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