Abstract (en)
In order to achieve effective thermal insulation, a multi-shell formed piece, in particular a pipe (1) for restoring chimneys, having at least two coaxially disposed, spaced-apart walls (2, 3) with a piece of insulating material (4) made of rock wool provided therebetween is, with manufacture and design being simple, configured such that the insulating material (4) consists of at least one bent insulating plate (5) which is preferably made of trock wool and has a largely constant cross section. Further, the invention proposes a device for disposing said insulating plates (5) and a corresponding process. <IMAGE>
