Insulation versus Air Flow

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 learn to explain the basic concept of how insulation works to reduce air flow, comprehend what "R-Value" means and understand how to distinguish between conduction, convection, and radiation
