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!

Why wouldn't that make sense? Unless you are building in a very noisy location, the main issue with the exterior wall is thermal insulation, and with interior walls, it is soundproofing. So everything is done correctly. Around here, this is the typical construction method used by higher-end general contractors (often still with brick cladding, to be fair).
Our shell construction has just been completed. On the outside, we used Ytong blocks, and inside, calcium silicate bricks. The bottom layer of the interior walls is also Ytong.
Insulation was then attached to the external Ytong using fasteners, and this was followed by a brick veneer.
This construction method is quite common in the North and combines good thermal insulation on the outside with soundproofing on the inside.

Around here, this is the common construction method used by higher-quality general contractors (often still with brick cladding, admittedly).Building in a quiet suburban area eliminates noise issues. We shouldn’t have any problems with that then.

ETICS is basically hazardous waste, and I wouldn’t want to wrap my house in that. Why not use bricks, preferably insulated?Anyone who wants to avoid using hazardous materials should also consistently avoid paints and coatings, sealants, or plastics. This includes oil tanks, PVC pipes, electrical cables, as well as wood components treated with preservatives and paint, since all of these are classified as hazardous waste. Even bricks with wallpaper still attached or empty cans of expanding foam often fall into this category.
