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.
