Insulate old terraced house

    Hi

    I may have misunderstood but I'm getting mixed messages about internal insulation in an old terraced house without cavity walls.

    Received the following proposals:

    1) Insluation boards should fixed directly to wall and covered with vapour barrier and plaster board;

    2) Batons attaced to existing wall and boards, vapour barrier etc. attached to baton (this is deliberately designed to leave a small airspace between existing wall and insulation)

    Problem is people have told me proposal 2) should DEFINITELY not be done however I trust the builder and have worked with him before. My concern is that warm air will meet cold air in this space and cause damp.

    Perhaps I am misunderstanding point 2). Can anyone help?

    Thanks in advance!
