Standard glazing options for Wasco® E-Class self-flashing skylights include:
Triple Glazed 30-30: An outer and inner pane of Low-E glass coated on the interior surfaces with three layers of silver, with a third pane of clear glass between. Argon gas insulates the two airspaces.

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).
