Abstract

The invention relates to a fire screening glazing panel and a method for forming the panel. The panel is composed of at least two structural plys, at least one of which is a vitreous sheet, and a layer therebetween composed at least in part of a heat convertible carrier forming material which material forms a solid porous or cellular thermally insulating body when subjected to sufficient heat, as during a fire. A protective stratum is applied to at least one of the vitreous sheet plys for inhibiting interaction between the barrier forming material and the ply, thereby maintaining the transparency of the ply if it is formed of transparent material, and maintaining its color.
