WebMay 16, 2024 · Concrete Block (CMU) Sizes. Concrete Masonry Units (CMUs) are manufactured in a variety of sizes. They are identified by their depth – i.e. the thickness of the wall they create. For instance, a 6" CMU is nominally 6" deep while a 10" CMU is nominally 10" deep. Concrete blocks also come in half-sizes, which are helpful in … new toyota clearance saleWebFor concrete block walls, determine the U-factor from Table A3.1-3 based on the block size, concrete density, degree of grouting in the cells, and whether the cells are insulated.
