Abstract
A mineral wool article including a mineral wool layer, at least a region of which extends from at least one surface of the mineral wool layer into the mineral wool layer to an impregnation depth t. The region of the mineral wool layer includes individual fibers and is impregnated with an impregnating substance which adheres to the fibers and encloses the fibers without sealing gaps defined between the fibers so as to permit the surface of the mineral wool layer to retain an open surface structure. The gaps between the fibers in the region include bridge formations of the impregnating substance, which bridge formations are configured to permit air to penetrate through the mineral wool layer without essentially being impeded and to trap solid particles and thereby prevent emergence of the particles from the surface of the mineral wool layer. The impregnating substance provides the article with a soft and warm touch.
