Key Aspect of a Passive House: Fenestration Products

EAS provides a complete offering of European-made products for the Passive House building community.

Passive House Institute Certified Products:

These products represent the state-of-the-art in energy performance, significantly exceeding even the most recent Energy Star and LEED guidelines. With triple-pane glass U-values as low as 0.07 Btu/(hr·ft²·F°) and frame U-values of 0.13 Btu/(hr·ft²·F°), we provide the highest efficiency fenestration products in the US.

Best Passive House Glass in the Industry

Passive House projects require windows with a unique combination of low U-values and high SHGC (Solar Heat Gain Coefficient). It is difficult to manufacture insulated glass assemblies that are both low in thermal transfer and high in solar heat gain. Our CLIMATOP LUX glass offers a U-value of 0.105 Btu/(hr·ft²·F°) and SHGC of 0.62, making it by far the best Passive House combination in the industry.
