Abstract: The method of mounting of boards makes use of clips, which comprise a plate (4), a first, second and a third hook extending from a front surface (10) of the plate (4), and a plurality of apertures (12) arranged in the plate (4). A first clip is mounted to the frame (3). A first and a second board (2) are arranged adjacent to each other and relative to a first clip such that the first hook thereof supports the first board, and that the second hook thereof supports the second board. A further clip (1) is arranged and mounted to the frame in a different orientation than the first clip at a second longitudinal side of the first and/or second board (2). A third board is then arranged, such that the third hook of said first or further clip supports the third board.
