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 %.

A fire protection gate, comprising:
- bilateral steel plate shells, with a temperature resistant fire protection inset located between said bilateral steel plate shells;
- at least one insulating element in the form of a plate, said at least one insulating element comprised of mineral fibers soluble in a physiological milieu and at least one binding agent, said mineral fibers of said at least one insulating element having an alkali/earth alkali mass ratio of <1 and the fiber structure of said at least one insulating element is determined by an average geometrical fiber diameter less than or equal to 4 um (microns);
- and
- wherein a portion of the binding agent, relative to a mass of the fiber content of the insulating element is in the range of 1 to 3 weight % and has a gross density in the range of 60 to 130 kg/m3.
