This material is made of wood waste (from wood working manufacture or otherwise non-processable wood) which is intentionally degraded with a white rot fungus. Degradation of wood has an impact on its properties and this impact may be positive for re-purposing the use of such material. The main focus is on thermal properties of this material. A decrease in the values of degraded wood thermal conductivity is described by a fraction of the thermal conductivity value of degraded wood to the value of thermal conductivity of undegraded wood. The fraction for spruce wood was 0.8 in longitudinal direction; 0.64 in radial direction and 0.54 in tangential direction. For beech wood, the fractions were 0.82 for longitudinal direction; 0.61 for radial direction and 0.69 for tangential direction. A decrease in thermal conductivity in oak heartwood was noticeable only in tangential direction; the fraction between thermal diffusivity values was 0.67. The values of thermal conductivity are in good agreement with thermal conductivity values of other bio-based thermal insulation materials.
