  • Patent number: 5698277
    Abstract: A fire-resistant glazing system has two silicate glass sheets (1, 2) which are kept at a distance at the edge via a spacer frame and via adhesive layers (6, 7, 8) and are connected to one another in a sealing manner. The interspace is filled with a hydrogel (9) containing a water-soluble salt. The spacer frame (3, 4, 5) comprises silicate glass strips. The lower thermal conduction of the glass strips compared with known spacer frames made from steel delays warming, which generally results in destruction of the glass sheet, of the edge region of the glass sheet facing away from the fire source. This enables a greater fire resistance period to he achieved for the same thickness of the glazing. Fire protection glasses having the same fire resistance classes, but lower thickness, can thus be produced.
