The window is made of insulating glass, aluminium and engineered wood, thus making it 99 per cent recyclable. It has a maximum total area of 2.80 sqm and is made to measure. The Ecoline version of the window has triple glazing. All glass panes have a four-sided, 115 mm wide, black screen print edge, which serves as UV protection and cover for the substructure.
