Low E Window BasicsLow E windows are a more energy efficient type of window glass that uses an exterior coating that is not to be confused with a window tint. However, low E window glass will give the window a slightly darker look. Low E or low emissivity is a coating that helps to reflect shortwave UV rays when they come into contact with the window glass.
Low E Window PricesTo upgrade from a clear class to a low E window should run approximately $25 per window. To upgrade from clear glass to a low e2 window will typically run $50 per window. To upgrade from a clear glass to a low E3 window will typically run $75 per window.
Energy Efficiency IssuesBecause low e windows reflect heat from the surface of the window glass, they make for a much more efficient windows. Double pane windows will typically use a low e coating on both the outside of the outer window pane and the inside of the inner window pane to reduce the heat transfer from one pane to the other. Low e glass works with a nonmetallic spacer and argon or krypton fills to create an energy efficient insulated glazing unit that is characteristic of a double pane window. |
