Astragal:              This moulding includes two different types, a T-Astragal and a Flat Astragal.  The “T” is attached to one of a pair of doors, which in classic Greek architecture was a bead around a column below the cap, is used for decorative purposes.           

Back Band:                  A rabbeted moulding used to surround the outside edge of casing.

Base:                   Applied where floor and walls meet, forming a visual foundation.  Protects walls from kicks, bumps, furniture and cleaning tools.  Base may be referred to as one, two, or three member.  The base shoe and base cap are used to conceal uneven floor and wall junctions.

Base Cap:           A decorative member installed flush against the wall and the top of a S4S baseboard.  Also a versatile panel moulding.

Base Shoe:          Applied where base moulding meets the floor.  Protects base moulding from damage by cleaning tools.  Conceals any uneven lines or cracks where base meets the floor.

Batten:                A symmetrical pattern used to conceal the line where two parallel boards or panels meet.

Casing:                         Used to trim inside and outside door and window openings.

Brick Mould:       Is used as exterior door and window casing.  It is a thick moulding, providing a surface for brick or other siding to butt against.

Chair Rail:           An interior moulding usually applied about one third the distance from the floor, paralleling the base moulding and encircling the perimeter of a room.  Originally used to prevent chairs from marring walls.  Used today as a decorative element or a divider between different wall coverings, such as wallpaper and paint or wainscoting.  A key decorative detail in traditional and colonial design.

Corner Guard:     Outside corner guard is used to protect corners or the ragged edge where wallcovering and painted surfaces meet an outside corner.  Inside corner guard covers uneven joints or ragged lines where wallpaper, paneling or other covering materials meets with painted or contrasting surfaced walls at an inside corner.

Cove:                  A moulding with a concave profile used at corners, particularly as a ceiling cornice.  Small coves may be used as an inside corner guard.

Crowns/Beds:     Most often used where walls and ceiling meet.  Crown mouldings are used to cover larger angles.  Crowns are always “sprung” while beds are either “sprung” or plain.  A “sprung” moulding has the interior corner beveled off to better fit a right angle joint.

Drip Cap:            Applied over exterior window and door frames, this moulding keeps water from seeping under the siding, also directs water away from window glass.  Makes an attractive contemporary interior door and window casing.

Hand Rail:                    Used as a hand support in a stairwell.

Glass Bead:         Also called glass stop, cove and bead, putty bead, glazing bead, and staff bead.  Used to hold glass in place.

Lattice:                Originally used in trellis work, this small, plain S4S moulding is among the most versatile of profiles.
