Ultraseal™ Manually Venting (EV)

Wasco’s E-Class® installs in 1/3 the time and delivers up to 46% more daylight!

Our manually vented E-Class model (EV) is ready to go right out of the box – no mastic, no step-flashing, no sealants. Our one-piece curbframe and flashing design cuts 90 minute installation to 30 minutes!* Plus, Wasco E–Class skylights deliver up to 46% more daylight!** Our E–Class self-flashing skylights sit directly on the roof deck, giving you a larger glass area per rough opening compared to competitor. Backed by a 10 Year Leak Free Warranty.

The EV model is available in standard and custom sizes, with a wide range of accessories, glazings and finish color options. The EV comes standard with a crank handle that can be replaced with an optional crank handle that allows use of a Skylight Pole for hard to reach skylights.

Wasco’s E-Class skylights feature condensation control without the use of weep holes for maximum energy efficiency. Wasco’s thermally broken vinyl curb frame incorporates a large condensation channel that collects condensation until it can naturally evaporate, eliminating the need for drainage weep holes that allow outside air to pass through the curb, diminishing the energy efficiency of the skylight.

Wasco E-Class self-flashing skylights are for use with thin roofing materials such as composition, slate or wood shingles and shakes up to 3/4″ thick. All E-Class models require a minimum 3:12 roof pitch. A Metal Roof Adapter is available for low profile 1″ standing seam metal roofs with a minimum 4:12 pitch. Standard size models fit 16″ and 24″ on-center roof rafters.

Explanation of Terms:

VLT (Visible Light): Radiant energy from 380nm – 780nm wavelengths. (% 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).

Finish Colors

The standard baked enamel finish for all E-Class® Skylights is Quaker Bronze. Nine additional designer colors are available. Colors are shown below, approximated by computer display colors. Copper cladding is also available.

The eMAX3 Triple Silver Coated Series is a high performance Low-E insulated tempered glass with argon. Also available with tempered over laminated glass.

Hurricane Resistant
Available in fixed model EFHR only. Wasco Skylights with hurricane-resistant glazing meet IBC/IRC/FBC and other stringent state building codes for skylights installed in Wind Zone 3 coastal applications.
