An insulated building block having stackable half-bond symmetry. The block has a pair of block parts the inner surfaces of which are serpentine-shaped defined by overlapping projections alternately from the block parts. Insulation is sandwiched between the block parts. The projections have enlarged end portions for interlocking the insulation to the block parts. The portion of the serpentine pattern in one of the block halves, defined by a plane parallel to the end walls and midway therebetween, is a repeat of the portion of the serpentine pattern in the other of the block halves such that the blocks are stackable in a staggered half bond relation with alignment of the insulation in the stacked block halves. At least two pins on different axes each extending longitudinally of the block into at least one projection of each block part. For bonding the insulation to the block parts, bonding material is injected into at least one cavity in the insulation in contact with both the insulation and at least one of the block parts. A composite wall comprises such building block parts stacked in half-bond symmetry, a poured concrete sheet, and insulation material having the serpentine pattern between the block parts and the concrete sheet.
