Heat Transfer in Homes Explained

A photo juxtaposing an image of a house and an infrared version of that imageOne of the biggest contributors to higher electricity and fuel costs in domestic settings is improper insulation and the heat transfer that occurs because of it. Understanding how heat is transferred in and out of your home is essential if you are to find the right solutions for keeping your property cool.

Basically, heat transfer occurs in three different ways: through conduction, convection, and radiation.

Conduction – Conduction happens when heat flows through a material. In homes, this usually happens through solid objects like the walls, the roof, and the windows.

Conduction is observable in areas of the building envelope that are known as thermal bridges. These are points that have very little resistance to heat and so are conducive for the phenomenon to occur. Materials that serve as thermal bridges include metals and glass, both of which can greatly affect your home’s energy performance.

Convection – Convection occurs when the movement of fluids like air or water transfer heat from one point to another. In homes, convection happens through the movement of hot air, when it rises to your ceiling and carries the heat along with it to other areas of your house.

If your home is improperly insulated, you’ve probably noticed how, on a hot day, it is cooler nearer the ground floor than it is upstairs.

Radiation – Radiation from the sun is energy that is transmitted in the form of light waves. It is one of the most common sources of heating in homes because all objects take in infrared radiation. When the sun shines on your roof, for example, the radiation absorbed by the roof can radiate to surfaces like your attic floor or your ductwork, heating those areas in the process.

Unlike conduction and convection, radiation doesn’t need to move from material to material or from particle to particle in order to transfer. It can be transmitted directly through space, even in vacuum conditions.

At eShield™, we offer a variety of products and services to help combat heat transfer in all its forms. For instance, we provide blown-in insulation and air sealing services to limit conductive and convective heat flow in your home. Additionally, we also have radiant barrier insulation systems, which are effective against radiant heat transfer.
