ᐅ Is a 30 cm aerated concrete (e.g., autoclaved aerated concrete) wall sufficient?

Especially since [...] prices don’t stay the same and in the scale of house construction they rise faster than one can save against them, and, and, and... [...] If you sign a contract now, you’ll move in around your mid-40s and be finished by your late 50s... I would either start now or not at all.

That’s why my motto is "Build now," because rising prices are the only certainty the future holds. Anyone who invests their creditworthiness in reasonable real estate — and is willing to downsize again if the kids need space elsewhere — will live better than someone watching their purchasing power shrink while waiting for building prices to fall "after the bark beetle," "after Corona," "after Putin," or after whatever else.

the last 20% of Pareto isn’t needed for a normal person’s house.

Those (if you understand Pareto and percentage calculations) 400% extra costs for a 25% gain are simply unaffordable for an average person.

The masonry block is only one part of the thermal insulation puzzle. And with KfW40 subsidies, it still ends up more expensive than the Building Energy Act without subsidies.

Preemptive obedience to tomorrow’s regulations or avant-gardism in energetic woke-ness is a patronage only the well-off can afford on their own. The legally taxed citizen should abandon any naive hopes that powerful elites concentrate subsidies particularly in lower wealth classes. The devil never defecates on the smallest heap. If subsidies systematically overcompensated additional investments, they would be illegal under German tax and social law.

In the end, the masonry block doesn’t matter. All houses hold up with it, and you won’t recoup the price difference between 42.5 Ytong and Poroton T9 through heating cost savings during your lifetime, much less make a profit.

Furthermore, based on my extensive and deep knowledge of various building materials, there is especially one type of block you will NOT find on the market: the philosopher’s stone.

Until now, I always thought that Poroton TP had a slight advantage in sound insulation compared to aerated concrete. However, according to the datasheets, this doesn’t seem to be the case at all. [...] Are these specifications really accurate? Everywhere I read that Poroton provides better sound insulation.

Are you still stuck searching for the “Philosopher’s Stone”? Don’t you have better things to do than watch prices rise while playing data sheet quartets?
You can spot amateurs by how they get lost in endless trivial details...
While Villabajo is still chasing the top-rated brick, Villariba already has the foundation earthing in place.

No, I signed long ago and already have the building permit / planning permission plus KfW funding approved. Now we just have to choose between Poroton and aerated concrete :-)
