This cove moulding profile is basic and form and sure to inspire trim enhancements ranging from bold to minimal in design. Cove moulding, which is also known as cavetto moulding, derives its name from its concave shape. This shape is often used in the crafting of crown moulding because it creates a smooth transition between wall and ceiling. Cove moulding is part of our urethane trim selection. Urethane molds with the great detail and depth that makes it a modern favorite. Urethane millwork has a classic appearance and high performance characteristics that lead to installations without frequent maintenance. Urethane cove moulding will not peel or decay and it is pre-primed.
