External insulation with smaller cuttings

Hello everyone,

we are currently building a KFW55 house. The exterior insulation is being done right now, and I am not sure if everything is okay.

Insulations were installed there that are only about 3cm wide (see picture). I am concerned that the plaster might crack at some point. The site manager (by the way very competent, and often on the construction site) says that everything is according to the norm. What do you think?

That looks fine. Larger joints are problematic. But in your photo, they look nice. Anyway, a fabric plaster / fabric filling will be applied over it to prevent crack formation.
