Abstract

A method for processing intumescent material which forms a layer of a transparent fire-screening panel, which method includes forming a layer containing an aqueous solution of intumescent material on a cyclically moving support, removing water from the layer of material on the support by applying heat, removing the intumescent layer from the support within one cycle of its application thereto in such a manner that the layer becomes reworked or broken, and incorporating the removed intumescent material into a glazing panel.
