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&deg; C., a transverse or shear modulus of elasticity of G* of 1.2 to 2.2 MPa.

Fire protection glazing, method for producing the same and material used in this production method

Fire-retardant sheet element can be composed of several fire protection glass plates ( ). Lateral edges ( ) of adjacent glass plates ( ) therein abut one another. Into the interspace ( ) between lateral edges ( ) a sealing configuration ( ) is installed. This comprises an addition element ( ) and elastic sealing elements ( ). The glass plates ( ) comprise several glass panes ( ) and interspaced fire protection layers ( ). These fire protection layers ( ) do not extend up to the edges ( ) and are sealed in the regions of the lateral edges with a barrier material ( ). No additional frame elements for covering the interspace ( ) and for sealing are necessary.

Fire-inhibiting flat element comprising at least two transparent fire-resisting glass plates

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.

Fire-resistant laminated glass pane assembly

A fire-resistant glazing assembly comprises two glass sheets ( ) connected together along their edges by a spacer ( ) and a water-containing interlayer ( ) between the two panes ( ). The spacer ( ) is made of silicone rubber. A bead ( ) of a heat-activated foaming material is advantageously placed between the spacer ( ) and the adhesive sealing material ( ) serving to provide the peripheral seal.
