The invention relates to a system (1) for sealing an empty box in a wall. The wall comprises masonry (2), an isolation layer (3) located on the masonry, a density paper (4) located on the isolation layer (3) and an inner lining (5) located thereon. An empty box (7) is inserted into an opening in the wall, wherein one or more empty conduits reach from the masonry (2) into the empty box (7). According to the invention, there is an elastic collar (9) located between the empty box (7) and the isolation layer (3) through which the empty conduit(s) (8) is or are guided, wherein the insertion of the empty conduits (8) through the collar (9) is sealed by stabilized passage points (92) and wherein the elastic collar (9) is fastened on the outer edge of the opening on the isolation layer (3) or the density paper (4) by a fastening bracket (91). |
