Abstract

The invention relates to a sealing profile (20) for sealing an edge joint (16) between a panel part (12) of a piece of drywall (10) and an adjacent base (8), of a wall or a ceiling, the sealing profile comprising: a main body (22) having a mounting side (24) which forms a support (40) for the panel part (12); and a fastening portion (26) having a fastening side (28). The main body (22) has fastening openings (36) which are mutually spaced apart in the extension direction (P) of the profile and extend from the mounting side (24) at least in part to the fastening portion (26). The invention also relates to drywall (10) having such a sealing profile (20) and to a method for fastening such a sealing profile (20) by means of fastening elements (38).
