Basic structure in leca with good insulation value?

[Draven]

We are going to build our hillside house with a foundation frame in Isoleca blocks, and I'm wondering if 0.43 is a good/suitable value. Leca also has one at 0.29 called Ergoterm. But this is awfully much more expensive.

We built our basement in Lammi blocks, and their U-value is 0.25 W/m²k. We initially considered leca, but concluded that leca with insulation would only be around 10-20,000 SEK cheaper. On the other hand, this resulted in robust insulated concrete walls that can hold almost anything.

Ok. Thanks
I assume you don't plan to frame and insulate the interior walls when it comes to the walls with lammi blocks?
I will insulate on the isoleca blocks.

No, we are not thinking of that, one of the reasons we chose it was to avoid doing it with lammiblocks.

We will be building with regular non-insulated 29 cm lecablock, with a 10 cm insulated inner wall and 5 cm of foam plastic on the outside as a carrier for sto-plaster. Against the ground there will be 10 cm of isodrän.

I think it should turn out well. The walls will be around 45 cm thick after all.

Or... :-/
