Buying guide for windows in new construction

So to clarify once again: 99% of people will not notice the difference or only to a limited extent. The [GU] might also simply work with the one stone or brick. Then it is also good that he sticks to it. But please have him say so openly.

The explanations regarding soundproofing, thermal insulation, and safety indeed sound somewhat unplanned.

You will likely not be satisfied with just a little bit of security or soundproofing.

If something is really important to you, then bring in professionals in the respective field and, if necessary, invest the appropriate amount of money or educate yourself. Configuring a window a little or relying on the general contractor is not effective. If something is not important, you can better save the money and invest it in the things that matter.

That is why I had also written at the beginning that I would like to inform myself in advance here and am grateful for opinions, I really don’t understand what is supposed to be wrong with that. You have to start somewhere.

Just my advice, I felt the same way. Some things just don't fit together here: passive windows and the energy saving ordinance for houses, the stones and the desire for soundproofing. Formulate goals and then implement them consistently.

If you worry about every little thing like that, you won't grow old. Heart and all....Rural, little traffic, windows closed and it should be quiet....well, close the windows and that's fine. That is more than enough. Triple glazing, that insulates and absorbs a lot. Shade helps against heat, so not too little roof overhang. And in the south, not too much glass.

If you worry about every little thing like that, you won’t last long. Heart and all.... Rural, little traffic, windows closed and it should be quiet.... well, take the windows and that’s it. That’s more than enough. Triple glazing, that insulates and absorbs enormously. Against heat, shade helps, so don’t have too little roof overhang. And in the south, don’t go overboard with glass.

That was actually my first thought too, but as a layperson I prefer to ask. At the moment I’m leaning towards the mentioned windows in the RC2 variant for the ground floor and without RC2 for the upper floor. It was definitely important for me to know that you can’t install windows that insulate too well.
