Hollow brick providing thermal insulation

摘要

The hollow brick providing thermal insulation is a construction block having a relatively high R-value. The hollow brick providing thermal insulation includes a main brick body forming a substantially rectangular prism. The main brick body has opposed upper and lower surfaces, a pair of laterally opposed sidewalls and a pair of longitudinally opposed sidewalls. A plurality of open passages are formed through the main brick body and extend between the upper and lower surfaces thereof. Each open passage defines upper and lower open ends formed through the upper and lower surfaces. The plurality of open passages are arrayed to form a plurality of laterally extending rows and a plurality of longitudinally extending columns. A longitudinal thickness between adjacent ones of the open passages in each longitudinally extending column is greater than a lateral thickness between adjacent ones of the open passages in each laterally extending row.
