Cornice Boxes

Cornice boxes add architectural interest and make the ceiling appear higher. Correctly positioned, they can fool the eye into thinking a window is larger than it really is, hide imperfections in a wall, or conceal the headrail of an under treatment. Additionally, a properly designed cornice box adds functionality by blocking light around the top edge and cornice of any window treatment; draperies, blinds, solar shades, and the list goes on.

In the 18th century, elaborate gilded or carved cornice boards topped fashionable windows. They were made of plaster or wood. Today, this style of top treatment is much simpler. Cornices are still considered a hard treatment, now are made of wood that is then painted, or padded and upholstered with fabric. They can be boxy, arched or shaped into scallops, or have squares or triangles cut into the bottom edge.
              

A cornice is a shallow, box-like structure, usually made of wood, which is fastened across the top of a window to conceal the drapery hardware.

Add at least 4” to rod face of under treatment to get the board face.

Lining

54” linings are available in inherently flame retardant 3 pass suede blackout material or inherently flame retardant polyester lining which covers the inside and the top of the cornice box.
