Are you interested in a durable and versatile alternative to wood? Our urethane millwork offers a world of possibilities. Flat trim moulding strips are precision molded in high-density polyurethane. This rigid material is strong, but lightweight, with a feel similar to that of pinewood. Flat trim moulding is suitable for use in both interior projects, as well as in exterior applications, where it resists the warping, cracking and decay that can damage wood mouldings. Urethane moulding is non-porous and enduring. All trim strips are pre-primed and they hold paint well.
