Abstract:
1. A method of making a window unit, the method comprising: a) depositing a solar management coating on at least one of a first glass substrate and/or a second glass substrate, the solar management coating comprising at least one layer for blocking at least some IR radiation; b) coupling the first substrate and the second substrate to one another so that the solar management coating is on a surface facing a gap provided between the first and second glass substrates; and c) depositing via vapor deposition a layer comprising silicon oxide on an exterior surface of the first substrate, wherein the vapor deposition comprises a process of converting silicon tetrachloride into silicon oxide in the presence of H2O, wherein the layer comprising silicon oxide forms a hydrophilic surface having a water contact angle θ less than or equal to about 20 degrees, wherein said vapor deposition occurs at an ambient temperature, and wherein the layer comprising silicon oxide has a refractive index (n) of from about 1.4 to 1.6.
