Why does the window protrude inward after installation?
My partner and I bought a house where we are currently having the windows replaced from 1980. After the first windows were put in, I was shocked to see that the window protruded inward. The window installer just said that since it is a prefab house and this is absolutely normal, a drywaller would have to come in.
My question now is whether this is normal, or the window builder ordered too deep windows. Unfortunately, I do not find similar questions on the Internet, where I then either assume that it is normal or so absurd that no one had such a case.

I guess that the guide rails of the roller shutters on the outside were a "natural" limit and that's why he didn't want to lay the installation level. The old windows were probably also really flatter. But he would have had to consider (measure) this beforehand and estimate more effort if necessary. In any case, this is not right.
The photo says far too little. You would have to question the exterior view as well as what was ordered and how thick the walls are. Also: is there a photo with the old window?
What does the wall section look like from above? Where exactly is the window installed and in which wall thickness?
