Using Temperature to Control Condensation in Cold Climates

Initially, water vapor diffusion was seen as the likely culprit for condensation problems; designers and consultants spent hours running and analyzing wall assemblies using the dewpoint method. With such analyses came the concept the wall system should be tuned for maximum condensation resistance by altering or selecting the appropriate permeability of the wall components. However, to create a truly robust wall system with the greatest condensation resistance and drying potential, designers need to look at altering the temperature profile of the wall assembly by moving insulation as far as possible to the exterior of the wall.
