ᐅ Is a glass breakage acceptable within the mold?

Here I am again:

The windows are installed. Unfortunately, there were issues such as the attached glass damage, which cannot be photographed clearly with my mobile phone camera once installed, as the image always becomes blurry (glass is difficult to photograph).

This blemish is clearly visible from both inside and outside at a distance of 2 meters (6.5 feet). Do I really have to accept this according to regulations and case law? At least that is the information provided by the representative of the window supplier regarding acceptance.

If so, I would find that unfortunate, as I would then have to purchase a new pane at my own expense... 🙁.

Thanks and best regards

If I did everything correctly, I googled this and read that shells are allowed 🙁

That is no longer in zone F, but H. At least the one on the right in the picture (though the angle is difficult).

Apparently, this is allowed according to the guideline

That is clearly beyond the guideline. It’s normal that you have to prove everything. If you're lucky enough to still be able to pay the invoice, deduct the price of one window. In Germany, it usually works so that the person asking for something is at a disadvantage. If they want the money, they have to prove that the window is okay. If you have already paid, then you have to prove it. And don’t get me started on endless legal arguments. Nothing is free in Germany.

I would be interested in that as well. I would really find it remarkable if such damage were considered acceptable.

Glass Manual -

**8.6 Guideline for Assessing the Visual Quality of Glass in Construction

This guideline was developed by the Technical Advisory Board at the Institute of Glazing Crafts for Glazing Technology and Window Construction, Hadamar, and by the Technical Committee of the Federal Flat Glass Association, Troisdorf. Status: May 2009

----------------------

I’m still a bit clueless and can’t quite assess the photo. Is the shell located in the middle of the glass or near the edge? The gray strip (?) confuses me 😕

"F" would not be objectionable, as it is at the edge; with "H" (pane), the situation looks very different, and the window supplier’s assistant should reconsider.

This concerns the right shell, which is still visible after installation. This means it is NOT on the edge and therefore not allowed. Basically, the guideline states that the shell must not be visible after installation.

As mentioned, as long as payment hasn’t been made, your position is quite good, and it should be a matter of honor to deliver defect-free products. Once payment has been made, you have to consider whether it’s worth making a big issue out of this. If they do not respond properly after a reasonable defect report, you have to decide whether to pursue the matter legally.

Where exactly is the window in the end? A basement window is probably less critical than the representative large glass facade in the living room.

PS: Who actually says that this guideline is legally valid? Building according to DIN standards, for example, is not a given unless contractually agreed upon. Any guideline is not necessarily binding, especially if it is not an official guideline but only called that.

@Bauexperte : I have to admit, I see reflections, a dark frame? lying on the floor with two dents. I can't even estimate the size 🙁
