The invention relates to a mineral wool element (7), its fabrication method, and a method for insulating curvilinear surfaces, as well as a wind-load resistant structure comprising a curvilinear building surface, an insulation layer (2) of mineral wool installed thereon, and a sheet metal skin (1) protecting the outside of this insulation layer. The mineral wool element (7) according to the invention includes an insulating mineral wool layer (2) with two opposite main surfaces, one of which is clad with a pliable sheet metal (1) and the other is made up by bare mineral wool, the sheet-metal clad mineral wool layer being pliable jointly with the sheet metal. Such an element (7) can be fabricated either in such a way that one of the two main surfaces of the mineral wool layer (2) is clad with pliable sheet metal (1) and the other is left uncovered, or in such a way that a conventionally fabricated mineral wool element (7) with sheet metal cladding (1', 1"), in which at least both opposite main surfaces of the mineral wool layer (2) have been clad with a pliable sheet metal (1', 1"), is split in two relative to the element's (7) thickness. The element (7) according to the invention enables curvilinear surfaces to be insulated as follows: on a curvilinear surface are installed one or more mineral wool elements of the invention by bending this particular mineral wool element substantially to the conformity with the curvilinear surface geometry in such a way that, of two opposite main surfaces of the mineral wool element, the one made up by bare mineral wool (2) becomes placed against said curvilinear surface to be insulated. |
