KFW40 or better in solid construction, possible without additional insulation?

Hello,

I was actually always set on a timber frame construction for the future house. However, now I want to reconsider solid construction because it also has its advantages.
However, I would prefer this without additional external insulation, as that would be redundant, and the insulation doesn’t have as high a lifespan as the masonry itself.
Poroton seems the most appealing to me at first.

But is that even possible? Are there bricks (or other solid building blocks) that alone meet the KFW40 standard or maybe even better?

Does anyone have experience with that?
Has anyone ever built something like this?

I am open to discussion if you think additional insulation makes sense. But no "Styropor" goes on the outside wall; if anything, it would be something else.

What I would like to avoid are comments suggesting that a lower energy standard is sufficient. Nothing worse than KFW40 will be built.

Thanks in advance for your input.

Best regards
Specki

Are you planning a basement?

If yes, then you don’t need to read any further. With a basement, I don't see Kfw 40 and bricks without insulation.

If no, then probably only with filled 42cm bricks.

In monolithic construction, it becomes difficult. The wall becomes very thick and the bricks are expensive. If it should not be EPS, how about two-shell sand-lime bricks with mineral wool in between? Outer shell also sand-lime bricks with plaster or as clinker.

No, no basement planned. Only insulated slab.

If double-shell with mineral wool in between, I have the risk again that the mineral wool will eventually not hold. No idea, if somehow moisture gets in, or pests.

Maybe I also have the wrong idea. And a well-planned ventilated facade insulation made of mineral wool or a natural insulation material also easily lasts 80 to 100 years?

Yes, that easily lasts longer than you. Monolith also works.
