Answer: it reveals the capacity of absorption or restitution of the heat of a material.

Thermal effusiveness is the intensity with which a material will be able to absorb and restore heat. It also indicates the speed at which the temperature varies on the surface of a material. For example, a wood log and a steel bar, both heated to the same temperature will not have the same thermal effusiveness. Indeed, if you take the wood log in your hand you will feel the burning directly, while the steel bar will first give you a feeling of cold before giving way to the heat. The choice of the thermal effusiveness of the building materials will have a direct impact on the thermal comfort of your home. You too, send us your brico question
