Default I read somewhere that the JDM R has a thinner windshield then the USDM R, True?

I forgot where I read that...

True or False???

Could some one show me hard evidence either way?

Now how about getting one of those new in the US?

For those who wonder why one would have a thinner glass, its for weight savings.

I know it has been discussed but I can't recall any proof being shown.

I've worked in the automotive glass industry before and there is very little chance the glass is any different. It might have some different standars it has to meet for Japan but the weight is likely no more than 2-3 pound if they really did change it (Which I doubt).

I have also heard the rear hatch glass is lighter. I wonder if there's any truth to that....

I read in CAR magazine that the NSX-R has thinner glass too.

Probably a JDM only thing similar to bumper requirements, emissions etc.

Weight savings would be minor though.

Yes.. JDM R has thinner glass.. USDM got thicker because of DOT safety requirements..

not sure about the hatch glass, as I've never heard specifically about it, but it's probably the same deal..

I found out in the Honda EPC/EPS that the USDM ITR has the same windshield as the the GSR. And the JDM/Euro ITR windshield is different and made by ASAHI.

The windshield and hatch glass of the NSX-R are the same as the non-R version of the NSX.

In the NSX, there is a pane of glass between the passenger compartment and the engine compartment. In most NSXs, this is actually a double-pane of glass, with a vacuum between the two layers of glass, to reduce noise intrusion into the cockpit. The NSX-R sold in Japan, and the Zanardi NSX sold in the States in '99, use a single pane of glass (obviously with no vacuum). This resulted in a weight savings of 4.2 pounds. This is probably what the article you read was referring to.

Yes that is correct. The glass in the JDM is not Shatterproof. Our glass when in an accident spiders out, their glass just breaks and shatters everywhere. It is a little thinner because it doesn't have the film and second layer of glass.

Bingo!

Also Since I work for a large auto glass Co I might just look into getting the lighter one cause mine has a small stone chip. But its out of the way and has not spread (not worth changing yet).

But first things first, repairing the damage from the accident takes first place

I have also heard that the NSX has a lighter windshield along with many other weight saving items such as a Al spare tire jack

my car came with the same galss as the usdm cars. how do i know? thev have the same D.O.T. with some number stamped on the glass. but its not a R, i doubt they change it. i think honda makes one glass to meet all standars, cheaper that way. but since glass over there don't have to meet D.OT. one could buy an aftermarket glass that is thinner and lighter.

Our glass is called "safety glass". The windshield is laminated, which prevents glass from injuring occupants if something hits it (which is most likely for this piece, since it faces front). The side and rear windows are made of tempered safety glass, which shatters into small pieces without sharp edges when broken, protecting occupants in the event of a crash. This is a great idea, because it means that you are not likely to be injured from the car's glass in the event of an accident. You can read more about safety glass here.

Given the benefits of safety glass, I would be surprised if Honda didn't use it in all their markets...

I would just have the chip repaired (NJ insurance covers this, not sure about NY). My understanding is that chassis rigidity is compromised slightly whenever a factory windshield is replaced, due to differences in the OEM and replacement installation processes & materials. This tradeoff (and monetary expense) would probably not be worth the few pounds of weight savings, if they even exist.

I would, too. Aside from the money - and Padawan is right (furthermore, many insurance companies even waive the deductible for windshield repairs) - why risk leaks and/or damage to your car from replacing the entire windshield if it's not really necessary?

One franchise that repairs damaged windshields is Novus. You can find out more information about it on their website here.

They fit the windshield on, and then use a adhesive to make sure it stays on.

It'd be hard to believe that chasis rigidity can come from the windshield. If it did, anytime we'd get into an accident, etc, then the glass would shatter/break, even if the glass had zero contact.

Chasis rigidity comes from guess what?

Actually on some cars it adds between 20-50% more rigidity, And will crack if the car is struck hard enough.
if installed correctly by using the right amount of urethane, the urethane acts like a shock absorber to a decent amount. But if the car flexes too much then the glass will crack.

Putting a windshield in a car has to be done right from the start or the installer is creating a hazard for the operator and passengers of that vehicle.

I completed a short course at work just a few weeks ago.

Here are two quotes that will make you think about having your glass installed by a hack.
"It is one of the greatest safety features found on a vehicle today, but it is also one that we take for granted- our windshield. Eleven million windows are replaced each year, but as a recent 20/20 news investigation uncovered, a great number of these windows are replaced incorrectly.

Windshields do a lot more than just keep the rain and dust out- they deflect the airbag and keep the roof from caving in on top of you. They also prevent you from being thrown out of the vehicle in a collision.

The National Glass Association is an industry group that has certified more than 10,000 installers nationwide. They offer some suggestions for safe windshield replacement.

Stick with installers certified by the NGA. Your chances of getting your windshield safely replaced will increase.
Insist that a strong automotive grade adhesive be used to bond the glass.
Don't let the glass be installed on corroded metal.
Follow- to the letter- the directions given by your technician.
Drive the vehicle only when the adhesive has fully cured (dried and hardened), usually about 10 hours.
Always wear seat belts and insist that all passengers wear them too."

"Even if you wear your seatbelt and have a properly functioning airbag, without a windshield firmly bonded to your car, any safety precautions are worthless. Your factory installed windshield prevents the car's roof from caving in and deflects your airbag. An improperly installed windshield is likely to come out during an accident - just when you need its protection most."

I'd like my windshield to be THICKER.

&lt;--- got 7 stone chips on the windshield

Are you sure about this?

If the JDM and Euro ITR has the same windshield it definately is shatter proof as i took a heavy hit from a stone in mine with the result beeing a large chip in windshield, it most certainly is laminated glass or it would have exploded in my face.

Don't be afraid. Laminated windshield is also compulsary in Europe and Japan. Only the glas is thinner. You can read at the label of the windshield, it says "Lamisafe".

You don't happen to know the different part #'s on the windshields do you? I'm planning on replacing mine and want to make sure i get the right one ( i don't trust my local stealership to much )

All windshields are laminated. Even JDM counterparts. Just like all door/backglass is tempered. And nsxtasy mentioned it would be silly for Honda not to utilize these safety features.

Bbsaso made a good statement about proper windshield installation. This is crucial to safety, screw rigidity for performance sake.

USDM glass in the Type-=R and any other Japanese manufactuerd Integra also used ASAHI glass (Notice the name corelation?). If it is a United states produced piece of glass for hondat it will read "AP Tech" which is a join venture between Asahi and another company I don't recall.
