What do you think about this construction - LECA house

[haganorra]

Sitting and figuring out the construction for the house I want to build...

Concrete slab

Walls from the inside out: Gypsum board - Frame 45/45 with insulation - Lecablock 25 cm - plastered surface - foam plastic 8 cm - plaster...

What do you think about it in terms of construction and insulation?

Skip the internal insulation/gypsum & use 150mm foam instead and finish it with fiberglass plaster.

You avoid expensive materials plus the time/steps to put them up, additionally, you get better insulation value and a 100% heat-retaining wall as a storage.

Insulating both internally and externally is neither logical nor structurally correct.

Best regards, Jawen

If you're building with leca you might as well use an iso leca. That is, a block leca, fst with a type of insulation in it. Then you just plaster both the inside and outside. If you don't want plaster on the inside, you can just frame as usual and drywall!
