Insulation protects from these losses by sealing off and padding heat-exposed points.

There are many types of insulation that you can use in your home.

Home insulation can save you money all year, no matter what season.

How can home insulation help with energy savings?

The top two contributors to energy consumption at home in the United States are heating and cooling.

Heating and air conditioning account for approximately half of household energy costs. They account for between 50% to 70% of total energy consumption.

Incorrectly or uninsulated homes can result in energy losses equal to having a window open year-round or a hole in your walls.

Homeowners can save 11% on their total energy bills by installing insulation and sealing air leaks. This is in addition to saving about 15% on cooling and heating costs. They also reduce their carbon footprint, making their home more comfortable.

How Does Insulation Work?

Three things are essential to understanding how insulation works:

  • Knowing how heat flow works
  • Where in your house do you need to insulate
  • Understanding the type of insulation you should install

Insulation is designed to stop unwanted air movement and increase thermal resistance. Insulation must target heat and heat movement to achieve this.

There are several ways heat can flow and transfer energy:

  • Conduction is the first. Conduction is when heat travels through solid materials, such as when the sun heats uninsulated roofing, radiating heat into the home.
  • Convection is the second. Convection refers to heat transfer, whether in liquid or gas form. Fluid motion causes warm air rises, and cool air descends, resulting in hotter basements and attics.
  • Radiation, or heat transferred through light, is the final form of heat flow. This is evident in the heat and light that radiates from a campfire or the sun’s heat.

These three types are examples of heat energy that show heat will travel naturally to lower temperatures to disperse heat until all temperatures are equal.

This means that heat from your home in winter will always be going to the cooler parts of the house.

Heat will be transferred from a shared living area to basements, garages and — most inefficiently — outside.

Heat can move into your house in the summertime and attempt to heat the cool air from your air conditioner, drawn shades and fans.

Your heating and cooling systems work together to maintain the temperature you desire. Heat flow, transfer or escape by mitigating motion can help prevent temperatures from rising and keep your HVAC system from working too hard.

R-Value: How do you measure thermal insulation?

Insulation can be measured by its ability or inability to resist heat flow.

The R-value is the rate at which insulation resists heat. It is dependent on material density.

The R-value of most insulation types depends on how dense it is. It will protect against heat transfer and airflow.

Homeowners should know that R-value and density ratios can change depending on the insulation type, location, climate, and HVAC systems.

Compressed insulation, for example, can be loose-fill insulation that is poured over loose-fill insulation or batt insulation. Because its weight presses on itself, it will cause compression. However, this won’t necessarily translate into thickness or R-value.

Thermal bridging is insulation installed between floors, ceilings, and walls. It is determined by the total insulation value applied to the surfaces, not its thickness.
