It has better thermal mass, which helps even out temperature fluctuations, and provides improved sound insulation. The insulation is handled by the external thermal insulation composite system (ETICS) anyway.

Margarine or butter?
Regards, BauexperteI prefer to use margarine^^
In my opinion, both building materials are fine, right?
It's probably just a matter of personal preference whether you choose Poroton or calcium silicate blocks.
Personally, we also tend to lean towards calcium silicate blocks.

Well, we are also very satisfied with the sand-lime brick, especially since you don’t need special anchors when you want to fix something heavy, and the sound insulation is noticeably better.
Additionally, you sometimes have narrower interior walls, which CAN result in extra living space.

We are facing the same question. We are planning to build a semi-detached house with approximately 165 sqm (1,780 sq ft) of living space, two full floors, and a full basement, which will be attached to another house we own from the 1950s. Based on our initial research, we prefer a monolithic construction method using Poroton clay blocks. The reasons for this preference are the supposedly better indoor climate, no need for external thermal insulation composite systems (ETICS / facade insulation), and especially a lower risk of mold growth due to shorter drying times.
Our architect is not convinced by this approach and wants to build the house using sand-lime bricks with ETICS because of higher load-bearing capacity (reduced risk of cracking) and fewer issues with material transitions, as thermal bridges would be eliminated by the ETICS. At the same time, he suggests building the basement with Poroton.
Other arguments in favor of sand-lime bricks, such as thinner wall thickness or sound insulation, are less relevant given the size of the plot and the residential area.
Additional research and discussions with construction contractors have not helped clarify which option is actually better. We are quite uncertain and would appreciate your input.
