The objective was to measure the vapour permeability values of spruce plywood products (used as exterior sheathing boards), compare the results with those done for OSB and to investigate the drying efficiency of structures through these sheathing products. The drying experiments of simple structures give the possibility to compare the drying efficiency of different sheathing materials when the sheathing is above and below freezing conditions. Structures made of different materials have notably different drying efficiencies under high relative humidity conditions that are representative of their application as exterior sheathing in cold climates.
