ENERsign® passive house windows and doors
Adressing climate change in the building sector requires higher levels of energy efficiency of all envelope components, especially in cold climates, to reduce the annual heating demand. Windows and doors are typically the weakest points in the thermal envelope for convection, conduction, and radiation.
ENERsign® stands for wood-aluminum windows and doors with the highest energy efficiency standards. The best insulation and air-tightness values can be achieved through the interaction of design and material selection.
Our windows and doors are certified by the Passive House Institute Dr. Feist, Darmstadt (Germany) and will help you design new buildings, passive houses or prefabricated houses for thermal comfort, energy efficiency, and moisture control in cold climates.
A high-efficiency house requires only a fraction of the primary energy compared to a standard state-of-the-art building. There are a number of ways to build the future house energy-efficiently. However, the key factors are the building envelope, the ventilation system, and highly thermally insulated windows.
The ENERsign®primus window achieves Uw-values of 0.45 W/m²K and R-values of 12, depending on the glazing and wood type.
Large window fronts with a particularly modern design play a significant role in architecture. As the window manufacturer ENERsign®, we have specialized developing energy-efficient and high-quality windows with the best values for energy-efficient construction and renovation.
Whether passive house, solid house, timber house, old building, bungalow, flat-roof house or design house, whether made to measure, oversized, or individual – let us make you an offer for our windows and doors. Use our window price calculator or allow us to give you completely non-binding advice on the subject of energy-efficient building design.
