The solar optical properties are used to calculate the shading coefficient.
The shading coefficient represents the percentage of solar heat gain that is transmitted to the interior through the glass and shading system.
Ts = Solar Transmittance 1/8CL = 1/8" Clear Glass 1/2CL = 1/2" Insulating Clear Glass
Rs = Solar Reflectance 1/4CL = 1/4" Clear Glass 1CL = 1" Insulating Clear Glass
As = Solar Absorptance 1/4HA = 1/4" Heat Absorbing Glass 1HA = 1" Insulating Heat Absorbing Glass
Tv = Visual Transmittance
