In a method for the manufacturing of a door arrangement, particularly a door leaf, a door frame or a dressing of a door, with fire protecting properties, a first and a second door sheet, each door sheet having a first and a second surface (1), is used. A fire-protecting, substantially homogeneous silicate suspension (2), particularly comprising alkali metal silicate and filler, with hardener are applied to at least the first surface of the first door sheet. A filling material (3) is applied to said silicate suspension, whereafter the first and second door sheets are assembled to form a door leaf, so that the first surface of the respective door sheet is faced toward each other. Finally, the fire-protecting, substantially homogeneous silicate suspension is allowed to harden and give off part of its loosely bound water. The door leaf may also comprise absorber means (4). A door frame or a dressing of a door is manufactured in a corresponding way. |
