ABSTRACT:
An insulation arrangement in which a sheath (2) having at least one thin deformable wall (3), for example of foil, contains a powder insulating material (10), with a high vacuum within the sheath. The vacuum can be drawn through an opening (8) after a filter (9) is inserted to prevent removing the powder when the vacuum is drawn. The insulation arrangement can take the form of a panel or a pipe, and the thin wall (3) can be mechanically deformed after the vacuum is drawn.
