Passive house windows

The window by the standard of a passive house has a particularly high thermal insulation. The heat transfer coefficient U w must be less than or equal to the European standard 0.8 w / m 2 K. Any window that has a smaller or the same U w value of 0.8 W / m 2 K is a passive window and according to the currentOrdinance on energy saving 2014 is intended for use in passive houses and corresponds to the Kfw program.

Passive house windows / Technology that impresses!

The properties of windows with passive house standards owe their excellent thermal insulation to high-quality technology combined with triple glazing. The U-values of the finished window depend on the U-value of the frame, the glazing and the spacer used for the edge of the seal. Check the detailed information on the U-value calculation on our U-value info page.

On the example of the Eforte system profile, 12.6 ° C shows excellent insulation, and it is precisely inthe inner and warm side of the window prevents cold and condensation.

Windows for passive houses have a high permeability of solar energy. Because natural heat can be used more efficiently through solar radiation, the energy balance of a building is improved and the annual consumption of primary energy is reduced. Passive house windows are primarily used for the purpose of reducing energy and heating costs, and at the same time contribute to living comfort.
