Hi
One of my properties is a 1960x house with timber weatherboards and no insulation in the walls.
There's no building paper or cavity. Weatherboards are directly fixed to structure.
Weatherboards have splaycut profile, i.e. internal surface of cladding is very flat, without gaps (that are present with bevel-back weatherboards).
Looking at other 1950-60x houses on open homes I notice that most of them don't have any building paper too...
Question: if some day I decide to remove lining and insulate the walls in such a house - what is the proper way to do it when there's no building paper and no cavity?
Installing building paper from the inside doesn't look like a safe option as it will be hard to keep air gaps behind weatherboards, so moisture will be trapped here...
It seems like insulation from outside is the only safe option, but it's very expensive (remove old cladding, install building paper or something rigid, install cavity battens and install new cladding)
Thanks
Ivan
