Windows from Poland or Bosnia?

I would even say, THE crux.

yes, also

but especially with wide windows -> approx. 1m - the wheat separates from the chaff.
That is when the inner construction (structural engineering!) becomes important. The panes become part of the structure,
so that the window sashes do not warp in a parallelogram-like manner and no longer
close securely. The internal tolerances become very important there.

We ordered windows from Poland (Schüco Profile) and they were also installed by their installers. I have no complaints. A lift-and-slide door is also included. Our building is KfW55 and all the documents were in order. Reed contacts as well as window security RC3 The money we saved, we invested in our aluminum door with side panel and fingerprint. The door cost us just under €2200. It also came from the same company in Poland.

The money that we saved, we invested in our aluminum door with sidelight and fingerprint. The door cost us about €2200. It also came from the same company in Poland.

Very reasonable! - could you tell me their name (preferably by email ~ @ gmx de)?

My dream: security systems from Poland … they can do it :cool:

Our favorite for wooden entrance doors is this one (see attachment). This costs about €5,000 in Poland without fingerprint (gimmick).

I would also like to know which company that is. Is there any reason not to mention them here?
