Molding (decorative)

For other uses, see molding.

Molding is a strip of material that has been dressed or planed on all four surfaces. One of the sides is often given a profile for decoration purposes. A molding is typically used as at a wall juncture where it serves to hide a gap.

A "sprung" molding is a strip that has beveled edges, allowing it to be mounted at an angle between two non-parallel planes (such as between a wall and a ceiling). Other types of molding are referred to as "plain".

Types

There are a variety of common moldings:

• Astragal — Attached to one of a pair of doors to serve as a stop for the other door. The two types are "T-Astragal" and "Flat Astragal". The later is primarily used for decorative purposes.
• Base Molding — Used at the junction of an interior wall and floor to protect the wall from impacts.
• Batten — A symmetrical molding that is placed across a joint where two parallel panels or boards meet.
• Bed Molding — A narrow molding used at the junction of a wall and ceiling. Bed moldings can be either sprung or plain.
• Casing — The trim for both sides of a window opening.
• Chair Rails — A molding placed part way up a wall to protect the surface from chairs. Primarily used now for decoration.
• Corner Guard — A molding used to protect the edge of the wall at an outside corner, or to cover a joint on an inside corner.
• Cove Molding — A concave-profile molding that is used at the junction of an interior wall and ceiling.
• Crown Molding — A wide, sprung molding that is used at the junction of an interior wall and ceiling.
• Drip Cap — This is placed over a door or window opening to prevent water from flowing under the siding or across the glass.
• Screen Molding — This is a small molding that is used to hide the area were a screen is attached to the frame.
