The comb face pattern is unique, as it is slightly irregular in the spacing of the vertical striations. Deep Score units must be manufactured in a wider block width, to allow for the deep score to be achieved, while maintaining the minimum required face shell thickness. Deep Scores, (also called “1-inch scores”) are 1” wide and 1” deep. Tapered scores are 3/4” wide, tapering to 3/8” wide, and are 5/8” deep. Standard scores are typically 3/8” wide and 3/8” deep (emulating a typical mortared head joint). Scores are available as “STANDARD”, “TAPERED”, and “DEEP SCORE”. Scored units may also be available in 1, 2, 3, 5, 7 and 11 scores per unit. For example, an 8 x 8 x 16 unit with a single score up the middle of the face, looks like two 8” long units, rather than one 16” long unit, whereas an 8 x 8 x 16 unit with three scores, looks like four 4” long units are used. “Scored” units are available in a range of options, the most standard of which is intended to simulate a vertical mortar joint(s) on the face of the block, to appear as though there are several smaller sized units being used, while still allowing construction using full-sized units. Let's take a closer look at the available Pattern Options: Be sure to review the available pattern options in the specific region of your project, by contacting your local product expert for further clarification. There are a variety of pattern options available, yet some regional markets offer more than others. Until further advancements allow, be sure to specify textures as vertical.Consult your local product expert for more information on your available pattern options. Because of this, only vertical features can be cast into the block. CMU is made by pouring a mix design into a steel mold, which then uses a vertical motion to release the block from the mold. Patterns can be produced in the vertical direction of the block face, but are NOT available in a horizontal direction. You should note that there is a visible difference between a cast score or a cut score. Some scores can be "wheel cut", which means that rather than being cast into the block shape, they are cut into the face of a block after it is fully cured. Comb Face patter ns are produced by a mechanical come after the block is released from the mold. The score and flute patterns are typically cast into the block as part of the form. Most patterns (scores, deep scores, flutes, and combs) are part of the manufacturing process and accurate information must be developed early in the design stage. Here are the Top 3 issues that you should keep in mind when selecting a block pattern:
