#1 WienerKomfortWenster
Historic box windows are magnificent, multi-faceted components that have survived over a century due to their material quality and repairability and have shaped the cityscape of Vienna. Their worth of preservation is also due to the modular structure with the potential for building physical optimization.
Retrofit - the combination of old and new
By supplementing modern technologies with the WienerKomfortFenster, historic box windows can largely be preserved and made competitive again with regard to energy efficiency, comfort and sound insulation. The box window is essentially preserved. Only the inner sash is replaced by a modern wooden interior window element. Installation is quick and unproblematic. Resource consumption and environmental pollution for new production, disposal and transport can be saved and the useful life is extended by further decades.
#2 Heating and cooling at the same time with one system
The summers are getting hotter and the heat waves are getting longer, and room cooling is also becoming more and more important in our latitudes. If you heat the wall or ceiling in winter, you can use the same system to cool the rooms in summer. Wall and ceiling cooling and heating work by means of radiation exchange and save up to 30% on energy costs compared to conventional air conditioning systems. The extra: the wall and ceiling remain free of disruptive air conditioning.
