Abstract
An insulating cover is adapted for sealing an attic access panel. The insulating cover includes a substantially rectangular fabric layer and at least one rod for raising the fabric layer above the attic access panel. A cavity is defined by the fabric layer and is adapted to contain a volume of stationary air. A seal is formed around a perimeter of the fabric layer. The seal includes multiple fiber strands of material that are adapted to conform to a shape of a floor surface. The fiber strands are adapted to seal gaps formed where the cover meets the floor surface.
