Getting Started

Before you hurry to install your basement insulation, you’ll want to examine the space first. Make sure your basement isn’t prone to water damage. All concrete basements can see a certain level of moisture, as concrete is porous, making basements a little tricky to insulate. So choosing the right insulation is important.

Additionally, you’ll want basement insulation that provides the right amount of thermal performance. How do you make sure you’re getting the maximum benefits? Install insulation with the proper R-value.

How do you figure out R-value?

R-value refers to the insulation’s ability to resist heat flow. The greater the R-value the greater the insulating performance. R-value requirements are different based on your location. Colder climates will typically require a higher R-value for even greater thermal resistance. Use the energy code map to help determine R-value for your region.
