What's going on everyone? I had a quick question about the security glass feature on some E38's. I am starting to see something like air bubbles inside my drivers side front and rear door glass. Does having this problem make the vehicle less secure?
Can something be done to repair this issue?
If I press on the glass, the seperation seems to go away but eventually returns. Any advice and/or help would be great appreciated...
it happens. nothing can be done and it's very expensive to replace. The previous owner of my car had all 4 windows replaced under warranty. I had two windows replaced under good will when simply slamming the door cracked them. One was my door and the other was my then 5yo closing his. My door is now show bubbles again. Simply very poor product and should have been recalled. you might have the insulated glass rather than security/protective glass (which is NOT bullet proof) define less secure? their is a poly film sandwiched in the middle and another on the inside of the glass. It's meant to hold glass shards from flying like when you see a windshield smash.
I read one post where window tint was applied to the outside of the glass and hid the bubbles very well and the tint was holding up through car washes.
That is disappointing that nothing can be done. I am pretty sure it is the security/protective glass, it is double paned, if I am correctly saying that?
So as simple as closing the door to hard can make something like this happen? That tint on the outside is different, I may have to try it. I think one door is someting crazy like $800 from the dealer to replace?
the security glass and insulated glass are both dual pane. hard to tell them apart.
my drivers door cracked twice. once I know i slammed it hard from the outside. (argument with female involved), second time was just getting in and closing it. my 5yo cracked his getting in and closing.
the protective glazing list for $1080 for rear and $1558 for front. http://www.realoem.com/bmw/partgrp.d...46&hg=51&fg=05
The true bullet proof stuff runs $6k!

Security glass is like 8 layers thick. Insulated glass is argon filled. Question is, do you have a sunroof?

Oh yes, that sounds about right. Those are the close to the prices I was quoted to replace them. I have a sunroof, I know it is not bullet proof. I know it is extremely thick, which prevents it from being shattered. There is a bubble in between the layers that seems to be able to be rubbed out. I just can not justify spending that kind of money to have it happen all over again as soon as the warrenty runs out. Bad design/engineering uh?
That is not correct. The terminology BMW is very confusing. Protective glass, which is also known as security glass, and insulated glass are both dual pane and about 3/8" thick. There is a huge difference in price however
The bullet proof glass has no name but is listed at $6000 and is about 1 inch thick.
See previous links I posted.
Ditto what RI is trying to say....there are multiple types of glass (glazing) and it can get confusing.
The "protective" (aka break-resistant security) & "double insulated" glass look very similar to one another and both have two panes of glass. These 2 options were offered on the regular e38 sedans...which can still have a (glass) moonroof or a (steel) sunroof:
The glass in the the protection & security models... 740iLP/750iLP & 750iLS is different than the glass used in the regular e38 sedans...with the glass in the 750iLS costing much more (about twice as much) than the glass used in the protection models. And these models do NOT come with moon or sunroofs.
The "security" model (750iLS) can withstand attacks like this:
Attack on Sri Lanken Defense Minister's convoy Dec/2006
....and you can walk away looking like this:

That's good info, I will have to ask the dealership which glass is installed so that way I am informed. I know these cars are built solid but damn. This guy only had a few scratches after all of those bullets is quite shocking.
I checked both links out and the bullet proof glass is extremely expensive, I don't think the windows can roll down on those installed.
Fronts do, rears don't.

Question - Does anyone know whether you can replace security glass with insulated. I have a 1999 740il with delaminating glass. I bought replaceme glass off of eBay that I thought would fit, and it did not. To add insult to my self-imposed injury, my mechanic chipped my original glass putting it back in and now my front passenger window is cracking before my eyes. I would buy new insulated glass at $400, but not the new protective at $1300. I would appreciate Any thoughts...
I also wonder if converting from dual,to single is an easy fix. Unbelievably, BMW Service had no idea.
Thanks,

As long as you got glass for an E38, the security and insulated are identical in appearance and size. I don't see how it didn't fit. I've interchanged them. They are both 8mm thick.
S352A is the DOUBLE (insulated) GLAZING
S357A is the PROTECTIVE (break resistant) GLAZING
Yes you can swap in single pane. Some say you need new window regulators, others say you can modify (bend and tweak) the ones you have. You also may need to change out the weather strip moulding along the top of the window channel, and you will have a gap at the top of the door panel. More than one person has done this. Use the search feature here. Tons of info and Q&A
many people confuse the 750il insulated Sound Deadning glass with high security glass. the purpose was not for security but to reduce road noise. the differences are here..
ill let u know my results...

Thank you for your responses. Your comments are helpful. The one suspicion that BMW offered about the glass I purchased was that it may have been from a 740i. I am nervous about punching out another eBay purchase if I am going to encounter a similar situation. As it is, I have a pair of front duals in my garage that are collecting dust. I'll keep you posted on my progress.
I have a full set of 4 clear dual pane windows of out a 1996 750il for $1200. I don't want to split up the set unless I get commitments for at least 3 windows.
I also have a right front dual pane with no de-lamination. It does have an aftermarket tint on it that can be removed for $25 or so at your local window tint place. Price is $300 on it.
Yes--I do part out E38's and have a garage full of parts.
Or you can heat up the tinted window ( works best on a hot sunny day ) then take a black garbage Bag and place over the tint, then the tint should peel off as you are pulling away the black garbage bag.Originally Posted by OregonMTB
If that doesnt work, spray water over the tint then place bag over and let it dry.. Then peal it. Hope it works for you!Originally Posted by OregonMTB
