thermal properties of wood wood products

the thermal conductivity of wood is relatively low because of the porosity of timber. 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
