Hi all,
I need to insultate an internal wall that is outside facing as it gets really cold in the winter and condensation runs down. The room is small so I want to limit the space lost as much as possible. Will a 25mm PIR insulation board with 12mm MDF be sufficient or should I go for the 50mm PIR board? ps I am using MDF on top so can paint straight over rather than have to get a plasterer to skim plasterboard who will probably still charge a full days work!
