A masonry block comprises pairs of spaced opposed side walls and spaced opposed web walls forming a cavity therebetween. An insulative plate of thermally insulative material is disposed within the cavity. The insulative plate extends across the cavity from one to another of the web walls. The side walls each include a portion spaced from the insulative plate so as to define an air cell therebetween extending from one to another of the web walls. The side walls each further include another portion projecting into engagement with the plate to form an air barrier extending across the air cell from one to another of the web walls. Upon forming a wall with such insulated blocks, the air cells are sealed-off from one another to limit convection within the wall.
