A method for the manufacture of doors (1) and other building elements which extend in the form of a sheet and which are formed from a rectangular frame (2), preferably made of a wooden material and exhibiting an internal cavity (4), which frame is intended to be filled with cast plastic material (3) and to be covered with side trims (5, 6) in the form of sheets. The invention permits, amongst other things, the systematic manufacture of doors which exhibit internal insulation made of a cast plastic material and which are imparted with good strength characteristics and temperature characteristics. A mounting sheet (7, 8) in the form of a sheet provided with a number of holes (11) is placed between the frame (2) and said side trims (5, 6). Said cavity (4) in the frame is then filled with cast plastic material (3) of a liquid consistency so that the cast plastic material (3) penetrates through the holes (11) in the mounting sheet and adheres to parts (7A, 8A; 9, 10) situated along adjacent parts of the mounting sheet (7, 8) in question. The invention also relates to an arrangement for the execution of the method. |
