Do I need a house wrap for a timber frame inside a stone cottage?

[idontknowwhatiamdoing]

I have a stone cottage with an average of 800mm thick loose granite stones.

I am re-doing the timber frame inside the cottage.

I have a Tyvek breather vapor control layer for the warm side of the timber frame.

Do I need a membrane for the cold side of the timber frame that faces the stone walls, if so, how do I add it when putting up studwork? Do you staple/tape it by section?

I see them putting house wrap (building paper) on timber frame new builds, before the brickwork. So not sure how it works in a retro fitting for a renovation.

The breather paper is normally stapled to outside of the panels so I suppose you could build panels on the ground, breather paper them and lift them into place.  A bit of fiddling where they meet.  I think it is most useful for weather protection before the external cladding is complete, so not really that important for you.

 

With your inside membrane, do this as carefully as you can.  Return it into windows and doors and down to the floor.  If you can marry it up with floor joists, even better.
