A cellular air bag insulator and its uses in insulating a house window, a house door, a house wall and a process equipment, such as an evaporator, a refrigerator and a distillation column. A cellular air bag insulator can also be used as an instant shelter and can also be incorporated into an insulated panel. A cellular air bag insulator is a light weight insulator and comprises an outer enclosed bag and an expansible and collapsible multicompartment core such as a honeycomb structure joined to the outer bag. It can easily be inflated and deflated.

An inflatable and deflatable cellular bag insulator that comprises (a) an inflatable and deflatable outer enclosure that is made of a flexible and non-porous film material, is expansible mainly along a first direction and has a front surface and a rear surface upon inflation, the front surface being adapted to face the area to be insulated while in use, (b) a valving means for inflating and deflating the enclosure, (c) an inner core that comprises at least one sheet of stacked and mutually bonded flexible film material, each sheet being joined to each neighboring sheet by a set of parallel linear joints laid in the direction substantially parallel to the front surface and substantially perpendicular to the first direction said joints extending substantially the entire length of the sheets forming expansible spaces, and the two sets of linear joints on both sides of an inner sheet being in staggered positions to each other, (d) linear joints joining the inner core to the outer enclosure, (e) at least one passage for transferring gas from the valving means to the expansible spaces of the inner core, that, upon inflating with a gas, the linear joints and the film material in the inner core and the outer enclosure are pulled away from each other to form an array of layers of parallel compartments extending from a first end to a second end and filled with the inflating gas, reducing heat transfer through the inflated unit by reducing convective flow of gas within the enclosure and requiring heat to pass through the multilayers of the gas filled compartment, wherein the improvement that comprises closing a portion of the parallel compartments at the first end and closing a portion of the parallel compartments at the second end to thereby reduce convective movement of gas contained therein.
