A method for making the core of a door of autoclaved aerated concrete (AAC). A billet of AAC is provided from which slabs are cut to the approximate dimensions of the door core. A reinforcing band is secured about the perimeter of a slab or a pair of slabs sandwiching a reinforcing panel. The thickness of the slab, or the pair of slabs and reinforcing panel, is then sized for the door core as by sanding. The door is finished by applying skins to the core surfaces and trim to the reinforcing band.
