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.
