As part of the project "3encult" smartwin producer Menuiserie Andre developed a new window system for listed historic buildings. A single glazed window frame externally with a triple glazed and particularly narrow window frame internally achieves a certified passive house window of the grade phA with a historical look.
Franz Freundorfer presented his summary for the lecture at the 16th International Passive House Conference in Hanover in 2012.
