The work that a carpenter does can vary greatly from one job site to the next. While some work primarily with wood, others also install insulation, drywall, and even windows. There are three primary divisions of carpenters: residential, commercial, and industrial.
Residential carpenters usually specialize in individual home construction. Commercial carpenters typically work in business environments where they construct offices and other public buildings. Industrial carpenters may work on large city buildings by constructing the scaffolding and supports for metal-workers and other construction workers.
