Understanding R-Value

What Does It All Mean? Understanding the Terminology

R-Value

You may have heard it before: R-Value. But what exactly is it and what does it mean?

Very simply, R-value is a measure of a given material’s resistance to heat flow – how well it resists heat gain or loss. In short, the higher the R-value, the better the insulation it will provide for you.

R-Value and your Windows

Your windows themselves have and R-value. A typical window has an R-value ranging from 0.9 to 3.0. (To put this in perspective, the insulation that is used to build a home today has an R-value in the low 40s).

Several factors influence the R-value of your windows:

  • Type of glazing material
  • Number of layers of glass
  • Size of the air space between the glass layers
  • Thermal resistance of the frame and spacer materials
  • “Tightness” of the installation

R-Value and your Window Treatments

The window treatments you select also have an R-value. The higher the R-value, the more insulating benefits you’ll receive. Adding Comfortex or Hunter Douglas cellular shades to your windows can block as much as 50 % of the heat transfer through a window pane.
