(54) Improved insulated building block


(57) An improved masonry building block has rectangular side walls and a pair of connecting arms spaced from each other and from the ends of the block. The arms are notched adjacent one side wall to receive an insulating insert. A rectangular insulating insert has cooperating notches which receive the arms with portions of the insert disposed in the arm notches. Both the block side walls and the insert have marginal flanges which overlap and interlock with contiguous blocks and inserts in a composite wall structure. A multi-part insert is provided and has a first position where it resides within the block for transport and a second position where it projects into overlapping relationship with a subadjacent insert.
