AbstractThis paper reports on experimental results and the use of an advanced hygrothermal computer model called hygIRC to assess the hygrothermal response of various components in wood-frame wall assemblies when subjected to nominally steady-state environmental conditions. There was interest in obtaining information on the drying rates of wall components, in particular oriented strand board (OSB), featuring several different types of membrane in contact with OSB given that such results could provide direct evidence of the degree to which membranes may retain moisture and affect moisture migration. On this basis, the drying response of mid-scale specimens of approximately (0.8 by 1-m) and full-scale specimens (2.44 by 2.44-m) were assessed in a series of experiments undertaken in a controlled laboratory setting. The results were subsequently used to help benchmark simulation results obtained from hygIRC in which a comparison is made between experimental and simulation results.
