Insulation

Definition: Thermal insulation can refer to materials used to reduce the rate of heat transfer, or the methods and processes used to reduce heat transfer.

Heat energy can be transferred by conduction, convection, radiation (or when undergoing a phase change, but that's another story). The flow of heat can be delayed by addressing one or more of these mechanisms and is dependent on the physical properties of the material (insulation) employed to do this.
