Abstract
Abstract A building block having hollow cores therein with rigid insulating core panels inserted into each of the core cavities and having insulation sealing cap elements overlying said core panels and extending beyond the ends of the cores to overlie the masonry web portions formed between adjacent cavities and thereby form a continuous insulating sealing strip extending the full length of a block wall.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
118 words
In combination with a plurality of masonry building blocks having cavities formed therein and having masonry divider webs interposed between adjacent cavities, insulating barrier panels inserted into each cavity and constructed to define a cap-receiving groove in the upper portion thereof, a cap element with a portion thereof extending above each cavity and extending horizontally beyond each cavity to overlie a portion of each web and form with adjacent cap portions, a continuous barrier strip between adjacent rows of blocks while providing an insulating barrier within each block cavity, said cap element having a portion adapted to extend downward into the groove to produce a sealing retaining fit with the respective upper edges of said cavity barrier panels.
Claim 2
Dependent Claim
118 words
In combination with a plurality of masonry building blocks having cavities formed therein and having masonry divider webs interposed between adjacent cavities, insulating barrier panels inserted into each cavity and constructed to define a cap-receiving groove in the upper portion thereof, a cap element with a portion thereof extending above each cavity and extending horizontally beyond each cavity to overlie a portion of each web and form with adjacent cap portions, a continuous barrier strip between adjacent rows of blocks while providing an insulating barrier within each block cavity, said cap element having a portion adapted to extend downward into the groove to produce a sealing retaining fit with the respective upper edges of said cavity barrier panels.
Claim 3
Dependent Claim
48 words
The structure set forth in claim 1 wherein certain of said cavities are tapered and the insulating elements inserted therein are provided with a cooperating similar taper to facilitate wedging the panels into said cavities and thus retain the panels in predetermined insulating position within the respective cavities.
Claim 4
Dependent Claim
91 words
The structure set forth in claim 1 wherein each of the building blocks is provided with a recess at the ends thereof whereby end cavities are produced between adjacent abutting block ends, insulating barrier panels inserted into each of said end cavities with a cap portion extending above each end cavity and extending horizontally to overlie a portion of the adjacent webs and combine with adjacent cap portions to form a continuous barrier strip between adjacent rows of blocks while providing an insulating barrier within all cavities of said block row.
