Exterior wall for KFW 40 (+) with or without ETICS?

I find it hard to imagine that stones will just end up in the rubble dump in 80 or 100 years.

I wonder what will eventually be done with these filled bricks. Are they mineral-filled? Can they be disposed of as easily as regular stones?

Allegedly, the first plastic ETICS has been sticking to houses without problems for 50 years.

Not without problems everywhere. On renovated houses, you sometimes see these 5cm large spots. Those are the disc anchors for fastening. If the entire facade isn't painted every few years, it looks really bad. Nowadays, the anchors are recessed further and then covered again with a cap made of insulation material, or in new constructions there are no anchors at all, if allowed according to the manufacturer's specifications.

ETICS made of Neopor/plastic only burns when exposed to air. So windows explode, plaster peels off, flames break through, after about 20 minutes the facade is burning.

When I walk down my street, I see a house where plaster above the ETICS has peeled off and open spots are visible in the window area. Also, some edge areas at the transition to the next row house neighbor have only been half-heartedly plastered. This reminds me of a story how my previous owner tried to burn shrubs directly at the facade. Rarely, very unlikely individual cases chain together...

Allegedly special anchors and screws work for lamps, mailboxes, and such. Ex-neighbor is not satisfied.
During construction, firmer material can be attached at the lamp outlet.

Correct, but with mineral wool you have to drill all the way into the wall. Anchors do not hold at all in the insulation wool. Anyone with two left hands will curse hard trying to screw anything onto the facade.

We chose, for example, a rafter insulation and the

May I ask you what additional cost you paid for the rafter insulation (a percentage is sufficient).

May I ask what surcharge you paid for the rafter insulation (a percentage is sufficient).

Unfortunately, I can't tell you that, he calculated one thing out and another in, and we supply the material ourselves, so it's hard to say. According to his general statement, there is no massive difference, and we wanted it that way anyway. I don't have individual line items. Judging by what I sometimes read here, it will depend on how your provider calculates it and whether they are willing to do it. Ours is willing to build the house this way or sometimes slightly off-standard, you can tell, and apparently he also calculates it fairly, as far as I can see/hope... o_O In any case, you can then properly add PUR/PIR insulation material with the best WLG values from the outside, and at times the energy consultant even calculated with 30 cm, which was then relativized by other measures. That's why I say it's a package of measures, depending on several parameters, such as additional costs from my chosen company, my own design wishes, etc. Since we also decided on a wooden facade, there is also insulation underneath it, which allows us to achieve this Kfw standard. But that was more of a process that was not initially intended, as we originally wanted to build according to the Energy Saving Ordinance; through the existing, affordable options for redesign, we ended up where there was not far to Kfw40Plus, and the energy consultant also somewhat motivated us to implement that. In that sense, it was more of a "from the frying pan into the fire" outcome.

I really hope for you that you are not planning roof insulation with PUR without special measures. For good reason, this is no longer state of the art, since it provides no sound insulation whatsoever. Otherwise, you can already get ready to sue your architect like many before you... But then please write that you are combining it with insulation between the rafters..

I really hope for you that you are not planning an over-rafter insulation with PUR without special measures. For good reason, this is no longer state of the art, as it offers no sound insulation whatsoever. Otherwise, you can already start suing your architect like many others before you... But then please write that you are combining it with between-rafter insulation..

What sources are there that say this is no longer state of the art? Which lawsuits? What do you mean by special measures? Sound insulation from outside? Between-rafter insulation is not planned, but a visible roof truss. Any concrete information about this is welcome, always send it.

Solid construction is also just one method of construction, regardless of where the insulation is located. Ecologically and in terms of energy efficiency, a timber frame construction is an alternative even in multi-family housing. Particularly in metropolitan areas, which for us is the Rhine-Main area, every square meter of living space counts in planning due to land prices. Often, additional living space cannot be created otherwise on existing buildings due to the weight. Fire protection as well as sound insulation (airport) can be solved today. Regarding the lifespan, I consider the craftsmanship to be very important. Often, I only accept a trade after 2-3 attempts during construction management. Special construction methods such as fully round walls are completely out of the question.
