Single-family house - Right choice Poroton?

Then why don't you respond to my criticism . I tried to communicate with you and weigh the pros and cons. I am not (yet) set in my decision. But if you bring up arguments and advantages that are not relevant according to the wall construction values I mentioned earlier as per "u-wert.XXX," then I wonder how we are supposed to communicate sensibly here.

So let's leave it at that, all the best to you.

@robi: You input some values into an online calculator and simply misinterpret the results. Of course, there is hardly any difference in the U-value between KS and Poroton when you slap external thermal insulation on, since the surface temperature between the building materials is high anyway and thus there is no temperature difference between the interior and the outside wall surface. The summer heat protection is better with massive building materials on the inside, which is why KS simply makes more sense with an ETICS. If you want to use Poroton, you can save the ETICS with a slightly thicker exterior wall.

That's exactly what I've been saying/writing the whole time! Due to the WALL STRUCTURE, it hardly matters whether KS or Poroton is used. Only if you look at the brick alone.

Some values? What exactly do you mean by that or how do you come to that conclusion? The values correspond to the specifications of the BU. Therefore, I don't understand your statement!

As I have mentioned several times, I am not yet decided whether to use Poroton or KS. However, I have basically excluded a Poroton with e.g. 36cm and a filling, as I have read a lot in this forum that the fillings "come out". In addition, the shell construction with this brick probably causes additional costs, right?

Now I wonder if only 17.5cm are a disadvantage for us and if so, which one(s)?

Regarding the color of your car: No! Everything else can surely be told to you by your online calculator.

I meant to say that if an ETICS is desired, massive components, e.g. KS, have building physics advantages. Without ETICS or core insulation, the stone of the external wall should have the appropriate thermal insulation properties. I do not consider a highly insulating stone with ETICS on top to be sensible.

For the builder, of course, the lightweight stone can have advantages because it is so easy to work with.

By the values I mean the values from the U-value calculator, which must be interpreted correctly.

I do not consider a highly insulating stone combined with ETICS to be sensible.

Absolutely.
