The objective of this work is to compare the apparent thermal characteristics of ten different types of bi-layered materials using the hot disc technique. In this paper bilayered material refers to the components of a floor that consists of structural board and finishing materials; both are considered mainly wood-based materials (except one slate board as a flooring board). Let us consider the following case. An architect already has candidates for finishing materials for flooring and only needs their thermal characteristics for the final decision. In this context, the architect does not need the theoretical/ideal properties of the finishing material, but only needs their apparent value. A hot disc sensor of diameter 7mm is set on the side of the finishing material, and the process of trial and error is used to achieve as deep a probing depth as possible so that the heat sensor penetrates the flooring board and reaches
