Heat Insulation and How it Works

How Does Heat Move?

Heat insulation delays the flow of the heat for comfort and helps to prevent damage to your property. Heat flow has three mechanisms, conduction, where the heat moves through the materials, convection, which circulates the heat through liquids and gases, and radiant heat.  Radiant heat moves the heat regardless of what is in its path. Most of the insulation materials that you will find will slow down both convective and conductive heat flows, Radiant barriers will reduce your radiant heat gain.

How Does Insulation Work?

Insulation slows heat down in a number of ways. Fiberglass, and other insulation such as cellulose and Rockwool, traps the warm air while slowing the transfer of air. Foam board insulation and spray foam actually capsulate the low conductive molecules in the structure. Materials such as polystyrene and cellulose have low conductive value. Insulation will help convective heat loss if there is an air barrier. Convection is literally an air transported heat loss. The one downfall of fibrous is that it can be ineffective and very porous when it comes to preventing air transported heat loss. However, Capitol Machine explains that it can retain heat when used with an effective air barrier.

Energy Movement

Insulation shows the three types of heat transfer, and each type of insulation shows the three forms quite differently. A good example is fiberglass, which produces poor convection resistance, as it is unable to stop the airflow.

By understanding the properties of heat insulation, you will be better equipped when it comes to insulating your home.
