Flat trim moulding is one of our most basic forms of urethane trim. It accents walls, windows, furniture, and more. Pre-primed, ready-to-install trim leads to quick and effective enhancements addressing all aspects of your decor. Flat trim moulding is non-porous and highly resistant to the effects of moisture. It will not warp, crack or decay, and so it performs exceptionally well in exterior applications. Flat trim moulding has the appearance of traditional wood millwork, but it is precision molded in high-density polyurethane, a rigid foam material. Urethane trim is strong and durable, but also lightweight and easy to work with.
