Heat Storage

In homes the use of materials with a high heat storage capacity (such as brick, limestone, natural stone …) is a big advantage. The heat storage capacity c (J / kgK), or inertia of a building material is the capacity of the material to store heat and to slow issue again. It works regulating.
