Thermal conductivity is a physical property that appears in any material and measures the ability of material to conduct heat trough it.
When insulation a building it is important to know the thermal conductivity of materials used.
For example, considering a freezer on an ice-cream truck. The freezer insulation must not allow the heat from outside to penetrate into the freezer, otherwise the ice-cream would melt.
So, in this case the material insulating the truck should have a low value of thermal conductivity.
Knowing the values of thermal conductivity for different materials it is important, so we can choose the materials best suited for the job.
