Experimental and simulation results are presented from an investigation of simultaneous heat air and moisture transport in a loose-fill insulation. The aim of the study was to investigate the thermal and moisture effects of natural air convection with no liquid transport present and to validate a numerical model. The structure was placed between two climate chambers at different temperatures. The quasi-steady-state temperature distribution in the cavity of the structure and transient moisture condition were measured, as well as the material properties.
