ᐅ Masonry using Ytong blocks, 24 cm or 30 cm thick, for a single-family house?

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

I think he means: windows screwed into y-ton can be pushed in completely along with the frame and screws, producing less noise than breaking the glass.

You could also just pick through the wall with a screwdriver.

Guys, this is getting crazy now, no one pushes a mounted window out of a Ytong wall...

And I also understand that t and c calculate this somehow, but I wonder how? Because the Team massiv can’t manage it and always does 24 cm (10 inches) with ETICS.

Then take a look at the effort required to achieve genuine RC2 security with a 24cm (9.5 inches) Ytong wall: the reveal areas are left open during masonry work and then filled with concrete. This allows for anchors and screws to be used. Otherwise, the entire window including the frame can be pried open. This is not a joke.

In my construction specifications from Team Massiv, it states 17 cm (6.7 inches) aerated concrete (H+H) plus ETICS. Where did you get the info about 24 cm (9.5 inches)? Could it make a difference whether it’s Ytong or H+H?

Actually, I chose TuC because I didn’t want plastic insulation. Otherwise, Team was also very appealing.

Only 17mm (0.7 inches)? I thought they always use 24mm (0.9 inches) as well.
