Interior insulation wall / timber framing

Good morning,

The entire extension is not built in this way. Only the middle section was constructed in this manner. Glass is fitted in most openings. See picture.

Hello,
so the open fields will still be glazed, and the built-up fields will be provided with [WDVS]? If structural analysis, thermal protection verification, and planning specify it that way, well then.
In any case, I would refrain from interior insulation.

Vapor barriers must always be connected airtight to all adjacent components.

Regards
