How Insulation Works to Keep Your Home Comfortable

Insulation provides homes and other buildings resistance to heat flow. This makes your home’s temperature stable and comfortable. It’s important to know and understand the different types of heat flow your home is exposed to in order to understand how insulation works. There are three different types of heat flow: radiation, convection, and conduction.


Radiation is when heat is transferred by electromagnetic waves. Anything that is in the waves’ path absorbs the heat. Heat can enter a house through radiation when the sun shines through a window into the house. The heat is transferred into the house and has made the house warmer than it was before the sun hit the window. You can prevent this form of heat flow by installing insulated windows or closing your windows’ blinds.


Conduction is the transfer of heat through solid objects. An example of conduction is the heat you would feel if you were to touch a hot frying pan. Conduction occurs in a home when the weather outside is warm and the heat travels through the walls. This makes the interior of the home warmer. This type of heat transfer is directly related to how well insulated a home is.


Convection is the transfer of heat through gas or liquid. As a gas or liquid is heated, it expands and rises. When heat is transferred to the interior of a home via radiation or conduction, the heat rises in the form of convection. This is why the upper levels of a home are almost always warmer than the lower levels during the summer.

Insulation plays a large role in how a home reacts to heat transfer. Insulation slows the movement of hot air in a home, no matter the mechanism. It keeps your home cooler in the summer and warmer in the winter. Properly insulating your home is extremely important and will keep your home at a comfortable temperature and your energy costs down.
