Insulation or the term 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 transsfer[]

Heat energy can be transferred by conduction, convection, radiation or when undergoing a phase change. These three mechanisms are considered elsewhere.

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 employed to do this.
