ENERsign® windows and doors
Solving for climate change in the building sector requires higher levels of energy efficiency of all envelope components especially in cold climates to reduce heating demand annually. Windows and doors are typically the weakest point in the thermal envelope for convection, conduction and radiation.
ENERsign® stands for wood-aluminium windows and doors with the highest standards of energy efficiency. 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 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 the architecture. As window manufacturer ENERsign®, we have specialised in this: to develop 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 let us give you completely non-binding advice on the subject of energy-efficient building.
The highly thermally insulated ENERsign® products incorporate more than 25 years of specialisation and experience.
