Decoding information from, well, code between glass panes

I'm getting conflicting information about what kind of double glazing was really installed at my place, and wish to get to the bottom of the matter.

There's a code stamped in between the window panes. It reads

 

"SAINT-GOBAIN GL JAR 28/11/22 SGG Climaplus 295x1782 3626391/24  PLASTBUD  SP. Z 0. 0"

for the fixed panes and

"SAINT-GOBAIN GL JAR 28/11/22 SGG Climaplus 387x1782 3626391/25  PLASTBUD  SP. Z 0. 0"

for the panes in the middle (which do open).

 

Here 28/11/22 is obviously the date of manufacturing, whereas 295x1782 and 387x1782 are the dimensions. But what can one deduce from the rest of the string? In particular, what do I learn there about the thickness of the different panes of glass, the width of the space between them, the dB rating, etc.?

 

(It may also be the case that one can deduce from the above that the glass was manufactured for Saint-Gobain somewhere in Poland; if so, that's completely unsurprising - the contractor is Polish. Now I know, for instance, that one can get Polish paint in specific colors from the Farrow Ball catalogue, such as "Winsome Persimmon" and what have you. But that's another story.)

Google found this pdf but I don't think it helps any. Not enough info on the lable you have?

 

https://nl.saint-gobain-building-glass.com/sites/saint-gobain-building-glass.com/files/2019-10/CLIMAPLUS_BRO_BENL.pdf

 

 

 

My guess is that "3626391/24" codes some valuable information in a compact way. Unfortunately the code seems country-specific: Saint-Gobain glass made in France uses one code, Saint-Gobain glass made in Poland uses another code. I thought perhaps someone here could play Sherlock better than I can.

It turns out that "JAR" stands for "Jaroszowiec" - more specifically, "Saint-Gobain Glassolutions Jaroszowiec". I've written to them - I'll call on Monday.

Do you know if the glass has a costing on it?

 

A costing? What do you mean?

Yes....This pdf in polish has similar format numbers at the bottom..

Right, that's how I located the city in Poland.

Since it's got dimensions the 3626391/24 could be an order number and pane number. Eg pane 24 and 25 of order 3626391 ?

 

Well, I have eight panes, four ending in 24 and four ending in 25.

 

3626391 could be an order number, or it could be a descriptor. In other Saint Gobain glass, the code can be looked up online:

 

https://www.saint-gobain-glass.fr/fr/services/naviglass-la-carte-didentite-de-votre-vitrage

 

However, my codes aren't even in the right format (they should be 12 digits long).

 

You'd expect that I should at least be able to look up my windows' code in https://glassolutions.pl/pl/  , but no - or at least I haven't found anything there myself (even with the help of automatic translation).

Are all those numbered 24 the same size so they can go anywhere where that size is needed. Ditto the 25?

Climaplus is from the Planitherm range of coatings from Saint Gobain and I believe it's from Planitherm One range, there's a specific way of referencing the spacer to determine origin, manufacturer, coating, date of unit being made and production run, bath number etc. and most of it is useless to the end user and not important.

 

Simple answer to the question, is speak with supplier/manufacturer and ask them to supply you the glass data sheet. The can easily supply this from the glass supplier or run this through Calumen to give you the answers. If not, ask them for the glass thickness, spacer bar size, overall unit depth, gas used and the coating applied and I'll give you the answers you're looking for.

Right (and thanks). The problem right now is that people at the factory all answer the phone in Polish, and say they don't speak any of the languages I do speak. I'll have to ask a distant relation...

Send an email, unusual as usually they speak decent English.

 

”proszę o arkusz danych technicznych szkła użytego w zamówieniu 123456. Jeśli arkusz danych nie jest dostępny. czy możesz potwierdzić grubość szkła dla każdej szyby, zastosowany gaz i procent, a także zastosowaną niską powłokę. Dziękuję”

 

change 123456 to the order number.

 

”please may I request the glass data sheet for the glass used within order 123456. If the data sheet isn't available. can you confirm glass thickness for each pane, the gas used and percentage, in addition the lowe coating used.

thank you”

Oh, thanks! I already wrote to them in chatGPT-aided Polish (I know just about Polish to make sure that chatGPT was not selling my soul, say). They haven't replied yet.

 

Good news, though: the contractor just sent me the sheet with information! I'd rather it state things like thickness - it just gives a sound rating, which seems a bit optimistic:

 

"Isolation au bruit aérien direct (dB)                     3                        45(-1;-5)"

 

See attached. Hopefully there's enough data on this sheet that we can figure out everything?

I was writing a long post and apparently it got lost. Let me be more succinct. 

 

The line "CLIMAPLUS SILENCE PLANITHERM XN F3 44.1Si(20 argon)10" at the top of the page gives the specifications:


one layer of 44.1Si glass

20mm of argon,

one 10mm-thick layer of glass.

 

Here 44.1 is a standard, and 44.1Si is some sort of magical 8mm glass from Saint Gobain, with "Si" standing for "Silence" - see https://www.saint-gobain-glass.fr/fr/produits/stadip-silence#performances

 

While the table at https://www.saint-gobain-glass.fr/fr/produits/stadip-silence#performances doesn't quite have a configuration that is exactly equal to that, it has one that is slightly worse (less spacing) and one that is a bit better (somewhat thicker glass); interpolating allows us to confirm that the claimed dB value is plausible (or at least consistent with the table), and also let us interpret it.

 

Looking at the table, one can see that 45(-1;-5) must mean

Rw = 45dB,  RA = 44dB,   RAtr = 40dB

                      (RA = R + CA,  RAtr = R + Ctr,    so  CA = -1, Ctr = -5
 

These are three different weighted averages of R as a function of frequency.

RAtr is meant to correspond to road noise, with its lower frequencies.

Cool, thanks - this agrees with the data on the sheet.

 

The motivation for all of this was to get the right data so as to decide whether to improve on the sound insulation. The windows are good, but we are talking about a first floor right in front of a two-way street that can get reasonably busy.

 

A window specialist (https://www.different-projet.com/) visited today - he seemed to know his stuff. He recommended adding sliding windows on the outside, with single glazing (designed for sound protection - the term was "feuilleté", which makes me think of croissant dough). That's what I had thought. Now waiting for the quote. Steeling myself...

Forget it to be honest, you really need to consider several factors.

 

1: How the window is installed, a higher dB rating on the glass is pointless if the installation is not looked at properly. I recommend compriband 7/12 and 20mm wide to assist with the noise reduction. Glass can be changed, the installation is harder to do. 

2: The type of noise is important, is this road traffic noise and pedestrian noise? It may not necessarily be travelling through/around the windows, but through the ground and up for example.

Right. That's why I won't consider doing it myself, and I'm trying to do this with a specialist rather than with my usual contractor. Just got a quote from the said specialist - now I'm trying to bargain...

The most annoying thing by far is road traffic noise, and particularly motorbikes. Large buses and the occasional lorry do not bother me much, which is just as well, as there's only so much I can do against the low frequencies, in part perhaps for the reason you mention.

One can occasionally hear people talking loudly, but, if I manage to basically get rid of motorbike noise, I take chattering humans will be taken care of as well.
