Abstract: A window assembly includes an electro-optic element which has a first substantially transparent substrate defining first and second surfaces. The second surface includes a first electrically conductive layer. A second substantially transparent substrate defines third and fourth surfaces. The third surface includes a second electrically conductive layer. A primary seal is disposed between the first and second substrates. The seal and the first and second substrates define a cavity therebetween. An electro-optic medium is disposed in the cavity. The electro-optic medium is switchable such that the electro-optic element is operable between substantially clear and darkened states. An absorptive layer is positioned on the fourth surface of the electro-optic element and a reflective layer is positioned on the absorptive layer.
