Outside Shades

How do you shade outside windows?
Here are 7 ways you can shade your windows from the outside to reduce solar gain.
  1. Awnings.
  2. Exterior blinds.
  3. Curtains.
  4. Solar mesh screens.
  5. Overhangs.
  6. Shutters.
  7. Shades.
    Do window shades save energy?
    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.
