In the last decade the demand for new functions in building glass products has grown dramatically to realize smart window applications. The realization of these new functions leads to the development of glass processing technologies using laser radiation. By means of laser radiation it is possible to change a broad range of properties of the window glass product. Those laser structures can be seen by the naked eye as well as to be invisible. The new generation of laser scanning technologies speed up the existing laser processes dramatically. This gives the possibility to connect laser processes with existing IGU production processes and reduces manufacturing costs and production time. Furthermore, an optimization of the production sequence of IGU’s is the consequent result of usage these new technologies. For this laser induced processes examples of laser applications will be presented as well as the process tool. In addition, this technology can also be used to recycle old IGUs. Cleaning and stripping processes on dismantled IGU panes lead to a new use of glass that has already been used.
