Abstract
The invention concerns transparent fire break glass panels. The inventive glazing comprises at least two glass sheets and an intumescent phosphate-based material layer, layer which is located between said two glass sheets. The intumescent material comprises pyrogenous silica or a mixture of pyrogenous silica and alumina which enables said material to be exempt from creep deformation at temperatures preceding the expansion of the intumescent material in fire resistance tests. The inventive glass panels have proved heat resistance, and are more easily manufactured than similar glass panels in prior art.
