I am going to replace windows in a house from -81
The existing windows are flush with the interior wall and I plan to do the same.
However, none of the windows have a drip cap above them, so my question is whether I should install them just for the sake of it, or is it simply unnecessary since the window is set so far into the wall??

The next question is about parts of the siding I plan to replace.
The walls are constructed as follows: drywall-plastic-120 insulation-paper-50 insulation-air gap-siding
That is, the paper is inside the outermost insulation, which feels odd.
Should I add new wind barrier, or would that be redundant? (The insulation looks fine under the siding) Is it just as well to renovate as it is built?
 
Regarding the insulation, it could be something like west coast panels on the outermost part, these don't need any wind barrier outside. Perhaps the house has been additionally insulated at some point?

No, it's not Väskustskiva and it's not additionally insulated. They haven't even bothered with 170 timber but have used 120 and attached the external insulation with washers, and the nail battens have some kind of 5 cm plastic spacer to the framework :-)
