Due to the different behavior of the building materials (settling, etc.) I would personally recommend a uniform building material. I myself have also planned Poroton for the interior walls.
Poroton or Ytong - insulation values, etc.?

So, in summary, Poroton is also good for a pleasant indoor climate! But is it generally more labor-intensive to work with?

Hello,
Since quite a bit has already been written here about Poroton, I will focus more closely on the building material aerated concrete.
Poroton
Masonry bricks (trade name: Poroton) consist of clay, loam, sand, and foaming agents (e.g. sawdust). The bricks are first dried at temperatures below 100°C and then fired at about 1000°C.
Poroton bricks can be laid either as block bricks with lightweight mortar or as plan bricks with thin-bed mortar. Since the thick-bed process with lightweight mortar has some disadvantages, only plan bricks should be used nowadays.
For several years, Poroton bricks with perlite filling have been on the market. Compared to conventional hollow bricks, these offer better thermal insulation as well as higher fire and sound protection.
Walls made from hollow bricks without filling have higher thermal conductivity in the vertical direction, especially when laid with conventional thin-bed mortar that does not reliably seal the holes (convection!).
Aerated concrete
Aerated concrete is made from sand, lime, cement, water, and aluminum powder (foaming agent). After cutting, the blanks are cured under steam at 200 °C.
Aerated concrete (plan) stones are also processed with thin-bed mortar. The stones are easy to work with (sawing) and are valued by many DIY builders.
With a wall thickness of 36.5 cm, optimal conditions are thus provided for the construction of an energy-saving house. At the same time, two other requirements that play an important role when building a modern structure alongside thermal insulation can be met with this building material: airtightness and minimization of thermal bridges.
This is due to the homogeneous structure of the aerated concrete building material, which has the same thermal properties in all directions. Material-related thermal bridges, which always occur when two materials with different thermal behavior meet, are thus easily avoided.
In addition, the individual components of the building system are uniformly coordinated with each other and feature simple, reliably executable connection details. This prevents the formation of installation-related thermal bridges from the outset.
The precise manufacturing of the various components also enables exact processing. The individual components of the building system can be joined absolutely airtight and windproof. This ensures that no warm indoor air escapes to the outside through open joints and defects.
In addition to high thermal insulation and an airtight building envelope, the building material aerated concrete also offers good heat storage. This way, living areas are protected from cooling down in winter and from excessive heating in summer. The result is a consistently pleasant warm surface temperature that ensures a healthy and balanced indoor climate throughout the year.
Kind regards
Which stone would you recommend to achieve good insulation values?

Best to stick with one building material, so in my case aerated concrete or Poroton! Limestone sandbrick is off the table with that!
The properties of aerated concrete, like the very important thermal insulation, are again a point in favor of Ytong for me!

Hello!
What should the walls be able to do? The thermal insulation is provided by the core insulation or the ETICS (except in the case of monolithic construction).
The insulation value of the mineral exterior walls is secondary, that of the interior walls even less important!
What matters are soundproofing, statics, and fastening possibilities; so: calcium silicate brick, at least for the entire interior area!
Anyone who has ever tried to attach something to bricks or aerated concrete (tension rods for curtains, wall cabinets, etc.) knows why.
Regards, Tom.

Hi!
Not quite. The note about a uniform building material is not wrong. It is also better to pay for the house immediately in cash. Sometimes you have to choose the lesser evil.
Otherwise: If it is not going to be a passive house, exterior walls made of KS will probably work fine – and everyone will be happy.
The note about the breathable brick wall is b....nonsense; try breathing through 2 cm of plaster! All of the mentioned building materials are vapor permeable as long as you don’t install WDVS.
If bricks are to be used after all: The sockets will be generously plastered in.
You will find supporters of every construction method. I personally love KS. Brick and aerated concrete are still okay. Only slats and foil (timber frame construction) I find ridiculous.
