The fire-resistant glazing includes one or more glass pane, at least one of which consists of glass containing nucleating agents so that the glass pane is at least partially ceramicized when subjected to high thermal stress sufficient to cause ceramicizing, for example during a fire. The glass may be tempered and contains, in percent by weight based on oxide content SiO , 55 to 69; Al O , 19 to 25 and Li O, 3.2 to 5.0. This glass pane combines the advantages of the strength of tempered glass at low temperature with the stability and long-term resistance to thermal stress of glass-ceramic material at high temperature. The fire-resistant glazing can also include at least one other glass pane made of a conventional glass and at least one plastic layer of PVB film.

A building for containing occupants, with at least one covering element to provide at least one roof portion, at least one wall portion, and at least one floor portion, to provide an interior space to contain and protect occupants from an adverse environment about the building or other structures. The building has an opening to permit occupants to ingress and egress, a window comprising at least one pane, comprising at least an outer pane disposed to contact the adverse environment about the building and at least one inner pane disposed toward the interior space of the building. The pane exposed to the environment about the building or structure comprises a glass material that has a minimized coefficient of thermal expansion. The building also has an insulation to protect occupants from adverse temperature and environmental conditions about the building and a heating apparatus to provide heat to the space provided by the at least one covering element, the window, and the insulation.

Fire-resistant glass, produced by placing between two panes of glass a gel former containing a) an acid aluminum phosphate, b) a reaction product of boric acid with an alkanolamine and one or more alkali metal compounds, and heating the glass to convert the gel former to a gel.

Gel formers comprising acid aluminum phosphate and a reaction product of boric acid and an alkanolamine, and further comprising alkali metal compounds in the aluminum: alkali metal ratio of 1:1.3-2.5 require short gelling times, and form gels having improved melting resistance.

Gel formers having reduced gelling time and forming gels with improved

Fireproofing gels based on amine salts of acid phosphates are characterised in that they comprise an aluminium component, a phosphorus component, an amine component and if appropriate water in proportions such that, at 5 to 30.degree. C. for more than 24 hours, they form a mixture which is capable of flow, and on heating to temperatures above 45.degree. C. they change into a transparent gel in less than 24 hours. In addition to other uses, such fireproofing gels are particularly suitable for the production of laminated glass constructions having a-fire protection action.

C. to 300.degree. C. which is not greater than 7.5.times.10.sup.-6 K.sup.-1 and having a rough face for which roughness, R.sub.tm, is not less than 0.1 .mu.m; and at least one layer of intumescent material directly bonded to and in contact with the rough face of the at least one rough-faced ply.
