The type of facing brick known for being irregular and selected for architectural effects is indeed classified as FBA. This classification indicates that these bricks can have a variety of textures, colors, and sizes, allowing for flexibility and creativity in design. Architects and designers often choose FBA bricks specifically for their aesthetic qualities, which contribute to unique surface appearances and architectural detailing.

In contrast, FBX bricks are manufactured to strict dimensional tolerances and are typically used for applications requiring a more uniform appearance. FBS bricks, while still suitable for facing, offer a standard finish and uniformity that may not provide the desired visual variation. MW refers to modular bricks, which are used in a more structured and standardized setting, often in construction that prioritizes functionality over unique artistic design. Therefore, the choice of FBA bricks aligns with the need for irregularities that enhance the architectural character of a project.
