ABSTRACT:
A fire-screening panel is provided that maintains its effectiveness in preventing fire propagation even after aging of the panel. The panel comprises a first structural ply formed from a vitreous sheet, and a second structural ply, with a layer of intumescent material disposed therebetween. Other plies may also be provided, and the plies are clamped together in face-to-face relationship, and/or bonded together. At least one ply of the panel has an infra-red reflecting coating disposed thereon, remote from the intumescent material, which coating provides for the retained effectiveness of the fire-propagating properties of the panel despite aging thereof.
