An inflatable insulator covers an associated attic access hatch to prevent a transfer of heat from a first indoor environment maintaining temperature control and a second indoor environment not maintaining temperature control. The insulator includes at least one air chamber adapted to contain a volume of stationary air. Impermeable layers define the air chamber. Sidewalls extending from a generally planar top wall to remove the impermeable layers from a direct contact with the access hatch.
