The present invention concerns a vapor retarder for indoor sealing of buildings, especially roof structures, with at least one barrier layer () retarding passage of moisture vapor, especially water vapor, with the vapor retarder also having an electromagnetic-field-(EMF)-shielding layer (EMF layer) ().

Methods for producing a mineral wool needle-felt and a mineral wool

A product made of bound mineral wool for the cultivation of plants, in which a reversibly water adsorbing agent insoluble in water is bound to the mineral wool, serves for the extensive grassing of soilless grounds, in particular the grassing of roofs. It contains, as a reversibly water adsorbing agent, in particular pyrogen silicic acid. Preferably, the product is available in the form of a felt or the form of a plate with a density of more than 50 kg/m.sup.3, particularly more than 70 kg/m.sup.3.

An electrically conductive surface element, for use in the construction of external facades, is provided with a flame-retardant substance in addition to a radar-absorbing supporting element with electromagnetically active conductive material which has preferably been applied by a printing process.

By combining two measures, namely by using rock wool fibers with a particularly low fiber thickness, and by adding an avivage agent with an unusually high viscosity, it is possible to needle a rock wool felt, without adding any other fibers, to produce a needle felt with high strength and good bendability. If the needle felt is subsequently relaxed with heat treatment, and the avivage agent is also expelled during this treatment, the needle felt is then available as a pure rock wool needle felt, free of any organic additives.

Process for the production of needle felt from rock wool

From a mineral fibre strip supplied in roll form, portions (L) are cut off, the length of which corresponds to the width of a rafter area between rafters plus an oversize designed to produce a clamping effect. Formed in this way, the mineral fibre panels are so inserted into the rafter area that the lateral edges of the mineral fibre strip form the top edge and the bottom edge of the panels. In this way, it is possible to achieve virtually completely wastage-free roof insulation even when the distances between the roof rafters vary considerably, and it is possible to work with material of one uniform and considerable width which is supplied in the form of rolls. By reason of the considerable width of the mineral fibre strip, insulation of one rafter area over its entire length requires only a few mineral fibre panels, with few joints being produced. To facilitate guidance of the cut for separating the portions (L), it is possible to provide on one side of the mineral fiber strip marking lines which can, during production, be generated by a co-rotating roller having linear heated zones.
