An insulated building block (10) 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 (62) alternately from the block parts. Insulation (20) is sandwiched between the block parts. The projections have enlarged end portions (64) 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 (20) in the stacked block halves. At least two pins (116) on different axes each extends longitudinally of the block into at least one projection (62) of each block part. |
