Thesis

Vacuum insulating glazing (VIG) units are an innovative window technology that has the potential to revolutionize energy-efficient buildings. Windows and transparent façade elements are respon- sible for a large proportion of heat loss in buildings and therefore a large carbon footprint. A vac- uum insulation glazing consists of two or more glass panes between which a vacuum gap is created. This allows thermal effects to be minimized, thus optimizing the energy balance of the transparent areas of building envelopes. To ensure that the individual panes of the VIG can withstand the high stress of atmospheric pressure over several decades, small spacers are inserted into the vacuum gap as shown in the figure below. These are very small and, in addition to the edge seal which hermetically seals the VIG, have a decisive influence on the mechanical and thermomechanical behavior of VIGs. It is now exciting to investigate this influence and to develop implications for the normatively regulated use of the innovative glazing units in order to make a decisive contribution to the establishment of energy-optimized window and facade systems in Germany and Europe.
