This basic moulding strip trims windows, doors, walls and more. Its simple design offers versatility as applied to a full range of enhancement projects. Flat trim moulding is crafted in urethane. Urethane offers high-performance and low maintenance in both interior and exterior applications. Urethane trim is precision molded and pre-primed. The non-porous nature of urethane prevents the moisture absorption that can damage wood. Urethane trim will not warp, splinter or decay. It is easy to work with and offers an alternative to wood. Our urethane trim products also blend well with existing trim and materials.
