The invention relates to panelling material which may be of a decorative or structural type, or both, and which has a very large magnitude strength-to-weight ratio and which is ideally suited for and in certain forms is embodied in, pattern-pre-cut multiple panels adapted to be quickly and easily assembled and edge-fastened together to form a desired building structure and which, because of its inherent flexibility, will provide an extremely earthquake-resistant structure, whether in a low-rise, moderately reinforced structure or in a high-rise, extensively reinforced structure in a manner which will allow the entire structure to flex and move as a unit, thereby virtually eliminating all tendency to separation of different structural materials during even extreme earthquake-caused flexing movements of the structure. The panelling material includes combustion-inhibiting or fire-extinguishing material carried adjacent to or in a disseminated relationship therethrough and taking the form of particles which in one form are preferably of a heat-responsive nature adapted to decompose when subjected to the heat of combustion and to produce, as a result of such decomposition, an effectively built-in fire-extinguishing gas, usually a halogen and, in a preferred form, a halogen containing a substantial quantity of bromine and adapted to prevent the maintainance of combustion originating from other adjacent structures or materials or sources or to substantially inhibit same and to virtually completely prevent the self-supporting maintainance of combustion of the panelling material.

A decorative and structural panel having a large magnitude strength-to-weight ratio comprising: a plurality of laminated panelling material layers firmly bonded together at a plurality of area-spaced, area-disseminated, multi-point interface attachment and junction locations, said plurality of layers of laminated panelling material including at least one convoluted, weight-reducing, strength-increasing, stiffening layer of structural, formed material having a plurality of convolutions extending transversely from a surface plane thereof, said convolutions having outer contact surface portions in contact with corresponding surface portions of a next adjacent layer, at least said convoluted layer being made of a formable thin sheet of high strength material, said laminated panel further including at least one low-density, high specific volume, expanded, compressible, foam filler material layer containing and surrounding a plurality of hollow cells, said foam filler material having a maximized volume-to-weight ratio and carrying a fire extinguishing agent comprising a halogenated compound in particulate form, said halogenated compound being decomposible when subjected to the heat of combustion and adapted to produce, as a result of decomposition, a fire extinguishing gas.
