Abstract: Knowing the thermophysical properties of insulating building materials is essential in understanding heat loss. In this study, the thermal conductivity and thermal diffusivity of five marble samples were measured using the transient plane source (TPS) technique and compared to results obtained through the transient hot strip (THS) method. The TPS technique is nearly twenty times the initial resistance of the THS method and does not require small sample sizes or time measurements. Additionally, the thermal conductivity, thermal diffusivity, and specific heat per unit volume can be obtained from one recording.
