Explanation Of Terms

Visible Light: radiant energy from 380nm - 780nm wavelengths

% Transmittance: percentage of visible light directly transmitted through glass
% Reflectance Int.: percentage of visible light directly reflected indoors from glass
% Reflectance Ext.: percentage of visible light directly reflected outdoors from glass

Solar Energy: the sun's radiant energy, ranging from 300nm - 4000nm wavelengths

% Transmittance: percentage of solar energy directly transmitted through glass
% Reflectance Ext.: percentage of solar energy directly reflected outdoors from glass

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

Shading Coeff.: fraction of solar heat, direct plus indirect transferred indoors through glass (for reference, 1/8" clear glass has a Shading Coeff. of 1.00)

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)

Relative Heat Gain: total net gain to indoor heat due to both air-to-air thermal conductance and solar heat gain; units are Btu/hr.ft2


Finish Options

Standard finish for all residential units is bronze enamel. Ten baked enamel designer colors are available for commercial models. Colors are shown below, approximated by your computer display, so please contact Wasco for physical samples. Copper cladding is available on some units.
