Been curious about this for No.1's room as it gets mold on the top corner - which is incredibly cold being a north wall and the lowest point of the roof.
It could be due to the air brick and that the flow of air goes from back (where the bathroom is) to front (where their bedroom is).
However, I'm not sure I'd be up for knocking back to brick, even though it's a tiny room.
Do you have a link to the insulated board you used?
