By filling such a heat-resistant material in the gap between the peripheral portion 1a of the multilayer glass 1 and the groove 33 of the frame 32, it is possible to more reliably block the flame and smoke at the time of fire occurrence. It is possible to suppress the spread of fire more effectively.
  • the sash window 31 of the present embodiment is provided with the above-described multilayer glass 1, it is excellent in fire resistance.
  • the double glazing and sash window of this invention are excellent in fire resistance, they can be used suitably for fire prevention equipment.
  • the double glazing and sash windows of the present invention can be more suitably used in the outer wall of a building for which fire protection performance is required.

Abstract

La présente invention concerne un vitrage isolé présentant d'excellentes propriétés ignifuges. Le vitrage isolé (1) comprend : une première vitre (2) et une deuxième vitre (3) disposées comme les couches les plus à l'extérieur d'au moins trois ou plusieurs vitres (2) à (4) ; et une troisième vitre (4) disposée entre la première vitre (2) et la deuxième vitre (3). Le vitrage isolé (1) est caractérisé en ce que la première vitre (2) et/ou la deuxième vitre (3) présentent un revêtement de faible émissivité (7, 8) sur leur surface, le revêtement se trouvant sur une surface principale (2a, 3a) sur le côté proche d'une couche de cavité (5, 6), et en ce que la troisième vitre (4) comprend du verre cristallisé.
