Abstract
A deformable sheet material at least partly comprising a sheet metal or metal foil which is corrugated, e.g. by rolling, in continuous waveform in two directions (A, B) substantially orthogonal to each other. The sheet material can comprise aluminum foil with a thickness between 0.005-0.4 mm designed as a ribbon or a strip which prior to the rolling is folded in the longitudinal direction where an intermediate layer, e.g. of aluminum, can be placed between the two material layers.
