Now there are some interesting programs about the insulation craze with ETICS
It would be wrong, flammable, moisture between ETICS and masonry, etc. etc.
[...]
Our architect says there is no reason to abandon ETICS.
After all, it’s not her house.
Personally, I have no use for ETICS at all; the problem of flammability certainly exists, contrary to Shism’s opinion. Incidentally, what was interesting in the mentioned NDR program (45 minutes) was the type of fire protection test or standard used to still certify ETICS as sufficiently fire-resistant.
A building expert (structural engineer) answered me on the question "ETICS or not" that he would never allow something like that on his own house privately. On the one hand because of fire protection and on the other because of moisture problems, which could already be caused by slightly leaking plaster layers (minimal cracks).
His recommendation for a sensible wall construction: solid (Poroton or also calcium silicate brick), above that multi-layer mineral wool insulation, air layer, and then clinker bricks in front. But of course that is significantly more expensive.
