This crown moulding is basic in form. It has the classic appearance of wood millwork, but it is crafted in urethane, one of our most versatile materials. When it comes to trim and moulding, urethane crown moulding offers a durable and cost-effective solution. It installs with ease and provides subtle ornamentation for the wall and ceiling. Urethane crown moulding is pre-primed and ready for finishing. Ogee moulding is a double-curve moulding style. This simply elegant profile is traditionally known as cyma recta. Ogee moulding may be enriched with ornamentation to various degrees, but it is always concave above and convex below. This creates a beautiful transition between wall and ceiling.
