ᐅ Is aerated concrete strong enough to support kitchen cabinets?

Hello, I am planning to build a wall and am considering whether aerated concrete (YTONG) is a good choice. Here is the situation – I have a fairly large living room (35 square meters (377 square feet)) where the kitchen will also be located. However, I want to separate the kitchen with a wall (shown in yellow in the picture) to prevent cooking smells from spreading directly into the living room.

In addition, I would like to find some kind of "glass solution" (shown in green in the picture) to allow some sunlight to enter the kitchen. I need some ideas for this, as a simple window would look odd.

My question is – is a wall made of aerated concrete suitable for this? Is it strong enough to support the upper kitchen cabinets? If yes, how thick should the wall be?

Please excuse my poor German skills and thank you very much in advance!

There is little to comment on regarding your design. The plan for the entire floor would be needed.

There are fasteners available for almost every type of wall, including Ytong (aerated concrete) walls.

Definitely, it all depends on the anchors. In aerated concrete PP4 (standard for interior walls), universal anchors hold quite well. However, building and plastering a wall in drywall or timber stud, double-layered and possibly reinforced, would probably be easier.

Yes, with the right anchors this is not a problem. Many houses are built entirely from aerated concrete. Whether this is the best solution for your project, I cannot judge.

A colleague at work got the Ytong driving tool and said his kitchen cabinets hold with "normal" anchors using it. I didn’t know this before either, but it makes sense because the aerated concrete is compacted all around with this tool.

Usually, the hole is drilled about 2mm smaller, and then the plug is driven in. This is done to ensure the hole is precise and not too large.

If anything is compressed, it’s just the 1mm that is “displaced.”

I’d say no kitchen installer really checks whether the wall is made from aerated concrete PP4, PP2, bulk density class 0.5, 0.4, 0.35, or anything else. They just use a plug suitable for aerated concrete and that’s it. Even our site manager said when I asked, “Don’t buy the cheapest one at the hardware store, then it will fit.” SX, UX, that kind of thing.

The Duopower 10x80 plug from Fischer can carry 0.3 kN in PP2 aerated concrete. This is the typical thermally insulating exterior wall. So, for a kitchen cabinet, it’s better to drill 4 holes instead of 2.

If anyone thinks this Poroton stuff is vastly superior… no. Hollow brick holds 0.4 kN. About 10kg more load per hole.

In PP4 aerated concrete, it’s already 1.1 kN per 10x80 plug.
