Default Automotive window glass codes

If you look closely at your car's side glasses or even the front windshield and rear/hatch glass, you would note quite a few stuff imprinted on the glass. ISI mark is prominent. Along that, there is

# Car manufacturer's name [Ford/Skoda]

# Glass manufacturer's name [Saint Gobain/AIS]

# And a code which is marked by E and is followed by numerical, like E2 [Scorpio], Yeti [E8] IIRC, Figo [E4]

What does this decipher to? Thickness of glass? Hence the poor insulation inside a Scorpio and pin drop silence in the Yeti or Figo? One moment, I hopped from a Swift to a Polo and could instantly feel the amount of noise [external] which got cut and couldn't filter in.

Apart from other parameters which aid NVH, IMO thickness of glass too plays an important role.

Would love to know, what those spooky silent high end Germans come with, what code/s?

Finally, the question is, do those numbers denote thickness?

The "E" means that the glass has been approved for road use in Europe on European member licensed automobiles by the Economic Committee of Europe (ECE). The number next to the "E" indicates the country which approved the item.

The numbers are as follows:
1 - Germany;
2 - France;
3 - Italy;
4 - Netherlands;
5 - Sweden;
6 - Belgium;
7 - Hungary;
8 - Czech Republic;
9 - Spain;
10 - Yugoslavia;
11 - United Kingdom;
12 - Austria;
13 - Luxembourg;
14 - Switzerland;
15 - (vacant);
16 - Norway;
17 - Finland;
18 - Denmark;
19- Romania;
20 - Poland;
21 - Portugal;
22 - Russian Federation;
23 - Greece;
24 - (vacant);
25 - (vacant); and
26 - Slovenia.

Quoting a post by PatchyBoy from another thread:

3. Logo of Asahi

4. Manufacturing Licence of unit conplying with IS specifications. This particular number in the picture translates to - 2081844 Asahi India Glass Ltd, 94.4Kms. National Highway-8, Vill.-Jaliawas,Tehsil-Bawal, Rewari, Haryana, Pin - 123501

5. E code. indicates the country that certified the windshield. E2 is France

6. TP-M33A - This is the model number of the glass. TP here means tempered, 33 means 3.3mm thickness and A means for use in Automobiles. Since tempered glass has other than auto use as well the 'A' is used. This is unique to the manufacturer.

7. 43R-001264 - certification according to EU standards

8. Identification of the manufaturing time frame of the glass. Not sure how to dechiper this code, but let me try and guess. My car was purchased in Dec 2007. Manufactured in Oct 2007. The glass has 07....

From this I am guessing that the glass was manufatured in April 2007

This picture has 09 ......

Applying the above logic, this glass must have been manufactured in June 2009 and this car must have been manufactured / purchased some time in the July - Dec 2009 time frame. This is only a guess and could be incorrect.

If the windshield of a car reads "transparency 70%", then what does that mean? Is that a tinted glass?

Default Re: Automotive window glass codes

Sometime back, at a Land Rover event, had observed glasses of various models of their vehicles. Interesting observation was that there was no one manufacturer from whom glasses were installed. Different glasses were from Fuyao, Saint Gobain - Serukit, Pilkington in there vehicles.

This is from Range Rover - Evoque. Notice the code for HUD display.

Window glass from Evoque

This one has code for rain/water repellent properties
Automotive window glass codes-range_rover_rain.jpg

This one seems to have code for shatter proof?

This is the land rover discovery window glass. Has an acoustic code. Filters out noise?
