We have a window directly above the bathtub in the bathroom, and even though we'd like to keep the window, we've decided to block it to avoid giving the insurance company something to complain about in the event of a future insurance claim. The bathroom is going to be completely renovated, in case anyone was wondering.
However, we don't want to just block the window as this requires a building permit, which delays and increases costs, and it will also be difficult to achieve a neat repair on the outside since it consists of plastered brick. The solution we are considering is to screw the outer pane into the frame and apply some film to make it look like blind glass from the outside. Then we'll block the window from the inside. Naturally, we also want to insulate, and this is where I finally come to my question:
Intuitively, I feel that we shouldn't place the insulation directly against the inside of the window glass; some kind of air gap is probably necessary to prevent condensation and moisture migration. I have some floor tiles left over after installing it in the basement shower; could I put them up between the window and the insulation?

Trying to think outside the box.
If you were to place a tempered glass pane for the window recess/opening (from the inside).
Ensure the waterproofing layer connects outside of this, and that rubber/membrane adheres properly to the glass.
Make the window openable from the outside (for cleaning/maintenance).
Finish with a tile trim a bit inside the glass and tiles to cover the waterproofing layer.
Then you still have light/view but approved waterproofing. Glass withstands moisture/water.
The only problem I see with this is that it must adhere properly to glass, and as far as I know, there's no such design, meaning the insurance company might not like the solution anyway.
And what happens in the closed space between glass and window (moisture-wise).
... maybe it wasn't such a good idea after all....

I have a similar window, when I renovated the bathroom, my first thought was double shower curtains, one against the window and one towards the room. I applied soft sealant between the tiles and the window frame, varnished the wooden frames around the window. Then I thought it would look nicer with a plexiglass sheet to protect the window from splashes. When the bathroom started being used, it turned out to be neither. It seems like people who shower in the bathtub sit down when washing their hair, so only occasional drops end up on the window frames.

In the rental apartment I had before, they had tiled in an openable plexiglass window (seemed to be made specifically for this purpose).
Isn't it a shame to lose a natural light source in the bathroom?

Sure, if I had been able to choose myself the window would have stayed, but I am not the one who wrote Säkra Våtrum, which the insurance companies rely on.
I partly understand why they worry about windows in wet zone 1 because when my kids have finished bathing there isn't much water left in the bathtub.
