Abstract

At a fire protection gate with an encompassing structure and bilateral steel plate shells, between which a fire protection inset is provided, consisting of at least an insulating element in the form of a plate of mineral fibers, soluble in a physical milieu and reinforced with a binding agent, the composition of the mineral fibers of said insulating element features an alkali/earth alkali-mass relation of <1 and the fiber structure of said insulating element is determined by an average geometrical fiber diameter of ≦4 μm, a gross density in the range of 60 to 130 kg/m3 and a portion of the binding agent, relative to the fiber mass, in the range of 1 to 3 weight %.
