thanks for your reply is their a particular type of colotex i need as their seems lots of differant kinds of it

Celotex or Kingspan from a builders merchant..........much better than Polystyrene- same thickness gives better insulation ....it`s foil faced so needs covering

take ceiling down and insulate between joists. plasterboard back over. check out knauf website... very good. if you're handy you can do it yourself but watch the electrics.
