why thermal conductivity of building materials is important
Thermal conductivity 1 Thermal conductivity In physics, thermal conductivity, is the, property of a material's ability to conduct heat. It appears primarily inFourier's Law for heat conduction.hermal conductivity 2. Definitions The reciprocal of thermal conductivity is thermal resistivity, usually measured in kelvin-meters per watt (KÂ·mÂ·W â1).When dealing with a known amount of material, its thermal conductance and the reciprocal property, thermalresistance, can be described.
