Insulated cementaceous building block system and blocks

Abstract

A concrete building block for masonry block walls is formed with first, second and third spaced rectangular face shells, where the second face shell is intermediate the first and third face shells. First and second cross webs connect the first and second face shells and a third cross web connects the second and third face shells. Insulating cores include end protrusions extending outwardly at the top edge thereof to fit into notches of the cross webs and include cutouts to accommodate mortar crumbs. The insulating cores further mate, creating an overlap that serves to (i) insulate against temperature transfer and (ii) provide a sound barrier. A unique block permits a combination of insulating inserts and solid grouting as well as a symmetric arrangement.
