Loft Insulation - An introduction | TheGreenAge

λ is the thermal conductivity in W/mK. The R-value is measured in metres squared Kelvin per Watt (m 2 K/W) For example the thermal resistance of 220mm of solid brick wall (with thermal conductivity λ=1.2W/mK) is 0.18 m 2 K/W. If you were to insulate a solid brick wall, you simply find the R-value of the insulation and then add the two together.

In crystalline materials, thermal conductivity is a function of the direction that heat flows, directly analogous to the refractive index. In gen- eral, the thermal and optical symmetry will be the same (Washburn, 1929, p. 230). Thus, non- isometric gems will have a conductivity depen- dent on the direction of heat flow during testing.
