How Insulation Works

Insulation works to slow the heat flow from one space to another by controlling the free movement of air. Controlling air flow is the key to how insulation works, and how it combats the basic properties of heat movement: convection, conduction, and radiation. In this lesson you will be learn to explain the basic concept of how insulation works to reduce air flow, detail what “R-Value” means and know how to distinguish between conduction, convection, and radiation.
