1. A composite support or self-supporting panel comprising an insulating cellular core (1), for example of polystyrene, an interior covering (2) based on mineral fibres and a polymerised binder, characterised in that the covering (2) is formed of a sheet based on discontinuous mineral fibres bound to each other by a polymerised binder, having a content of fibres greater than 70% of the total weight of fibres and binder, the remainder of the covering (2) being constituted essentially of polymerised binder, the sheet having a density from 400 to 1500 Kg/m**3 and being obtained from at least one hot-pressed mat of mineral fibres, the covering (2) being adhered to the insulating core by a structural adhesive and in that an exterior element (3), (5) ensuring mechanical equilibrium of the panel is provided on the other side of the insulating cellular core.
