Explanation Of Terms

VLT (Visible Light): Radiant energy from 380nm - 780nm wave-lengths.

(% Transmittance): percentage of visible light directly transmitted through glass.

 

U-Factor: air-to-air thermal conductance of glass and associated air/gas layers; units are Btu/hr.ft2 deg F.

SHGC (Solar Heat Gain Coefficient)fraction of solar energy transferred indoors both directly (radiation) and indirectly (convection/absorption/re-radiation) through the glass (for reference, 1/8" clear glass has a SHGC of 0.86).
