With fire protection glazing according to DIN 4102, which consists of a metallic, wooden or silicate frame (6) with glass retaining strips (7) and at least one transparent, homogeneous, reinforced or composite pane, as single or multi-pane glazing, made of glass or glass ceramic and associated Seals (5) or supporting tapes, an expanding medium is arranged between the pane and frame part when the fire sets in, preferably somewhat delayed, in such a way that a sufficiently high pressure builds up between the pane edge and frame part perpendicular to the pane surface such that without additional bending of the edge of the pane, even at high temperatures or after long fire resistance times, pressure on the edge of the pane (2) in the frame (6) is ensured. Intumescent building materials (1), springs, bimetallic strips or systems with gas filling are used as expanding agents. |
