The building materials context.
Building materials manufacturing covers factory-made products used to build America's homes, commercial spaces, and infrastructure — cement, gypsum wallboard, roofing, siding, insulation, engineered wood, and architectural glass. These plants tend to serve regional markets, are highly capital-intensive relative to their headcount, and are closely tied to U.S. housing and construction cycles.
