Abstract (en)
[origin: DE102005002621B3] The insulating module has a surface which is smooth on all sides and encloses a hollow space. Two rectangular metal plates (4,5,6) are available which have bent edges on at least two opposite-facing sides. Both plates enclose a hollow space (1,2,3) and on their edges is a fastening connection between the plates. The module can have a further two or more rectangular plates, of different weights so that the outer external surface does not bend inwards, making a further hollow space(s).
