Planning to extend the house by about 16 m2. An old conservatory will be torn down to the foundations and then rebuilt and insulated, etc., so it becomes a regular room. The question is whether I should use vapor barrier plastic behind the drywall closest to the room. Why is it good? I was thinking of just using wind paper right before the outer panel with battens. Isn't that enough? (The house is from the late 1800s, so the insulation in the house otherwise is not much to have).
Then for the roof. What should the order be: metal roof - battens - paper - beams - insulation - drywall ceiling
or
metal roof - paper - battens - beams - insulation - drywall ceiling
Grateful for answers. Will start tinkering a bit next week

Well! It would be good if you start with trusses, then tongue and groove, underlayment, then you lay the 1st course of battens (spacer battens) over the underlayment from ridge downwards. Then from side to side (support battens, nail battens) with the second course on top of the first battens so that it forms a grid!
On top of the second course, lay the sheet metal which is nailed or screwed, please check first where you should nail/screw the sheets depending on which sheet you choose.. distance and similar to the attachment points, overlap etc. The supplier should be able to answer that.. Sheets for trim boards, ridge sheets, gutters, downspouts, all that comes before you even start considering insulation and the inner ceiling comes last..... Good luck....

Forgot the plastic question... there is no reason to use plastic, feel free to use wind cloth/paper or plastic, but if you use plastic, condensation can occur if you do not intend to use the property year-round with heating. It might be the case that not everyone agrees with that, but if you have a plastic material in a wall and only heat it during certain periods of the year, unfortunately, it easily becomes damp inside the walls...
There should be trusses with insulation between, then an air gap, raw wood, felt, furring strips, load-bearing battens, and then metal sheeting.
If there is plastic in the rest of the walls in the house, it should be in the new space as well. If not, I don't know how it is usually done.

have you put plastic on any of the other walls?
the same building method is not used then as now.
can become too tight
