A heat shield arrangement includes several tiles 1 and several fasteners 6 for attaching the tiles at a spaced distance to a wall 2 to form an interspace 4 between the wall and the tiles which can be supplied with cooling air. At least one sealing element 3 is positioned between adjacent tiles 1 to provide a seal between rims 5 of the adjacent tiles 1. The rims 5 of the tiles 1 which are to be sealed are maintained at a spaced distance from the wall 2 by the fasteners 6 and the sealing element 3 is positioned remotely from the wall 2 and in abutment with the rims 5 of the tiles 1, with the sealing element 3 being allowed to float over the rims 5.
