Passivhausfenster | The ‘Venster’


The ‘Venster’

Why passive house window (Fenster) is written with a ‘V’ in German. The Passive house ‘Venster’ developed by the company Sigg in Hörbranz, Germany, wins admirers through its exceptional frame construction which means it is possible to use very slim frame profiles. The ‘V’ is used because ‘V’ also stands for ‘Vertrauen’ – trust in the quality of solid wood (Vollholz).
