Cast in molds rather than milled, polyurethane trim can reproduce highly ornate, deep-relief profiles that would be costly to run in solid wood. It's dense but lightweight, resists dents, and ships with pre-mitered inside/outside corner blocks that eliminate coping entirely — a favorite for DIYers who want an elaborate look without the joinery.

Best for: formal rooms wanting an elaborate, oversized profile, or DIYers who want to skip coping altogether using corner blocks.
