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.

An access door assembly is for a floor structure. The access door assembly includes a door frame coupled to the floor structure and defining an opening aligned with a staircase, and an access door within the opening and having first and second longitudinal sides. The first longitudinal side defines a first opposing bevelled surface, and the floor structure adjacent the opening defines a second opposing bevelled surface. The access door assembly also includes an arm coupled to the access door and configured to pivot the access door between an open state and a closed state. The first and second opposing bevelled surfaces are aligned and abutting in the closed state, and are in spaced apart relation in the open state.

A secure box assembly for a floor structure may include a frame body coupled between joists within the floor structure and defining a cavity therein, an uppermost portion of the frame body being aligned with an upper surface of the floor structure. The secure box assembly may also include a door having a first major surface facing the cavity of the frame body and a second major surface opposite the first major surface, a hinge assembly coupled between the frame body and the first major surface, and a powered arm coupled between the frame body and the first major surface and configured to pivot the door between an open state and a closed state. The door may be flat and flush with the upper surface of the floor structure in the closed state.
