ABSTRACT:
This invention provides a panel for use in doors or walls of vaults or strong rooms which is lighter in weight than conventional materials while providing comparable attack resistance. The panel consists of a layer of ceramic tiles adhesively secured to an energy-absorbing backing layer. Both faces of the panel are covered by sheet metal, and when the panel is used in constructing a door, the edges of the door also have a suitable metallic covering.
