Single-family house - Right choice Poroton?

Sorry, but you are only throwing points into the room that are either wrong or without argument. Please stay out of my thread. Thank you for your understanding.

Best regards

regarding your question in the thread: my opinion NO. Poroton and ETICS is not the right choice in my view. if ETICS then 17.5 cm KS, if only for sound insulation reasons.

I don't think the 17.5 Poroton is pressure-resistant enough for a load-bearing wall. besides that, I would only rely on KS with ETICS. the interior walls can then be done in 11.5 and still have better static, heat storage and sound insulating properties than Poroton and you can also better fix things to the wall.

the construction companies I know and have worked with in the past processed the stone I wanted. they may have had worse conditions when purchasing but they were always able to process everything.

therefore if absolutely Poroton+ETICS then 24 cm but why can't bu#1 then??? everything somehow strange....

But as you notice, there are now two of us who share a similar opinion.

What is wrong with the fact that every stone has thermal insulation properties? What is wrong with the fact that you will get annoyed every time you want to make something hold in the wall?

The stone is simply not the best choice for your construction project.

And no, I have no understanding that you apparently (still) have no idea, but portray other people's statements as false without proving it.

0.18 W/mK for the T18 is a joke and therefore I do not speak here of the thermal conductivity of the Poroton T18. For me, a stone has thermal conductivity when it can also serve as a replacement for an ETICS. Whether filled Poroton stones are sensible or not, we will leave aside for now. It does not matter if you are two or three! You have not helped at all so far. If I ask whether to buy a green or yellow car and you answer red, that is simply useless. That a T18 with 17.5 cm is not pressure resistant enough for a single-family house is not true. And I never said that contractor #1 does not offer any aerated concrete. He offers Ytong or POROTON directly as options; sure, you can get anything else as well. If I am supposed to consider aerated concrete, which one would you suggest? Best regards

If I compare a sand-lime brick (bulk density class 2.2) with the Poroton T18 each at 17.5cm, I do not see any significant advantage. See attachment.

Maybe you can enlighten me.

Best regards

Only soundproofing would occur to me immediately. However, our property is located on a dead-end street and this one in a 30 km/h traffic zone. The interior walls might need to be considered here. I will put noise from outside aside for now due to the above argument.
