Flat trim moulding accents walls, windows, doors, entryways, and more. This basic moulding strip offers the versatility needed to create the detailed enhancements that our customers envision. Flat trim moulding can be used to create simple accents, and it can be combined with additional trim products. Flat trim moulding is crafted in urethane, and it includes a natural grain texture and hue. It can be stained like wood with realistic results. As a wood alternative, faux wood urethane trim is lightweight, cost-effective and highly resistant to the effects of moisture. Urethane trim will not warp, split, decay or offer a food source to insects.
