ABSTRACT:
An article of insulation and a method for making same. Outer sheet-like elements (22,24) of elastic deformable material are secured by adhesive to a base element (20) of rigid deformable material in a particular pattern which defines unbonded areas which are each bounded entirely by adhesive. The combination of the two outer elements (22,24) and the base element (20) is then deformed, following which the base element (20) retains its deformed shape while the outer elements (22,24) spring back to their original shape, leaving voids between the base element (20) and the outer elements (22,24) in which there is a partial vacuum.
