The formation of cracks will probably always depend on the execution, drying, etc., however, I can say that an acquaintance who built with an insulating stone (don’t ask me exactly which one) has many settlement cracks in the interior plaster, whereas after 3 years we have not had a single one. Whether this has something to do with the stone might possibly be explained by an expert, but all houses built with calcium silicate bricks and ETICS were plastered completely right away, that is, with a fine render. A neighbor who built with Ytong said that with him, one has to wait to apply the fine render so that no cracks appear. As said, it is possible that the soft Styrofoam helps prevent cracks here; in any case, we have none. That could then possibly save money as the scaffolding would only need to be set up once. Why should calcium silicate brick walls dry more slowly? These are huge blocks that are only bonded with a thin layer of adhesive. The water content in the wall is therefore negligible compared to the plaster / screed. Also, better indoor climate is often advertised precisely because the stone can absorb and also store more heat, meaning fluctuations are rather lower.
