Here are 7 ways you can shade your windows from the outside to reduce solar gain.
- Awnings.
- Exterior blinds.
- Curtains.
- Solar mesh screens.
- Overhangs.
- Shutters.
- Shades.
Insulated cellular shades are typically considered to have the highest R-values of all window coverings. ... In heating seasons, tightly installed cellular shades can reduce heat loss through windows by 40% or more, which equates to about 20% heating energy savings.

Wow! I hadn't thought that the window shades can have such great wisdom and scientific backing. What exactly is the R-value?
I can attest to the heat loss, am not sure of the percentage, but I have noticed reduced heat loss when I use them. I use my AC values to estimate this, and yes, it saves energy.

What is the R-value mean? Are you talking about shades on the outside of your windows (or outside of the house)? I'm a bit confused. We do have blinds or shades on most of our windows (inside) and I definitely notice a difference in the "feel" of the room.

The R-value tells you how much a material resists heat flow. The higher the value, the better it is at insulating the home. Windows have R-values too.
