An evacuated panel (2) is provided which enables the thermal insulation of a cylindrical body (1) having two substantially rectangular main faces, formed of a flexible envelope (4) made of one or more barrier sheets, and containing a discontinuous or porous, inorganic or polymeric filling material (3). The panel has a thickness such that the ratio between this thickness and the minimum bending radius of the lateral wall of the cylindrical body is small enough so as to enable the winding of the panel without compromising the integrity thereof, and a length such that it allows at least two windings around the body (1). |
