ABSTRACT:
When a laminated light transmitting fire-screening panel is formed by sandwiching at least one layer of intumescent material between at least two plies of glazing material, there is a risk that air will be entrapped between the various plies as they are bonded together.
In order to reduce such entrapment of air, the sandwich is assembled while there is present between the or each layer and any panel sheet element which is to be brought into contact therewith, an atmosphere which immediately prior to such contact consists at least in part of one or more materials which is more soluble in the intumescent material than is air, and the sandwich assembly is then subjected to heat and/or pressure to bond it together to form the laminate. Such more soluble material is preferably the vapor phase of a solvent for the intumescent material, for example water.
