Mineral Fiber Insulation — Thermal Conducitvity

A mineral fiber insulation generally used to insulate kitchen furnaces was measured between room temperature and 500°C. As it is typical for most insulating materials, the results for the thermal conductivity increase in a nearly linear fashion around room temperature. At high temperatures, the thermal conductivity increases more markedly. This can be explained by the increased radiative contribution to the effective thermal conductivity.
