Abstract: A kit, which is particularly intended for the fireproof laying of cables and ducts, has endwise connectable, self-supporting components made from thermally insulating material and substantially elongated metal reinforcements. The self-supporting components are duct sections (4 to 12), which in each case comprise a trough section (4' to 12') made from thermally insulating material and externally reinforced by longitudinally continuous sheet metal parts (16) and which has a substantially U-shaped cross-section, and a cover (4" to 12") also made from a thermally insulating material. The trough sections (4' to 12') being in each case equipped for the cover-less laying of the duct (1), are connectable with adjacent trough sections (4' to 12'); and the associated covers (4" to 12") are detachably fixable.

Abstract: A fireproof covering for protecting heat-sensitive material and structures, said covering comprising: pre-shaped mineral wool components, molded to rigid, substantially self-supporting forms with a binder, for surrounding the heat-sensitive material and structures; and, a fireproof coating at least on the outside of the rigid mineral wool components, the coating progressively sintering onto the surface of the rigid mineral wool components under fire conditions and supporting the components as the binder progressively decomposes, whereby heat-sensitive material and structures can be protected from fire conditions for extended periods of time.
