Characterization of hygrothermal properties of wood-based products – Impact of moisture content and temperature

This paper focuses on the results of measurements of the thermal conductivity, the vapour diffusivity and the sorption–desorption isotherms of 3 types of wood-based materials. disparate and showing the difficulty of studying heterogeneous, hygroscopic wood-based materials, this set of results is a good basis for future work. study is part of an ongoing project, these results will be confronted with those of other partners in order to compare the different methods and to bring out characteristic values for each material. These values will then supply data for numerical calculations of a set of materials under controlled conditions.
