** 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.
Your windows themselves have a R-value. A typical window has a 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 a 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 cellular shades to your windows can block as much as 62% of the heat transfer through a window pane according to Alliant Energy.
