With a completely new approach to the possible performance levels of a window, it was Franz Freundorfer and Sepp Lorber who have succeeded for the first time to provide a window of class phA+.
The new window has a face width of 58 mm and has been certified by the Passive House Institute for a cold climate.
In the third quarter of 2014, the birth of a new generation of window becomes reality with a pilot project in Styria. Mid-2015, we allowed production to commence by our licensed partners.
