Insulated masonry block

A masonry block comprising:

• pairs of spaced opposed side walls and spaced opposed web walls forming cavity means therebetween which is open at both ends;
• at least one of said web walls extending between terminal ends of said side walls and defining an outer peripheral portion of said blocks and
• a substantially rectangular insulative plate means of thermally insulative material disposed in said cavity means;
• said insulative plate means extending across said cavity means from one to another of said walls and terminating at said web walls;
• said insulative plate means including first and second side surfaces facing respective ones of said walls, each of said surfaces including:
• an upper portion spaced from its respective side wall so as to define an air cell therebetween extending from one to another of said web walls, and
• a lower portion, integrally connected with said one portion and flared downwardly and outwardly therefrom into at least engagement with said side wall surfaces to form an air barrier extending across the bottoms of said air cells from one to another of said web walls.

In a construction wall comprising a plurality of layers of masonry block laid atop one another and bonded together, each block comprising pairs of spaced opposed side walls and spaced opposed web walls forming cavity means therebetween which is open at both ends, at least one of said web walls extending between terminal ends of said side walls and defining an outer peripheral portion of said block, and substantially rectangular insulative plate means of thermally insulative material disposed in said cavity means and including essentially flat side faces which extend across said cavity means from one to another web wall and terminating at said web walls, the improvement wherein:

• said side walls each include:
• a portion spaced from a respective side face of said insulative plate means so as to define an air cell therebetween extending from one to another of said web walls,
• another portion projecting toward and at least substantially engaging said respective side face of said plate means to form an air barrier extending across said air cell from one to another of said web walls;
• and
• vertically adjoining blocks of said layers being bonded together by mortar joints disposed between vertically facing edges of said side and web walls and between vertically facing edges of said insulative plate means;
• each air cell defined by vertically adjacent air barriers being free of insulative material.
