Conductivity

The thermal conductivity of mineral wool products is composed of three components: the thermal conductivity of fibers thermal conductivity of air and moisture, are between the fibers, as well as the transfer of heat by radiation. Thermal conductivity of a solid foundation as a major component of the total thermal conductivity depends on the geometry…

Manufacturing Process
