Our light-diffusing insulating glass was already used in the existing building. The capillary plate installed in the space between the panes ensured uniform and shadow-free illumination with daylight deep into the room. To maintain this lighting effect and meet modern building physics requirements, Adolf Krischanitz - one of Schwanzer's students - also relied on us and the OKALUX K with optimized thermal insulation for the renovation. This is how to modernize!
