Green Trim. Outwater says its 100% Recycled Cornice and Crown Mouldings are made entirely from reclaimed polystyrene but match the quality of moldings made from virgin polymers. The lineup includes more than 100 varieties of straight trim and corner details. Although suited to traditional cornice or crown applications, these mouldings are specially designed to house indirect lighting fixtures. Most of the offerings are available only in 8-foot lengths. Prices range from $4.40 to $10.80 per piece. Outwater Plastics Industries, 800/631-8375, outwater.com.
