Abstract
A wall unit having a vapor-proof evacuatable envelope and a supporting core in the envelope. Wall shells form the outer sides of the element, and screw means extend through and rigidly interconnect the wall shells and thus the element, the screw means having flanges which can be adjusted toward or away from each other to adjust the pressure applied to the wall element by the screw means. Horizontal and vertical reinforcement means are pre-stressed and cast in the outer wall shell.
