Abstract: A fire-resistant glass unit is provided having at least two transparent carrier elements, in particular glass panes, and an intermediate layer between the carrier elements, this layer expanding for example in the event of a fire, or a gas-releasing intermediate layer, which builds up a pressure between the carrier elements.

A predetermined breaking point may be, for example, a groove or milled recess, in particular a notch.

Abstract: A fire-resistant glazing assembly has at least two laminated panes between which a transparent layer made of a hydrated alkali polysilicate is placed. The hydrated alkali polysilicate contains no organic antifreeze agent. Thus, on the one hand, better resistance of the interlayer to clouding due to UV radiation and, on the other hand, greater rigidity of the interlayer compound as well as good adhesion of the panes to the interlayer in a fire are obtained.

Abstract: A glazing assembly for protecting against fire exhibits at least two panes adhesively bonded together via a spacer and a water-comprising intermediate layer which fills the intermediate space between the panes. The spacer is composed of a string, applied by extrusion over the peripheral region of a pane, made of a butyl polymer obtained from 40 to 65% by weight of polyisobutylene, from 10 to 25% by weight of carbon black and from 10 to 40% by weight of filler. Within these ranges, the composition is chosen so that the butyl polymer exhibits, at a temperature of 80° C., a transverse or shear modulus of elasticity of G* of 1.2 to 2.2 MPa.

Abstract: A fire-resistant laminated glass pane assembly comprises a glass-ceramic pane resistant to high temperatures and having rough light-diffusing surfaces, the said pane being joined, on each of its two faces, to a silicate glass pane by means of transparent intermediate layers having a refractive index corresponding to the refractive index of the glass and the glass-ceramic. Transparent intermediate plies consist of a thermoplastic polymer having a high splinter fixation effect, and the silicate glass panes consist of tempered float glass. Fire-retarding glasses of this type not only have a high fire-retarding effect, but also withstand the so-called extinguishing water test and, moreover, have safety glass properties with increased safety in respect of injuries caused by splinters.
