ᐅ Insulating a New Build with 36.5 cm Aerated Concrete Blocks?

Hello

our new build starts on Monday.

I am considering insulating the 36.5cm (14.4 inches) aerated concrete wall right away while the scaffolding is still in place.

We are building without KfW funding but want to insulate as well as possible.

According to a U-value calculator, I need 200mm (8 inches) of insulation to avoid moisture problems. Is that correct?

Can someone provide more detailed information? Or calculate exactly how thick the insulation needs to be to avoid any issues.

A controlled mechanical ventilation system with heat recovery is also planned.

The last ceiling below the cold roof is made of 24cm (9.5 inches) concrete, and I plan to add 240mm (9.4 inches) mineral wool insulation with a thermal conductivity of 0.035 W/(m·K). Is that sufficient?

I would appreciate any information.

Exactly, me too. Especially since you can easily repaint the bungalow later without scaffolding, say after 10 years, as it is only 2.75 meters (9 feet) high. And the large 80cm (31 inches) roof overhang also provides good protection for the plaster.
