How Does Insulation Work?

Proper home insulation can save homeowners plenty of money throughout the years. But how, exactly, does it do this? Essentially, insulation is a barrier that prevents the indoor air from escaping and the outdoor air from seeping in. But how, exactly, does it do this? Read on to learn more:

How Does Heat Travel?

How insulation works depends largely on heat transfer, or, how heat travels. Generally speaking, there are three ways that heat travels from one place to the next:

Radiation

When we hear the word “radiation,” we get images of nuclear wastelands. However, radiation can also work with heat. Heat radiation is where heat travels in a straight line, warming cooler objects. This occurs with heat from the sun or from a radiator.

Convection

Do you have a convection oven? Then you already know how convection heat works. Convection occurs when warm air rises and cool air falls. It’s why your upstairs rooms are warmer than your downstairs rooms.

Conduction

Conduction is when heat transfers via touch. For example, when you touch a hot pan, the heat will travel to your hand through conduction. The denser the material, the easier it is to conduct heat.

How Insulation Prevents Heat Transfer

The main purpose of home insulation is to prevent heat transfer. It may not be able to 100% completely prevent heat transfer, but it can slow it down enough to ensure that your HVAC system isn’t working overtime to keep your home warm or cool. It does this by acting as a barrier between your living spaces and the outside world. For instance, if you install insulation in your attic, then the heat from the sun won’t travel down into the rest of your home.
