The shell has plastics foam plates (2) spaced by rods or bars (3) in the form of shackles, which engage the foam plates in guides. The rods are made of concrete steel and have a diameter of 5-30 mm. The guides may be formed in or machined into the foam plates. The guides may be profiled by milling or cut by heat.
