Abstract
A heat flow meter apparatus is used to monitor the heat flux across a moist specimen of a low density glass-fibre insulation. The results indicate that moisture is transported through the specimen predominately by vapour diffusion. A thermodynamic model is suggested to represent the transport process. This model leads to two moisture transport coefficients characteristic of the specimen.
