Abstract: A multimode or multi-configuration insulation assembly includes a cover and a frame. The frame has a seal or gasket which may be oriented upwardly in a first configuration or oriented downwardly in a second configuration. In the first configuration, the insulation assembly defines an insulative 5-sided box. In the second configuration, the insulation assembly is a four-sided frame with a removable cover, which enables the four-sided frame to remain installed on the attic floor to act as a dam to hold back blown-in attic insulation when the cover is removed to permit ingress and egress to the attic through the opening formed in the attic floor.

Abstract: An insulating system comprises a cover and a generally rigid attic sealing member. The cover defines an interior chamber, and the interior chamber is filled with insulation. The cover further forms a cavity in the bottom of the cover, where the attic sealing member is received into the cavity. Together, the system raises the insulating value (R-value) of an area above an attic opening to a minimum R-value level required by many building codes. The cover may be filled with insulation through a slit or passage extending along the top of the cover.
