Insulated plasterboard is a different approach to insulation. Insulated plasterboard is a combination of a layer of plasterboard adhered to a layer of foam insulation. During building, the insulated plasterboard is attached directly to the framing material. However, as a retrofit the board can be attached directly to existing plaster (or the original can be removed) especially where there is no or difficult access to the cavity, and the room is large enough to allow some loss of floor area or ceiling height due to the thickness of the board.
