Abstract: The fire resistant interlayer for use in a fire resistant element is suitable for use in a fire resistant element. The fire resistant interlayer is arrangeable between two support elements. The fire resistant interlayer is a silicon based polymer, wherein the polymer is polymerised from starting component comprising silicon. In particular the polymer is polymerised from a dispersion of SiO2 nanoparticles, and/or silicic acid, a silane compound; in particular halogenated silane, in particular chlorinated silane and/or fluorinated silane; a silanol compound, a siloxane compound a derivate thereof and/or a mixture thereof dissolved, dispersed and/or emulsified a solvent.

Abstract: The fire-protection glazing includes at least two glass panes, between which a transparent layer of a fire-protection layer is arranged, wherein the fire-protection layer includes a hydrogel. The educts of the fire-protection layer include water-soluble, non-toxic monofunctional monomers in an acid environment as well as at least one bifunctional or polyfunctional monomer and, as the case may be, an initiator, in an aqueous salt solution or in an aqueous salt dispersion. The monofunctional and the bifunctional or polyfunctional monomers are not toxic, not carcinogenic and not mutagenic.

Abstract: A light-permeable heat protection element having a first and a second support member and having an intermediate layer between the first and the second support member. The intermediate layer has a cured alkali silicate gel formed of an aqueous alkali silicate solution and a silicon dioxide compound. The alkali silicate gel of the intermediate layer thereby has a molar ratio of silicon dioxide (SiO2 to alkali metal oxide (M2O) greater than 4. Furthermore, the alkali silicate gel has 0.05 to 0.14 weight percent of lithium silicate.

Abstract: A fire-protection pane, including at least one float glass pane with an atmosphere side and with a tin bath side, at least one protective layer, which is arranged in a surfaced manner on the atmosphere side and/or the tin bath side, and at least one fire-protection layer, which is arranged in a surfaced manner on the protective layer. The protective layer is a multi-layer layer structure and includes a first sub-protective-layer of metal-doped silicon nitride, and a second sub-protective-layer of a tin/zinc oxide or a doped tin/zinc oxide.
