What is the R-Value of the shade?
R-Value refers to the shade's ability to block out temperature differences, such as cold air outside in the winter. A higher R-Value indicates a better insulating shade.
Solar Heat Gain Coefficient (SHGC)
Solar Heat Gain is a measure of how much solar energy passes into your home. In northern climates, a higher SHGC is preferred because it allows the sun to heat the room. While in more southern climates, a lower SHGC is better because it blocks the sun.
