In this study, experimental measurement has been conducted for the polyurethane foam on the variation of weight with time, in which gas in the foam has diffused out and in. It is well known that the celluar foam insulation such as polyurethane foam has been aged by the degradation of the thermal conductivity. It is noted that the aging of foam has been resulted from the diffused gas to the cell, in which is initially consisted of CO<SUB>2</SUB>, afterwards air from the environment has been replaced in the cell. Likewise, the variation of the cell gas content with time is mainly influenced the increase of thermal conductivity for the celluar foam. The weight of the foam has been also changed as the gas diffusing in and out. In this study, the weight measurement method has been proposed to test and convert the effective diffusion coefficient of CO2 and Air, and the result has compared with the gas analysis method.
