Abstract
An insulating cover for an attic opening comprising a pair of telescoping male and female assemblies operable between a nested retracted position where they interengage and an extended position of a size to fit over the attic opening, each assembly comprising a top panel section, side panel sections depending from the top panel section and an end panel section along a closed end of the top panel section combined to form a hollow assembly and insulating material in the space of the hollow panel sections.
Claims6
An insulating cover for an attic opening comprising:
- a pair of male and female assemblies operable between a nested, retracted position whereby said male and female assemblies slidingly interengage with one another, to form an extended position of a size to fit over the attic opening;
- each said assembly comprising a hollow top panel section;
- hollow side panel sections depending from said top panel section;
- and a hollow end panel section along an end of said top panel section and connecting said side panel sections;
- and
- compressible insulating material within said hollow top, side and end panel sections of each said assembly whereby said interengagement of said assemblies to form said nested position substantially compresses said insulating material within said hollow top and side panels of said female assembly.
