Abstract: An experimental research has been conducted to assess the thermo-physical properties of five building materials in both dry and moist state: beech wood, autoclaved aerated concrete and brick, and in dry state for expanded and extruded polystyrene. The objectives of the paper envisage the measurement of the thermal conductivity of these materials through an unsteady state method. The experimental method used in determining the thermal conductivity is based on the principle of temperatures at the interface of two homogeneous semi-infinite bodies of previously altogether different temperatures. The advantage that this method provides lies mainly in the short measuring time and the small temperature rise across the samples. The experimental tests have been accomplished by numerical modeling by means of a computational program based on the finite element method (FEM). The latter have been conducted bidimensionally, under transient state conditions for different lengths !
of the five materials in dry state. The numerical and experimental results have shown a good agreement for the temperature of the contact area.
