Masonry from Ytong 24 or 30 for single-family house?

Oh, I see... The surcharge for the 36.5 size would have been at least 10,000 euros. It involves more than just the stone itself (e.g. a larger base plate to maintain the same living area, then of course a slightly larger roof, etc.)

TundC also wants to manage all that with 24 cm? It's unclear how that works. Ask them, the 30 cm is a good choice, I tell you.

So with 30 cm aerated concrete you achieve "Kfw 60" but with 24 cm one may doubt that the Energy Saving Ordinance is being met? I see. Insulation thicknesses or wall thickness for insulation purposes are calculated and nothing else.

Nothing like that. It was calculated by an engineer from Flensburg. I have the calculation.

And the 24cm from TuC are then probably made up? Or do they perhaps follow the same calculation method?

the point is that you cannot on the one hand question whether 24cm Y-ton is even sufficient for the energy saving ordinance, and on the other hand claim that your additional 6cm are enough for an imaginary KfW60.

Burglary protection? Yes, you can break the wall if you drive in there with a Unimog.

I think he means: windows screwed into the y-ton can be completely pushed in along with the frame and screws, making less noise than breaking the glass.
