Title
(EN) FIRE-RESISTANT GLAZING
(FR) VITRAGE RESISTANT AU FEU
Abstract
(EN) The invention relates to an "anti-fire" glazing having a set of at least two panes of glass, between which there are located at least two layers of intumescent material based on hydrated alkali metal silicate, the compositions of these two layers differing from one another, one having a molar SiO2/Na2O ratio greater than 3.5 and the other having a molar ratio less than 3.2.
(FR) L'invention concerne un vitrage "anti-feu" comportant un ensemble d'au moins deux feuilles de verre entre lesquelles sont disposées au moins deux couches de matériau intumescent à base de silicate alcalin hydraté, la composition de ces deux couches différant l'une de l'autre, l'une présentant un rapport molaire SiO2/Na2O supérieur à 3,5, l'autre présentant un rapport molaire inférieur à 3,2.
