The invention relates to a board for use in interior construction, especially for producing new walls in a room or for paneling wall, ceiling or roof surfaces of a room. Said board is provided on at least two opposite ends, a first and a second end, with connecting means, especially having a groove-and-tongue design, for linking the board with other boards of the same kind. The connecting means facilitate a catch, snap-in or click-in connection with an adjoining board of the same kind. Additional fastening means are provided on the board itself or on two boards linked with each other for fastening the board on a support construction. The invention also relates to a method for producing new walls of a room or for paneling already existing wall, ceiling or roof surfaces of a room. According to this method, a first board is mounted, a second board is linked with the first board by establishing a catch, snap-in or click-in connection on the adjoining lateral edges of the two boards, and the second board is secured by additional fastening means.
