All types of coving, including cornices, are useful for ornamenting rooms and buildings. A plaster cornice is particularly appropriate when restoring an older building or when mimicking an antique architectural style.
Plaster has much to recommend it as a construction material. It is sturdy and tends to dampen noise. It is also useful in rooms with peculiar dimensions, as plasterwork is normally done by hand and can be more easily adapted to a particular space. A plaster cornice shares these advantages and is a natural choice in a room where the walls are finished in plaster.
nstallation of plaster remains the province of skilled professionals but is less time-consuming than it once was. Templates for common types of cornices and other decorative feature are widely available. These foam templates can be quickly and securely glued in place, and then covered with a thin top coat of plaster in much less time than it would once have taken to build an entire section of plaster cornice. More elaborate and decorative varieties of plaster cornice can be purchased in pre-fabricated sections, or assembled quickly from factory-made component pieces.
One of the primary uses of coving is to tie together the walls and ceiling of a given room. Any variety of molding or cornice can serve this function, but there are situations in which a plaster cornice is a particularly good choice. A room finished in plaster is a particularly good candidate for a cornice made of the same material in order to preserve a single style throughout the room.
