Introduction To Trim

TRIM

Molded trim does have a functional side – it covers gaps, rough edges and transitions between building materials. But when skillfully laid out, it can do much more. Wide baseboards, wainscoting, picture molding, crown molding and false beams on ceilings all add architectural detail and a decorative touch that can't be achieved with paint or wallpaper.


Base Shoe Mold3.) Shoe mold is normally the last piece of floor-to-wall trim to be installed. It gives a finished look to the project.


Quarter Round4.) Quarter round is used in place of shoe mold on some projects. Some customers and builders think it lends to a more massive look. In some cases you must use it to allow for expansion of hardwood flooring.


Baseboard

5.) Baseboard is, as the term implies, trim that is mounted or installed at the base of the wall. Here are few of the many different styles available. The left column shows end profiles and the right column shows face profiles.


Wall Base6.) Again as the name implies, this trim is mounted or installed at the base or floor level. It is usually followed by shoe mold or quarter round.

Base Molding

Base is the wood molding that is attached to the bottom of the wall next to the floor. This base molding also goes against the casing in a 90 degree angle. The base molding generally is slightly thinner than the casing in order to allow for a better finished look.


Half Round Molding

7.) Half round molding is, as the name implies, 180 degrees or half round as shown on this slide. It comes standard from ½” to 3” in different species and can be special milled to larger sizes.


Cove & Corner Mold

8.) The left column shows different sizes of cove molding. The middle column shows Inside corner molding and the right column shows shoe molding. These moldings, like all other molding and trim, are available in many different species.


Crown Molding

9.) The four crown molds shown here are the classier, more expensive types available. These are available in many different species.

Crown is the wood molding that is attached to both the wall and the ceiling. The molding itself is attached at a 45º angle to both of these surfaces. It softens the 90º angle where the ceiling and wall meet. In general, a higher ceiling will require a wider crown molding than a lower ceiling. Since a crown molding is attached at an angle, it also requires more skilled cutting to install properly. Crowns can also be installed in layers, for example, with the decorative part of a base molding showing beneath a crown molding to add extra dimension to moldings. Crowns can also be used in mantles or over doors where a more elaborate look is warranted.


Crown Mold # 2

10.) Multi-component crown molding.As you can see, many different components can be combined to getan effect you are looking for. This assembly would normally be used in ahouse or building with very high ceilings.

This assembly is made up of five different components:

1. Crown Mold2. Filler flat stock3. Larger flat stock4. Cap or chair rail5. Larger flat filler.


Window Stool & Apron

11.) Typical modern window trimmedusing casing, stool and apron. The stool and casing side profiles are shown and their locations illustrated with arrows showing their installed location.


Casing

12.) Three typical casing are shownon this slide, the side and face profilesare provided. This material would be used to case or frame around windowsand doors and in other creative locations.

Casing is the wood molding that surrounds a door, or window opening, on the flat inside walls of a home. It covers both the edge of the drywall or plaster, and the edge of the jamb, giving a finished look to your opening.


Casing # 2

13.) Shown on this slide are fourvery custom, very expensive doorcasing and trim combinations. Thisis the area of expertise where the trim carpenter can shine, not to mention make mega bucks $$$


Casing # 314.) More designs in casing.if you can’t find what you want it can be custom milled for you. This milling is very expensive.


Door Stop

15.) The profile shown on this slide is a top view of a door unit. It shows where the stop would be installed. Door stops may be used on windows and other trim projects.

Door Stop: A door stop is the small piece of wood, usually 1 3/8" - 1 1/2" wide, that is attached to the door jambs on both sides and on top of the door. This strip of wood is where the door comes to rest when it is closed. It stops the door from moving any further, and also covers the gap that would otherwise appear between the door and the jambs.


Screen Stock

16.) The two screen doors on this slide show the screen stock in place.

Note:The number of spaces on any type doorIs called the number of lights. The door on the left would be a 15-light and the one on the right a 10-light. Screen stock is used to build lattice and other custom trim.


Framing Mold

17. Framing mold is used to build frames. It is also used in many other applications such as trimming cabinet doors, drawers. etc.
