Is insulated plasterboard worth using?

Insulated plasterboard can be worthwhile in rooms with cold external walls, poor thermal performance or limited space. It combines plasterboard with a layer of insulation, allowing both materials to be fitted together. This can make installation quicker and create a thinner wall build-up than some separate framing systems. Insulated plasterboard may reduce heat loss, improve comfort and make internal wall surfaces feel warmer. However, it costs more than standard plasterboard and must be installed carefully. Gaps between boards or poor sealing around windows and floors can create cold spots. Moisture control is particularly important in older stone properties, where unsuitable materials may trap water vapour. Whether it offers good value depends on the building, insulation thickness, available space and heating costs.
