In order to be able to mount a suspended ceiling in places where the space between the ceiling and the overlying structure exceeds 40 mm there is according to the invention used a generally known metal suspension element (2, 3) with a T-iron (4,5). On these T-irons (4,5) there are mounted plaster boards (6) in that on the back of the boards there are glued two metal strips (7,8), i.e. one with a backwardly bent edge (8) overlapping one of the flanges (5) and a metal strip (7) abutting on the flange (5) in the mounted position of the board. It is thereby possible to place the boards loosely and to take them down according to requirements without any need of tools. The structure will allow the mounting of an additional insulation layer on top of the boards (6). At the same time the structure will appear as plane ceiling surface i.e. with concealed support profiles (4,5). This simplifies maintenance. With a view to being able to stack the boards (6) the strips (7,8) are so short that the strips are clear of each other and the boards, back to back, are turned 90 DEG in relation to each other since the strips will then support the boards (6) evenly.
