We had originally planned to build our new house with T9 Poroton bricks 36.5cm, this would also have been approved, and the structural/winter insulation calculations would have been created accordingly.
Now we have received the suggestion to build the house with aerated concrete blocks Ytong.
Who even makes such a suggestion – some pub talker who enjoys unsettling colleagues with his baker’s dozen knowledge during lunch breaks?
There is no philosopher’s stone and no devil’s stone. Absolutely speaking, there is no stone with properties that one must warn against (or consider oneself lucky to have found Columbus’s egg). However, relatively speaking, every stone is “bad” with which the builder has little (or less) experience. Details in other properties lead to having to do connections to other components differently than what has been practiced thousands of times, and with that, one has bought the somewhere-after-the-decimal-point “better” stone at the cost that less practiced processing results in later defects. In this respect, changing the stone often also involves changing the builder. What answer does your smart aleck have to that?
Be glad to have received the building permit, and don’t let yourself be distracted now by well-meaning interference.
