The theme of doctoral work is to investigate the transport of the heat of natural wooden materials and their composites. Wood -based composites glued by polymer materials belong to the class of sustainable insulating materials with the potential of use in wooden buildings. Good thermal insulation properties predestine them for use in harsh climatic conditions. The effectiveness of their use in real climatic conditions depends on many parameters. The transport of heat in such materials is multi-parametric because it is a simultaneous heat transfer through the components of the structure. Experimentally, transient non-stationary thermophysical methods, specifically a pulse and step-wise transient method and a plane hot disk method, will be used. One task will be to determine thermophysical parameters of anisotropic materials for different directions of their structure. Another task is to assess the suitability of physical and numerical models for heat transport models in an inhomogeneous structure with different geometry of wood filler particles. The results obtained by the numerical model will be compared to the data obtained by experimental methods.
