“Millwork” is a term used to describe ready-made carpentry products designed for installation within buildings. In the past, millwork was crafted exclusively from wood. The majority of millwork is still wood-based, but some millwork products are now fabricated using plastics and composite elements. Buyers often purchase millwork unfinished, and customize it via painting or staining. Certain firms do specialize in custom finished millwork, however. The term is sometimes used interchangeably with “casework,” although casework typically refers to finished cabinetry.
Variations of millwork are practically limitless, and are designated by a multitude of industry-specific labels. With so many types of millwork, occasionally confusing one carpentry term for another becomes likely, if not inevitable. Below is a short glossary to help keep things straight.
