the prices out of my arse, that's the list cost.

I've posted this a bunch of times before but here goes, these are the 4 different types of glass.

1) Normal = Single pane, no tint, ~4.5 mm thick, $200
2) Insulated = Double pane, slight gray or green tint and has a black border around glass, ~9mm thick, $500
3) Protective/Security = Double pane, slight gray or green tint and has a black border around glass, ~9mm thick, $1100
4) Bullet-Resistant = Multiple layers, no tint, black border around glass, also has metal band around glass, ~40 mm thick, $5000

The #2 and #3 glass are identical looking yet one is more expensive (the #3) because it is resistant to breaking open (not cracking... it will crack pretty easily). #3 also delaminates much easier and worse than #2. If you have a thick black border around your windows and they are delaminating badly, you most likely have #3 glass.

The suggested path to take is to replace with #2 glass, however you should talk to a glass shop first and see what they can do. Also, you can not have the dealer install the glass if it is different from what the car originally came with, and if you get it installed by a third party, you will "lose" the BMW parts warranty (ie: they wont honor it because they will use the other installer as the blame). So find a good glass shop and figure out what kind of glass you can retrofit with.

Good luck.

PS... If you can get a good deal and find some good labor, you can also retrofit all the glass with the single pane glass, check on bimmerboard.com for an example of this. It can be easily done, just requires all the parts which is why most havent done it. Also takes a good amount of time. But might be worth it since there are plenty of sources for the single pane glass now that it would be fairly cheap compared to repairing with the other glass types.

we retrofitted Melissa's delaminating security glass with single pane in a few hours up in NorCal this past January. It can be done but it requires alot of work, plus all the single pane glass parts including window rubbers, gaskets, window regulator pieces and so on.

Mine is the protective security, or number 3. I have delamination issues on all four, and in the summer time its even more noticeable. I think I am going to check into moving down a notch to number 2, the cost savings would be very nice, I do not mind spending around 2K to do all four windows, would surely beat 6K.

Try getting the retrofit to the single pane. Should be even cheaper, but you would have to be comfortable with doing all the work. Try calling around some junkyards and see if you can get all the parts you need from one place.

Another idea is to just replace the whole doors (and switch out the interior panels since you have the upgraded leather in the 750).

I think Dinan S3 was referring to post #8 and the pics of the 750iLS (the security model not sold in the USA) and the Sri Lankin Defense Minister. The 750iLS has even more expensive glass than what comes on the protection 740iLP & 750iLP models...that glass cost $26000 for the windshield and $18000 for the side windows! :eek:

Also, if you have the thicker glass #2 or #3. It's PITA to find a window regulator. I'm still looking for a rear left that is decently priced. It's going to be my 4th on an 8yo car. FYI 150 for single pane 300+ for dbl pane regulators. I'm about ready to seal the rears.lol

True but the double-pane regulators are more reliable, mine havent skipped a beat.

CORRECTION: the regulators are apparently the same, BMW has tricked me again with their snazzy part numbers...

I did "seal" the rears. It's a little button on the drivers door so the kids won't play with the windows :D

The window regulators are the same price for single pane and dual pane glass. The only difference is the way the glass mounts to the regulator, we used dual pane regulators in Melissa's conversion. All we had to do was change the mount on the front regulator. It was easily converted. I am almost positive the regulators are identical with the exception of the one mount.

You are absolutely correct Colin. The mount was the only change. :buttrock

Ah, the ultimate E38 mod...after you've got your 32" big brake kit with slotted/drilled/etched/shaken-not-stirred rotors, your 9-speed manual tranny and 24 psi super-duper-charger, tires that can grip on the ceiling, a Strong Strut that makes Chuck Norris afraid, and a cold air intake that also makes ice cubes for your rear seat's Sub-zero walk-in refrigerator, then you're ready for the 750iLS glass.

You have to admit, though, that $100K in window glass is a small price to pay if you're a country protecting your head of state. Those pictures always amaze me.
