Window offers like day and night

this frame is called "Anschlag".

Oh, I see.

The measure of this window replacement at the current time seems to me to be sheer nonsense; these windows would economically be thrown out to the same extent.

That would be the fifth step before the first, and such blind actionism has never been fiscally sensible.

Not knowing about some things yourself is no shame. Many seekers of advice then fall into the hands of charlatans, in your case it is probably just a bungler, so at least not the worst possible luck. But it will still be enough to waste a lot of money.

With the attitude "then we'll first do things we somewhat understand, then they’re already done, and the whole investment doesn’t pile up in a single tax year," you are in good company – but that doesn’t make it any better.

If I remember correctly, you once spoke of ceiling slabs that might still be replaced; and the usage concept still hasn’t been touched. I can hardly imagine a worse time than now to supposedly check off the window issue already – even though I really shouldn’t say that, as I myself once bought my first car radio even before the driving test – but that is a completely different financial dimension.

What, in my opinion, is not outright nonsense, however, is the insulation of the reveal surfaces, because of course they belong to the interface of the exterior walls. Basically, my thought there would also be a more effective insulating material relative to the general wall surface in a slimmer design; but NOT NOW.

The measure at the current time is about as sensible as installing downpipes before having thought about where the bathrooms are supposed to go.

I know, I know Thies. There are the owners with decision-making power and those who are only allowed to give good advice. We both belong to the latter. I have already tried to talk them out of the window story. On the other hand, it is understandable: There are now 20K euros that either end up at the tax office or as a new window in the house, and that by March.

On the other hand, it is understandable:

Yes, sure. Your relatives are probably still the generation of trained GDR citizens. We don't yet know whether it's deer or hares that will come in front of our rifles (and when); but lingonberries are on sale this week, and we need them for the sauce anyway, so they are being picked up just now. Got it

No, there are new windows, for which one has to explain to the tax office why they have to be removed again in two years - partly because the window openings will be changed again, and partly because they suffered during the construction phase.

But I know Starsinn, from fathers-in-law twice over, over 70 and Westphalian *smile*

Well, apparently you never really learned to be a genuine GDR citizen after all. If there are lingonberries, all that are there will be bought and surplus quantities preserved. And if necessary, they will then be spread on bread until strawberries are available, and so on.

We recently rummaged through the old GDR stock for the sewing machine department. If you saw that... Everything pure gold worth - but only in GDR times. Now it’s all junk. It breaks your heart.

No, there are new windows, for which you have to explain to the tax office why they have to be replaced already after two years – partly because window openings are changed again, and partly because they suffered damage during the construction phase.

Yes, something like that. But we hope it won’t be quite that bad.

But we hope that it won't be that bad.

But it will. You can see for yourself, there's a domino effect: the windows are connected with the reveal insulation (which doesn't necessarily have to be done at the same time, but must be designed accordingly). And then things turn out differently and the windows either look frameless from the outside (with divisions or muntins especially awkward!) or you cautiously end up making them "too small." Dilemmas are honey for philosophers, but vinegar for practitioners.
