Is it reasonable to use material for the exterior wall without insulation?

Hello everyone,

I am new here in the forum and am currently planning a house.
I already have an offer, which includes exterior walls made of 36.5 Poroton without external insulation, just plaster.
Does that make sense or would you rather advise against it?

Would you have reinforcement applied in the exterior plaster with this construction method to prevent possible cracking?

It reads in my construction performance description as follows:
When executing the exterior plaster system, a lime-cement plaster with a thickness of 1.5 cm - 2.0 cm is applied to the Poroton masonry. On top of that, the finishing plaster, executed with 2 mm synthetic resin plaster, is applied.

They only have reinforcement in the version with external insulation in the construction performance description, which doesn’t apply to us.

I am curious about your opinions.

Regards, Alex

Reinforcement is standard for exterior plaster. 36.5 without insulation is possible if at least 0.09.

We live in a house like that. Monolithic wall construction. Without insulation boards, no algae-covered facade on the north side, the mailbox is secured, what more could you want?

Maybe I am the only one who doesn't understand the question. What exactly are your concerns?

Ignorance and the image in the head with insulation is always good...

What is meant by 0.09, the thermal conductivity?
