Abstract: The present invention relates to a compressible construction to be used as isolation or as packing material, comprising equidistant bellow-like compressible layers, which are interconnected by a zigzag folded strip which is alternately connected to the layers. Short projecting parts are positioned between the zigzag strip and the layers to add support. In the folded compressed condition when not in use, the construction has a very small volume, while in the expanded condition it is able to act as a heat insulator and pressure, shock and vibration resistor. Important features of this construction are its small volume as it can be compressed when not in use, its ability to isolate from heat, to resist pressure, shocks and vibrations.
