On average, approximately 50% of the energy that a household uses is for cooling and heating. There are a variety of factors that will contribute to or otherwise determine how much energy a house uses for these purposes. This includes where the house is located and whether or not it is in need of repairs. Houses that have been updated to include energy-efficient features and appliances will also tend to use less energy for cooling, heating, and other needs. When a house’s interior and exterior is well-insulated and sealed, this can reduce overall energy usage and costs and create a more comfortable home environment.

Different Types of Insulation

While insulation may be available in a variety of forms and materials, these are the most commonly used types:

• Rolls and batts
• Loose-fill
• Rigid foam
• Foam-in-place

When just a small area, such as a crack in the wall, needs to be sealed, foam-in-place, or a foam sealant can be used.
