Effekte von Schutzverglasungen in historischen Großkirchen am Beispiel des Domes St. Viktor in Xanten

Effects of protective glazing in historic large churches, using the example of St. Victor's Cathedral in Xanten. The large-scale windows typical of many historical, especially Gothic, church buildings were generally executed as colored stained glass. However, due to the poor insulating properties of these single-pane windows, condensation often forms on their interior surfaces, which, through various chemical and physical effects, leads to irreversible damage to these historic stained glass artworks. To counteract this, these historic window surfaces can be reinforced with so-called protective glazing (an additional, more resistant glass pane). Using the example of Xanten's St. Viktor Cathedral, several essential building-physics effects associated with the protective glazing installed there are discussed.
