How Insulation Works: The Science Behind the Success

how insulation works

To properly understand how insulation works you must first understand how heat moves and flows, which are conduction, convection, and radiation.

First is conduction, which is when heat travels through items. An example of this leaving a metal spoon in a hot cup of coffee and the spoon heats up as a result.

Convection is a circulation of heat as it travels liquids and gases. This is what causes air to form layers in the home with colder air at the bottom and warmer air at the top.

Radiant heat is heat that travels in a straight line and increases the temperature of anything that absorbs the heat. Hot windows and dashboards in the car on a summer day are examples of radiant heat. So now that you know how heat travels, let’s answer the questions of how insulation works.

Insulation and Heat: A Match Made In Heaven

Most common materials used to insulate homes help keep homes’ temperature regulated by slowing conductive heat flow and to a certain extent the amount of convective heat flow within the home as well.

Barriers that block radiant heat are not true insulations but a reflective type of barrier that can help compliment insulation and reduce the amount of heat the insulation has to deal with.

Keeping cooler air inside in the summer and warmer air inside during the winter is the goal of insulating the home. Proper insulation will provide an effective resistance to the flow of heat and this is how insulation works to keep you and your family comfortable all year round!

Heat in the Home: Go With The Flow!

The basic way heat moves throughout the home is as follows. Heat naturally will flow from warmer to cooler areas until no temperature difference is present. Heat wants to naturally balance out so that the temperature inside and outside the home is the same.

In winter months, heat flow will move through air space and travel from room to room and from your main home into areas such as the attic or basement where it can be lost to the outdoor temperature.

In hotter summer months, the heat want to get into your home and will try to negate the cooler temperatures inside the home. The primary method for how insulation works is to slow down this exchange in air temperature form inside and outside the home.

To maintain a comfortable air temperature in summer and winter months, you must eliminate as much heat exchange and transfer as possible.

Keeping cooler air inside in the summer and warmer air inside during the winter is the goal of insulating the home. Proper insulation will provide an effective resistance to the flow of heat and this is how insulation works to keep you and your family comfortable all year round!
