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 …
WebUL Fire-Rated. Westbrook Block is a proud producer of Underwriters Laboratories® (UL®) Approved Fire-Rated CMU, both Light Weight and Normal Weight densities, in 2-, 3- and 4-hour configurations. Allowing for safe means of egress and a higher fire rating, these blocks should no longer be looked at as JUST standard grey CMU. WebBlocks are larger and lighter than traditional concrete masonry: Height: 8 inches typical; Width: 24 inches long; Thickness: 4, 6, 8, 10, and 12 inches; A standard 8-by-8-by-24 inch unit weighs about 33 pounds; Specialty shapes: U-shaped bond beam or lintel blocks are available in thicknesses of 8, 10, and 12 inches.
