    Linear thermal expansion is usually reported on a graph of expansion vs. temperature. Thermal Conductivity Related to Refractory Thermal conductivity is a measurement of the refractory s insulating ability. In imperial units thermal conductivity is expressed in units referred to as the "k" factor whose actual units are BTU-in/ft2 The specific heat of a tree is much lower than that of a brick. Houses in this area are built of solid oak coniferous trees and also used chipboard. If the tree is cut across the fibers the thermal conductivity of the material does not exceed 0.25 W / M K.
