Hallmark Windows and Siding installs Wasco skylights as part of many of their roofing jobs. These are just a few of the models we prefer:

E-Class™
The 'More Sky' SkyWindows^®

Wasco energy-efficient E-Class™ SkyWindow® skylights are designed to deliver more light per rough opening…and install in less time than any of the leading brands. Choose either Venting or Fixed styles, in standard and custom sizes.

•	More Daylight for Less Cost — Our E-Class SkyWindow® skylights sit on the deck, giving you a larger glass area per rough opening compared to competitors' skylights. See dimensions and daylight area specs at right.
•	New Motorized Venting Model — With long-range, thermostatically controlled radio frequency remote, larger vent openings and faster cycle times.
•	10-Year Warranty —Wasco SkyWindow® skylights' superior design, workmanship, and weathertight performance are backed by a non-prorated, 10-year limited warranty covering materials, insulated glass and workmanship. Ask for details.

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 E-Class and G-Series SkyWindows is bronze enamel. Ten baked enamel designer colors are available for all Architectural Series models, and as optional finishes for E-Class and G-Series models. Colors are shown below, approximated by computer display colors. Copper cladding is available on some units.
