The Insulating Glass Unit, once developed to guaranty proper thermal insulation for window glazing,
has to assume multiple functions nowadays. Even contradictional demands have to be fulfilled. Highly
efficient insulating systems will become more and more important, even though the technical limits
will be reached soon. IGUs with special inserts can improve the functionality, combining excellent
thermal insulation with an efficient use of natural daylight and sun control. Even energy generating
systems will be integrated into the buildings skin. Such concepts will play a major role in the future to
fulfill the rising energy saving requirements. This development does not only offer new potential for
the planer, it is also a challenge to the glass manufacturer’s flexibility and technical know-how.
However, the buildings envelop will become more distinctive, architects and designers will get a new
range of possibilities to realize their ideas and finally users will benefit not only from an increased
comfort but also from reduced costs for energy and maintenance.
