The overall objective of this research project is to develop highly thermally insulating and slim window and facade systems with hybrid glazing consisting of vacuum insulating glass and face glazing (VIG+), to test these and to apply them in practice. In view of the new Building Energy Act (GEG), FFS-VIG stipulates the prerequisite that window areas in new buildings can remain the same size or even be larger. In addition, the low installation thickness of VIG+ enables its use in existing buildings, thus opening up enormous energy-saving potential. A front glass pane guarantees a high level of durability of vacuum insulating glass systems and enables the insertion of multifunctional components. Due to the considerable improvement in insulation value, the amount of heat loss through the window area is halved compared to current triple insulating glazing. However, there is still a lack of efficient system solutions in the field of thermally optimized frames and façade profiles in order to be able to exploit this potential. For this reason, the development of practicable and economical system solutions for (VIG+ and frames) within the framework of FFS-VIG is essential for a rapid market entry and broad market penetration. The project results form the basis for product standards (VIG and VIG+) for the European market, and the application of the systems in practice is to be accelerated by obtaining building approvals (ZiE, abZ) for the developed glasses.
