ABSTRACT:
A vacuum packaged insulating structure designed to insulate containers, pipes, and ducts. One type of insulator comprises a vacuum sealed metal foil composite plastic flexible wrap which encloses a double-walled structural frame. The flexible wrap takes the shape of the structural frame and seals the vacuum space created between the walls of the frame. The vacuum space created in the insulator surrounds the cavity to be insulated. In another type of insulator, the vacuum sealed flexible wrap encloses a compressed body of particulate insulating material shaped and formed to surround a duct shaped cavity. The evacuated insulating material prevents the flex wrap from collapsing unto itself and surrounds the cavity to be insulated providing a continuous vacuum form of insulation through the evacuated interstices among the particles of the particulate insulating material.
