ABSTRACT:
A collapsible cellular insulation panel for use with mobile shelters is provided. The panel comprises first and second outer sheets with a plurality of intermediate thin flexible membranes. The membranes are secured along first and second edges to inner surfaces of the outer sheets. The membranes are attached to adjacent membranes along strips that are parallel to and intermediate the first and second membrane edges. The interconnected membranes form cells that trap insulating air and break up convective currents between the outer sheets. Supported from underneath on a horizontal surface, the membranes lay substantially flat, such that a thickness of the panel substantially equals the sum of the thicknesses of the membranes and outer sheets. The panel is thus well adapted for use with mobile shelters, because it occupies little volume in the collapsed state. A shear stress on the insulation sheet in a direction perpendicular to the first and second membrane edges opens the cells and increases a distance between the outer sheets. The insulation sheet similarly opens when suspended from above in a substantially horizontal configuration.
