Hello building experts,
It looks like construction can start soon. I was convinced by the regional TuC partner regarding the overall concept because of the monolithic construction method.
In the "basic package," the masonry is made from 24cm (9.5 inches) Ytong blocks. Does anyone have practical experience with thermal and sound insulation? The residential location is very quiet, traffic-calmed, and has almost no through traffic.
Alternatively, I am considering a build with 30cm (12 inches) blocks; I still need to find out the additional cost.
Best regards,
Ruska

24cm Ytong as an exterior wall? Considering that at specific points, for external electrical boxes and water pipes (shower, bathtub, etc.), 5cm (2 inches) will be chiseled out, that would leave only 19cm (7.5 inches) remaining.
There are also some plumbing companies that, without hesitation, install the supply and exhaust air ducts of the controlled residential ventilation system inside the exterior wall, which means that with a 24cm (9.5 inches) wall, there might only be 5cm (2 inches) left.
Also, the increase from 24cm (9.5 inches) to 30cm (12 inches) is crazy expensive (10,000 euros), which can’t be right since the actual difference should be limited!

We built with 42.5cm (17 inches) Ytong blocks and are satisfied with them. Of course, you can’t expect much in terms of sound insulation.
Regards Is that a typo, or do you really mean 42.5cm (17 inches)? I wouldn’t have expected compromises regarding sound insulation there.

So, we also built our garage with monolithic 24 ytong blocks... but for a single-family house? My minimum would be 36 cm (14 inches)... We ourselves have 17.5 cm (7 inches) calcium silicate blocks (20 / 2.0) plus 14 cm (5.5 inches) external thermal insulation composite system (ETICS) with a lambda value of 0.035. I’m not sure about the energy saving regulation standard, as we didn’t build according to any particular standard. In any case, we are satisfied and have no issues with sound insulation...
24 cm (9.5 inches) really sounds like the "cheapest" option...
