This not only means easier transport of the discs, but also that the bracket and frame construction can be made lighter because of the lower load.
  • the fire protection panels filled with fire protection gel are far less susceptible to penetrating moisture compared to the disks with solid silicate-containing intumescent intermediate layers, which in the latter leads to turbidity of the intermediate layer, which requires replacement of the pane.
  • Brandschutzgel filled fire protection panels usually consist of two parallel spaced glass panes of toughened safety glass (ESSG), which are fixed and connected to each other via a lying in their peripheral areas between the glass panes spacer profile and, for example, a polyurethane edge seal.

Through this sleeve-like spacer, the fixing means is guided through the installation of the locking device according to the invention, with which the lock case housing and the counter plate are connected to each other. Since the lock case housing and the counter plate, when installed in a door, project beyond the fire protection plate at upper and lower side edges and rest there on the glazing, the clamping seat for the fire protection panel also acts on the glazing, in particular if the thickness of the fire protection panel is approximately the thickness of the glazing equivalent.
