I have recently pulled the plaster off one of a wall in my house because it was practicaly crumbling away. It is an exterior cavity wall. What I plan to do is to screw batens to the wall then screw the plasterboard to the baten. Beceause It is an exterior wall I would like to use foil backed plasterboard for insulation. I dont have any foil backed plasterboard but I do have plenty of ordinary plasterboard, would i be able to get the same effect if I bought a roll of thermal insulation foil to put between the plasterboard and batens? if so whats the best way to go about it? if not can someone direct me to a cheap place to get some foil backed plasterboard?
Thanks in advance
