Heat-insulating, fire-resistive cover for protecting wood, concrete or steel building components, consists of a plastics- and/or elastomer-contg. cover layer, provided, on side facing the building component, with a heat-insulating carrier layer. The carrier layer is provided with fillers contg. over 15 mol.% P and over 15 mol.% N. An appts. for producing the cover unit is claimed. The web- like insulating layer is impregnated with the fillers in an impregnating bath and pre-dried in a pre-drier. The cover layer is pressed against the insulating layer in a pressing device. The 2 layers are then strongly bonded to one another by hardening in oven at 70-120 deg.C. The cover unit can be used to cover roofs, building fronts and for covering and surrounding pipes. |
