ᐅ Y-Tong (aerated concrete) – a quality building material? (Sound insulation!)

Dear Forum,
Our developer plans to use "Ytong PPW2 d = 36.5 cm (14.4 inches) for the exterior walls according to the scope of work. Inside, 17.5 cm (6.9 inches). On the outside, a 3 mm (0.1 inch) mineral-based lightweight plaster will be applied. To me, this seems somewhat minimal compared to the insulation and materials others are using.
We are wondering if the thermal insulation requirements are met without additional insulation? And what about mold and ventilation? A air-to-water heat pump with underfloor heating is planned.
What worries us even more is the soundproofing, since we have a cobblestone street right outside. A friend who is an engineer told me yesterday that Ytong has "poor sound insulation properties."
So even triple-glazed windows with enhanced soundproofing probably won’t help much? [B] I would appreciate honest clarification and possibly some alternative suggestions. We are not experts and I don’t want to hear every car! Some friends of ours build with calcium silicate blocks and are very satisfied. Their father is an architect and swears by them.
Many thanks and best regards! We would be lost without you!

I’m bringing this thread up again. I spoke with a construction company today, and they recommended Liaplan. I’m reluctant to use Ytong, but Liaplan seems to combine all the advantages. Has anyone had experience with it? You’ll probably find more experiences here if you search the forum for Liaplan as well as Liapor or even expanded clay aggregate. I’m familiar with aerated concrete, even from my own experience with my factory building, and I have no reservations about it. I personally live in pumice, which is basically the third related material. If your builder has experience working with Liaplan, go for it. The block itself is absolutely fine, and in my opinion, the best choice is always the one the builder knows best how to work with.
