Effect of Temperature on Wood - Oaklandwoodfloors.net When wood is heated, it expands. When cooled, it contracts. This property is called linear thermal expansion and linear thermal contraction . This can present some problems for a woodworker when it comes to planning a design for their next project.

Thermal Properties - Austral Ply Wood expand upon heating as do practically all solids. The thermal expansion of plywood is quite small. The average co-efficient of thermal expansion of plywood is 4.5 x 10-6mm/mm/oC.

Thermal properties of wood Wood Products Thermal conductivity declines as the density of the wood decreases. In the direction of the grain, the thermal conductivity of wood is about twice what it is perpendicular to the grain. For example, the thermal conductivity of pine in the direction of the grain is 0.22 W/moC, and perpendicular to the grain 0.14 W/moC.

Thermal Properties - Performance Panels The thermal expansion of wood is much smaller than expansion due to absorption of water. Because of this, thermal expansion can be neglected in cases where wood is subject to considerable swelling and shrinking.
