Good morning everyone!
My husband and I (both rather paper people) are going to build a fairly large semi-detached house and are wading through the jungle of possibilities. We want a solid construction and have now spoken with various providers. There were the following options regarding bricks: aerated concrete, Poroton, and expanded clay (prefabricated), all in 36.5 and monolithic construction. Of course, for every consultant, their own building material is the only true and right one, so I would be interested in your assessment and experience.
"Actually," we would rather not want to build with aerated concrete/Ytong, as our naive assessment regarding moisture absorption (sponge effect) during construction and later during drying is rather negative. However, I can quite understand the argument of easy workability.
Poroton would be our "favorite," but I have the impression that many companies really resist using it because of a lot of waste, much lost during transport, "you don't notice a difference," etc. Of course, there is again the branching into filled and unfilled.
And then there is expanded clay. Our "new favorite with a question mark." Very interesting because somehow it is the best of both worlds, dry from the factory, fast, even cheaper. BUT if it’s so great, why don’t many more people build with it and there are relatively few providers? That makes us skeptical. I have already googled and read a lot that there are often cracks and that the insulation properties are not the best compared to Poroton. We were told here that a 36.5 Poroton unfilled is comparable in properties to a 42 expanded clay.
We can’t make sense of the jungle of U-values, lambda, etc. Can you support us? BTW: insulation would be more important to us than soundproofing.
Thank you all!
