Masonry facing materials — most common choice Within masonry construction, which material is most commonly used specifically for ornamental facing on building exteriors and interiors?

Introduction / Context:
Masonry walls often include a facing wythe that provides the finished appearance and environmental protection. Selecting accurate terminology for that facing material matters for specifications, procurement, and detailing.

Given Data / Assumptions:

• The focus is on ornamental facing in masonry (brick-and-mortar construction).
• We compare common materials used as the visible facade.
• Regional practices can vary, but standard drafting terminology applies.

Concept / Approach:
Face brick is specifically manufactured and graded for appearance on exposed surfaces. It emphasizes color, texture, and dimensional uniformity suitable for ornamental facades. While natural stone is also used for facing, brick is generally the most common, economical, and widely specified ornamental facing in masonry construction. Clay tile is used for partitions or roofing systems, and aggregate refers to stone or gravel used within concrete or architectural precast, not typically called out alone as the masonry facing material.

Step-by-Step Solution:

Verification / Alternative check:
Review building codes and material standards: brick is categorized into “face” and “building” (or “common”) grades; the existence of a “face” classification underscores its role in ornamental facing applications.

Why Other Options Are Wrong:

• Clay tile: more common in interior partitions or roofing (terracotta tiles), not the standard facade term here.
• Natural stone: used for facing but less commonly than brick in many markets; the question asks for the most common.
• Aggregate: a concrete ingredient, not a finished facing unit by itself.

Common Pitfalls:

• Confusing stone veneer systems with masonry brick veneers; both exist, but brick is typically more prevalent.
• Assuming structural brick; many modern facades are veneer anchored to backup walls.

Final Answer:
Face brick
