  • the fire protection element according to the invention could limit a temperature increase on the side facing away from the fire at a thickness of 22 mm during a period of 120 minutes to 150 ° C.
  • the temperature on the side facing away from the fire side of the fire protection element therefore did not exceed 150 ° C.
  • the carrier consists of a coarse glass fabric which is preferably impregnated with a dry mass and kaolin or silica.
  • the stability of the fire protection element and thus its handling can be further improved if a coarse, impregnated glass fabric having a basis weight of 700 to 1500 g / m 2, preferably from 900 to 1200 g / m 2 , in particular of 1000 g / m 2 is used.
  • the insulating layer is glued to the carrier layer.
  • any common type of bonding e.g. be provided selectively or in strips.
  • the insulating layer is glued to the carrier layer over the entire surface.
  • a high-temperature-resistant adhesive especially based on silica is provided.
  • the layer structure of the fire protection element has a filling material layer, so that the fire protection element has a thickness corresponding to the width of the receiving space of the fire door.
  • the filling material layer is expediently connected to the side facing away from the insulating layer side of the carrier layer with this, in particular glued.
  • the cover layer of a water-repellent shrink film or an impregnated glass fabric so that it envelops the layer structure.
  • the glass fabric provided for the cover layer advantageously has a basis weight of only 100 to 200 g / m 2, in particular 150 g / m 2 .
  • the cover layer is formed by an aluminum foil, which preferably has a thickness of 10 to 50 microns. Such a thing Fire protection element is arranged so that the aluminum foil comes to lie on the side facing the fire and thus reflects the heat of a fire, whereby the thermal insulation performance is further improved.
  • the cover layer of aluminum foil is adhered to the cover layer with a high temperature resistant adhesive. Subsequently, the edges of the insulating layer are then edged with aluminum strips, preferably with aluminum adhesive tape. This results in a good edge protection for fire protection elements according to the invention.
  • a preferred embodiment of a fire protection element an insulating layer 10 of microporous insulating material and a carrier layer 12.
  • a cover layer 14 is provided which completely covers them, the front and side surfaces of the insulating layer 10, however, leaves free.
  • the edges of the layer structure of the insulating layer 10, backing layer 12 and cover layer 14, ie their front and side surfaces 16 are bordered by a cover strip or masking tape 18 so that the cover strip or masking tape 18 from the front or side surfaces 16 to extend to the main surfaces of the layer structure and thus protect the edges of the layer structure.
  • the cover layer 14 is expediently formed by an aluminum foil which is adhesively bonded to the insulating layer 10 in a planar manner, in particular over its entire surface.
  • the aluminum foil has a thickness in the range of 10 .mu.m to 50 .mu.m.
