### G-value

Is a measure of how much solar heat is released through the glass.

### U-value

A value that shows how much heat passes through the glass.

### Solar reflectance

A value for how much of the sun is reflected away when it hits the shield.

### Solar transmittance

A measure of how much of the sun's energy goes through the window and heats the room inside.

### Solar transmittance

The total transmission through windows and solar shading.
