An attic access assembly includes an outer frame and a panel subassembly. The outer frame attaches to a ceiling and frames an attic opening. The panel subassembly includes a central panel that fits within the outer frame, and a flexible barrier that defines an insulation pocket extending upwardly from the central panel. The central panel may include an insulating foam material. The insulation pocket is used to contain an insulating material. Weatherstripping seals the panel subassembly to the outer frame. The panel subassembly may include a panel frame that fits within the outer frame, frames the central panel, and defines a groove to retain a weatherstripping seal.
