Natural Stone Institute What Natural Stone is best for

The center column in the table above lists values for the thermal conductivity of the natural stone types. The k-value is a measurement of the rate of heat transfer through a solid material. If a material has a k-value of 1.00, it means that 1 square meter of material in a thickness of 1 meter will transfer heat at a rate of 1 watt for every

Determination of Thermal Conductivity of Building Stones

Determination of the thermal conductivity of a natural stone plays an important role when considering its suitability for energy saving insulation. Thermal conductivity of rocks changes with rock type since rocks have variable and different mineral constituents.

The Gem Diamondmaster and the Thermal Properties of

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.
