ABSTRACT:
The invention relates to the field of building construction. It is a structure composed of a rigid space form and a partial vacuum enclosed by a double layer of fabric. The enclosed partial vacuum not only acts as a thermal barrier, but also causes a pressure differential between the outer and inner faces of the fabrics. This pressure differential supports the inner fabric layer, and stresses the outer fabric layer in such a manner as to cause it to cling to the rigid space form.
