The highest thermal conductivity of 01756 KcalmhC was obtained when oak was. The highest values were obtained with boric acid and sodium silicate. This can be attributed to the lower thermal conductivity of the Japanese cypress than that of the Japanese oak as heat flux is known to correlate with thermal conductivity positively which is related to the density of wood. Because wood is a comparatively poor thermal conductor it is sometimes used to provide thermal insulation such as in log houses. The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity k or λ measured in WmK. Conversely the effect of surface coating on the heat transfer was not significant.
Thermal conductivity is often measured with laser flash analysis.
As can be seen in Table 1 thermal conductivity λ values varied according to wood species. Results show that a more careful selection of wood species for non-structural applications can be made in order to decrease energetic consumption. The lowest thermal conductivity of 01465 KcalmhC was obtained with the oak control. Results showed that the impregnation chemicals increased the thermal conductivity. For most materials the amount of heat conducted varies usually non-linearly with temperature. Then density and specific heat measurements.
