Abstract
A flame-retardant composite glass including a plurality of glass panes and a flame-retardant intermediate layer that is arranged between two first glass panes and includes a flame-retardant material that foams or swells up in the event of a fire, as well as an attack-resistant layer having a transparent plastic that is solid at room temperature. The flame-retardant composite glass has, between the first glass panes, an edge compound extending along and around the edges such that a chamber filled with said flame-retardant material is defined by the first glass panes and the edge compound. Between at least one of the first glass panes and the flame-retardant material, a primer layer is arranged that includes a material whose adhesion to the flame-retardant intermediate layer and/or to the glass pane becomes weaker in flame-retardant test conditions than it is in room temperature conditions.
