Crown molding: A decorative capping that defines the space between ceiling and wall. It is installed at an angle so that it attaches to both surfaces.
Cornices: The very top portion of the crown molding. Cornice and crown molding work together to create the trim's profile.
Cove molding: Similar to crown molding, but where the profile of crown molding bends outward, cove molding shows a concave profile.
Chair rail molding: Created to protect walls from damage from chair backs. this molding dissects the wall about 3 feet above the floor.
Panel molding: Resembles a series of large empty frames placed above chair height or stretching from floor to ceiling.
Baseboard: Serves to protect the bottoms of walls from damage and acts as a connector for the wall and flooring. Shoe molding is sometimes installed at the bottom of the baseboard to hide any irregularities in the line of the floor.
