An experimental study of the heat and mass transfer within a fibrous porous layer with ventilation air layer is reported. Air layer was a clearance of 20 mm thickness between porous layer and cooling plate. Glasswood of 100 mm in thickness and 16 kg/m<sup>3</sup> in density was adopted as a testing fibrous porous layer. Experiments were carried out for a variety of parameters such as flow rate of ventilation air, temperature of ventilation air, temperature of the heating room, and humidity of the heating room. The measurements showed that the heat transfer characteristics within the glasswool are mainly dominated by temperature of ventilation air as well as that of the heating room. An increase in ventilation air rate and a decrease in heating room temperature were found to cause a decrease in moisture accumulation within the glasswool. Moisture migration rate was correlated as a function of the Raynolds number and temperature ratio.
