In my Victorian house the ground floor external wall is double skin downstairs, but for reasons unknown the same wall upstairs has had the inner skin removed and replaced with stud work ? There's also an rsj holding up the first floor joists.
I've knocked an inspection hole, there's about a 4inch cavity and the timbers appear in good order.
Anyway I have some small areas of damp up the corner of the room ( this wall ) which appears to be condensation as the brickwork is dry and the plaster in good condition too. It's basically the cold corner of the house.
Anyway I've ordered some trickle vents for the upvc double glazing to help air flow but I have three questions.
1: Can I use expanding foam injection to insulate behind these cavities ? ( of course I'd be guuessing not to miss any areas ).
2: Will the wall being warmer prevent the damp / condensation ?
3: is it pointless only insulating the one wall of the room ?
My daughter has asthma so I'm very conscious of the bedroom conditions.
Any help is greatly appreciated.
