Abstract:
A composite building unit comprising a pair of spaced brick-like elements, each having a plurality of recesses in an inwardly facing side thereof, and an intermediate insulating element having a plurality of projections extending outwardly from each of two opposed side faces thereof, the brick-like elements and the intermediate element being joined by a press fit with the projections of the intermediate element being received within the recesses of the brick-like elements to frictionally hold the elements together. The intermediate element is formed with a raised barrier portion extending along the top thereof and with an indentation extending along the bottom thereof to receive the barrier portion of another composite unit when stacked in mortar joint wall construction, the barrier portion acting as a dam to prevent the passage of water through the mortar joints and to channel the water to the ends of the unit for drainage to successively lower courses of masonry.
