What is an R-value? How do I find out the R-value of my existing insulation?

R-value is a measurement of how much warm or cool air (depending on the season) your insulation keeps inside your home. If you don’t know how to measure R-value we recommend you ask your contractor for help determining the existing R-value of your insulation. You can also try using our Insulation Calculator.
