Hello everyone,
Our architects and the structural engineer have specified calcium silicate blocks for the exterior and load-bearing interior walls.
Now we have received a shell construction quote using pumice blocks (according to structural requirements).
Therefore, I would like to discuss the topic of calcium silicate blocks versus pumice blocks with you. What are the advantages and disadvantages of each type of block from your point of view? Who has experience?
Just to clarify: an external thermal insulation composite system (ETICS) will be applied to the masonry.
Thank you very much!

However, you have to accept external thermal insulation composite systems (ETICS), and that adds to the cost. Another question is, what speaks against using clay brick? Although it is more expensive than calcium silicate brick, if you think that calcium silicate brick definitely requires ETICS, then the price difference might no longer be significant.

Some say use what your shell builder can work with best, but I wouldn’t choose a shell builder who installs aerated concrete. My mantra is "use the material the builder knows," and your approach "avoid builders who use what you consider the wrong material" are two sides of the same coin.

Pumice, also called Ytong or aerated concrete Ouch. Pumice is not aerated concrete.

Porous materials are not nonsense; they are justified everywhere sound insulation is not important. We live in a single-family home area at the end of a cul-de-sac. Why would we need special soundproofing? That’s why we don’t have any polystyrene panels on the walls with our artificial pumice Ytong blocks. And yet, the house is warm. For fixing items with plugs, standard wall anchors work fine—nothing special is needed. You drill holes with steel drill bits, which make clean, round holes in the soft stone. The anchor then fits tightly and grips very securely.

In my view, it’s the same nonsense.You can think of it as crap if you want, but it’s not the same thing. Tofu isn’t celery schnitzel just because hardcore meat lovers dislike both.https://www.instagram.com/11antgmxde/

Load-bearing masonry with external thermal insulation composite system (ETICS) on top.
Pumice blocks are about 2% cheaper...
