New Possibilities of Sun and Glare Protection with a Structured Switchable Glazing

Glazing units used for architectural applications have an enormous potential for optimization. Currently, daylight management as well as solar and shading control can be provided only through a combination of various individual elements, such as glass panes, venetian blinds and additional glare pro...
