LT – Light Transmission in % according to ASTM D-1003, measured between ribs.

SHGC – Solar Heat Gain Coefficient* is the ratio of solar heat gain through the sheet and the incident solar radiation. It takes into account all conduction, convection and radiation effects involved.

* The lower this number, the more solar heat is being blocked.
