Abstract

A fire-resistant glazing assembly comprises two glass sheets (1, 2) connected together along their edges by a spacer (3) and a water-containing interlayer (4) between the two panes (1, 2). The spacer (3) is made of silicone rubber. A bead (6) of a heat-activated foaming material is advantageously placed between the spacer (3) and the adhesive sealing material (7) serving to provide the peripheral seal.
