Passive House Institute notes that with regards to Passive windows and their thermal performance: The window frames must be well insulated and fitted with low-e glazing filled with argon or krypton to prevent heat transfer. For most cool-temperate climates, this means a U-value of 0.80 W/(m²K) or less, with G-values around 50%
Not all windows are created equal. These windows have been third party validated by Passive House Institute and are certified to perform to their advertised performance. That being said, a window is only as good as its installation. Make sure you contact Gomex, to design your Passive House and find out which windows make the most sense for your building. Gomex can provide details on how to best install them to maximize window performance and occupant comfort.
