Can dry lining help insulate a cold room?

Dry lining can help insulate a cold room when thermal insulation is included in the system. Insulated plasterboard combines a plasterboard facing with a layer of insulation, while a timber or metal frame allows mineral wool or rigid insulation to be installed behind the boards. This can reduce heat loss through external walls and make the room feel warmer. The improvement depends on the insulation type, thickness and quality of installation. Poorly sealed joints, gaps and thermal bridges can reduce performance and create cold spots. Moisture movement must also be considered, especially in older stone properties. Dry lining without added insulation provides only a small thermal benefit. A proper survey can identify the best wall build-up for improving comfort while avoiding condensation behind the boards.
