Flat trim moulding has the look of wood millwork, but it is precision molded in high-density urethane, one of today's most versatile decorative materials. Urethane possesses a unique closed cell structure that locks out moisture. This prevents the warping, splintering, mildew and rotting that can plague some wood mouldings. The high-performance and low maintenance characteristics of our urethane mouldings just can't be beat. At Architectural Depot, we are your source for moulding products both ornate and basic. Flat trim moulding becomes a versatile addition to a variety of projects. It can be installed like wood and it is pre-primed.
