What is the difference between the Cornice Board and the Valance Board?
The Cornice Board is a more structured, sometimes formal, window top treatment. It has a face board, dust board and two end boards. The Cornice Board is covered in fabric and is used with draperies, sheers, and vertical blinds. The Valance Board is a horizontal board (mounting board), without front and end boards. It is a more casual top treatment. Fabric is attached to the board and hangs free from the front and sides. The Valance Board is used with horizontal blinds, shades, and plain windows.
