H+H multi-slab load-bearing 100 mm?!

[Kallebo]

I read in a thread that you shouldn't build 100 mm thick load-bearing walls higher than 2400 mm as they may risk becoming unstable.

We want part of our hearth wall in our house to be made of aerated concrete, and I have set my sights on the Multiplattan from H+H. We want it to be in a relatively massive and non-combustible material to be able to place a tile stove directly against it. It will then heat the wall and thereby spread some warmth in our house.

The problem is that we want to make it 2800 high. Does it work with the 100 mm blocks, or do you think we need to go up to 150 mm for stability?

I have emailed H+H without getting a response.

Isn't 100mm rather weak for a heart wall from the very start? Is there a big price difference between 150 and 100?

without knowing, I would also say that 100 is flimsy for a heart wall, what if you then cut a little electricity etc then there's not much left... surely there are those who know better but 150 can hardly hurt..

The price difference doesn't matter. It's the wall thickness I want to keep down, we're building a small house.... But five centimeters might not make much of a difference..

I'll have to call H+H and check tomorrow.

Thanks for your thoughts.
