Thermal properties

The wood thermal expansion coefficient is comparatively small. It has minor impact at temperatures above 0 & 176; C because the movements caused by changes in moisture content is completely dominant. At temperatures below 0 & 176; C the differences in temperature at different depths in the wood cause tension that can provide cracks such as frost damage to growing trees.
