Abstract: The present invention concerns a packaging unit (1) for several pipe sections (2) of mineral wool with a packaging material (5), which surrounds the several pipe sections (2) to form the packaging unit (1), with the packaging material (5) arranged around the pipe sections (2) under pressure, the pipe sections (2) are folded within the packaging unit (1) with reduction of the pipe section cavity, and the pipe sections (2) are formed elastically such that, in the folded state, recovery forces for restoring the unfolded initial shape are built up. By means of the packaging unit (1) of the invention, several pipe sections (2) can be transported and stored very economically. In this connection, pipe sections (2) are not restricted in their functionality, but, after removal from packaging unit (1), may be used directly and without restriction, e.g., to insulate chimneys.

Abstract: The present invention concerns a thermal insulating element made from heat-resistant material, preferably mineral wool and especially rock wool, with this thermal insulating element capable of being inserted into a wall, ceiling or roof opening or the like, having at least one opening along a linear axis passing through the thermal insulating element. Its special characteristic is the fact that in the opening is arranged at least one pipe shell made from a winding-like, heat resistant fiber material, preferably mineral wool and especially rock wool for accommodating a hot pipe, with the fibers of this pipe shell having an essentially two-dimensional orientation in the circumferential direction of the shell.
