摘要

A masonry block unit having spaced, selectively removable, vertical flanges on its inner face which are so spaced that they may be laid in the same direction and overlapped corresponding to the spacing in order that alternate flanges will provide a continuous row for attaching cladding and between such rows standard insulation may be placed, with the removal of the flanges which do not fall in the continuous lines.
