Good morning,
Yesterday we had a conversation with a general contractor. We mentioned that we would like to have a 365mm (14.4 inches) wall (Ytong or Poroton). The immediate response was: he doesn’t think much of that; 240mm (9.4 inches) with 120mm (4.7 inches) of Styrofoam insulation is much better than the 365mm wall.
He also said that the energy efficiency rating would drop from A (+) to D?!
I’m starting to not know what to believe anymore... everyone says something different.
What do the experts here say?
Thanks in advance.
PS: I also asked, because I had read and heard somewhere that aerated concrete (Porenbeton) is easier to work with than Poroton. The response was that this is complete nonsense... oops.
Best regards,
Steven

This is just to illustrate that comparing two bricks solely based on the material type is the wrong approach. Both options include different models.
Similarly, it makes no sense to compare material prices found online. This will not give you any indication of the offers you receive from contractors. For the same U-values, aerated concrete (AAC) can be cheaper in one case, and clay blocks (Poroton) in another.
