Molding & Casing

Molding and casing is considered finish carpentry. It is a decorative feature of woodwork that also serves a functional purpose, that of a transition between two surfaces such as a wall and floor, a wall and ceiling, or a window or doorframe and the wall. Moldings and casings also indicate a termination point. A good example of this is the use of the rosette that marks the intersection and corner of two pieces of casing on a door.

Molding and Casing Materials

Typically, moldings and casings are made from wood or plaster. The type of wood used to make molding and casing depends on whether it is to be painted or not. Pine or birch is recommended for moldings and casings that will be painted, whereas red or white oak, ash, and pine are recommended for moldings and casings that will be stained or not painted. However, moldings and casings might also be made from a plastic composite material or resin.

Moldings and casings have a profile that is usually both concave and convex. The profile is created by means of a router or a laser on the front face of the wood surface. The back of the molding or casing is either flat or in the shape of an L to conform to an existing edge such as a baseboard. Casing is typically 2 1/2-inches by ��-inch, whereas the size of moldings varies according to type.
