Poroton or lime sand stone

Aerated concrete is not the same as Poroton

Hehe yeah, my mind was elsewhere. But the question still stands.

Statically, this was not necessary, but I wanted it that way. a) because of soundproofing, I have the office on the 1st floor, and b) because of heat storage. I have an open kitchen/dining/living area, and there is a masonry heater inside that is supposed to nicely warm the walls, and the more mass, the longer the heat lasts. I'll attach a picture of my floor plan, you can see it clearly there.

Are there also bad experiences with Poroton? Our general contractor usually builds with it and since he is specialized in it, we would like to keep him.

An alternative provider strongly advised against it. I don't judge because he builds and wants to sell with sand-lime brick, but he said, for example, that you cannot properly get a nail into the wall and all wall mountings are very difficult. It must also be ensured that the craftsmen do not throw cigarette butts etc. into the holes of the Poroton bricks during construction and that no rainwater remains inside.

Oh yes, above all "etc." should definitely not be bricked into the holes. Little notes with satanic verses, for example, because those are loudly read aloud by little goblins on full moon nights. Lord, please throw some brains down from heaven, all the stupid things that are told about stones. The red color in the bricks comes from paprika, which is why you always have to sneeze in such houses.

There is someone for every stone who can tell you why it is devil’s stuff, useless, can’t be good, and should best be banned.

Our general contractor usually builds with it, and since he specializes in it, we would like to stick with him.

And that is exactly what matters: that the installer knows his stuff well.

You can calmly place a Poroton house ecumenically next to a Ytong neighbor’s house; they don’t quarrel. KS is just simply different, but they are all materials that are perfectly suitable for building walls.

Soundproofing would be the most important thing to me when choosing the stone, and apparently Kalksandstein is currently the "best." Of course, an external [WDVS] is then necessary, but I wouldn't care about that. I have Poroton in the garage, and yes, it is not so easy to get a plug into the wall. Everything that requires larger holes needs special plugs for Poroton.
