Abstract

A fire-resistant glazing panel comprises at least two glass sheets, between which is placed a transparent fire-resistant material made of a cured alkali metal polysilicate hydrate. At least one glass sheet is provided, on its surface which is in contact with the fire-resistant material, with a primer layer, the adhesion of which to the fire-resistant layer decreases at the temperatures of the test of behaviour towards fire. At the temperature of the test of behaviour towards fire, the glass sheet exposed to the fire separates completely from the fire-resistant material. For this reason, the polysilicate fire-resistant shield remains intact, even when the glass sheet exposed to the fire shatters and when the fragments fall off.
