WebU-value is an inverse measure; the lower the U-factor, the better insulated the window. Thus, a single-paned window’s U-Value with a basic aluminum frame is above 1, usually around 1.25, while triple-pane windows may have U-values around .25 or lower. WebThe window U-value recommendation for a Passive House is ≤0.8 W/m2/K (≤0.14 Btu/hr-sf-°F). A U-factor of 0.14 is very low in the current U.S. market and may be hard to find a window that achieves this low value. This low U-factor is not a Passive House requirement, it is only a recommendation. WebThe most energy efficient windows will have a U-factor between 0.30 and 0.15.
