Claim:
An insulating cover assembly in combination with an existing attic access, the combination comprising: an existing attic access having a surrounding structure integral to a ceiling of a building and providing access to said building's attic, said existing attic access defining an existing attic access opening therethrough and having an existing trap door for closing said existing attic access opening; an insulating cover placed on said surrounding structure and including: a continuous frame having spaced side walls and spaced end walls and which frame is formed of a free standing insulating material having an upper surface and a lower surface, said frame defining a frame opening therethrough, said frame opening being aligned with said existing attic access opening, said frame being of a size and configuration so as to enclose said existing attic access opening when said lower surface is supported on said surrounding structure; and a removable closure member formed of a free standing insulating material, said removable closure member not being bonded to any portion of said continuous frame and said removable closure member including: a depending central portion, said depending central portion being sized and shaped to fit within said frame opening defined by said frame and fictionally and snugly engage each of said side walls and said end walls of said frame inside said frame opening to create a first continuous seal with said frame when said removable closure member is positioned on said frame in a covering relationship with respect to said frame opening; and an upper portion forming flanges, said flanges extending laterally outward relative to said depending central portion, said flanges being sized and shaped to frictionally and snugly engage an upper surface of each of said side walls and end walls of said frame to create a second continuous seal with said frame when said removable closure member is positioned on said frame in covering relationship with respect to said opening defined by said frame; wherein said closure member is not hinged to and detaches from said frame when said first continuous seal and said second continuous seal are broken by a force applied to said removable closure member through said frame opening, leaving said frame enclosing said existing attic access opening; and wherein said first seal and said second seal are generally orthogonal to each other when said removable closure member is positioned on said frame in covering relationship with respect to said opening defined by said frame.
