Abstract (en)
A fire door with increased sound insulation - the manufacturing process characteristic in that on a corrugated cardboard (3) a glue pattern (P) is applied preferably polyurethane and preferably regularly spaced, not linearly and not evenly, preferably from 8 to 18 points on the surface of the corrugated cardboard (3), then the corrugated cardboard (3) is engageably connected with the layer of rockwool (2), and then the fabricated element is rotated and on a corrugated cardboard (3) the glue pattern (P) is applied preferably polyurethane and preferably regularly spaced, not linearly and not evenly, preferably from 8 to 18 points on the surface of corrugated cardboard (3), then the corrugated cardboard (3) is engageably connected with the layer of rockwool (4), the fabricated composite sandwich board (K) is used as the inner panel of the door leaf in a standard production process so that on the fabricated steel profile of sash cover (1) the glue is applied and then the woodframe of laminated wood is inserted, then the composite sandwich board (K) is inserted, and then on the upper surface of the composite sandwich board (K) and the woodframe the glue is applied, and then the steel profile of sash cover (5) is slided over closing the construction of the door leaf, in the next step the fabricated door panel is placed in a heat press at least for 7 minutes.
