Simply put, insulation slows heat flow.
Insulation comes in many forms: blown-in cellulose, fiberglass batts, and spray foam, to name a few. When thinking about insulation it is important to understand the basics of R-Values. (We swear, it’s easy to remember!) R-Value is a measure of a material’s ability to resist the flow of heat. If you remember one thing about R-Values, remember this: higher R-Value = warmer home.
When insulating your home it’s important to think about all the areas of your home that you want to be heated or cooled. In other words, your home’s thermal boundary. Once that is determined, you can work on air sealing and insulating hand-in-hand. *Before adding insulation, it’s important to address air leakage.
