Abstract:
1. An insulator for insulating an attic access hatch, comprising: an inflatable body including: a first flexible layer spaced apart from a second flexible layer and forming a chamber situated between the first and second flexible layers for containing a volume of stationary air, the first and second flexible layers situated between third and fourth protective layers covering at least a portion of outer oriented surfaces of the first and second flexible layers, a rigidity of the third and fourth layers protecting the first and second flexible layers from a puncture; a polygonal and planar first wall defined by the first and second layers and being larger than an associated access hatch; sidewalls defined by the first and second layers and extending downwardly from edges of the first wall, the sidewalls contacting an associated floor surface beyond a perimeter of the associated access hatch and removing the first wall from a direct contact with a frame defining the associated access hatch; a connector operative for pulling the insulator toward the associated floor surface and being connected to one of the third and fourth layers; wherein the chamber insulates the associated access hatch from transferring heat between a non-temperature controlled space and a temperature controlled space.
