It is the value that shows how much heat the material conducts, thus the insulation level and the value that varies in each material. In other words, when the difference between the temperatures of two parallel surfaces of a material with a thickness d (m) is 1K = 1ºC, it is the amount of heat passing perpendicularly through 1 m surface in 1 hour. The heat permeability coefficient is related to the thermal resistance of the material, if the thermal resistance increases (increasing the thickness of the plate to be used will increase the thermal resistance), the heat permeability coefficient will decrease.
