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

Quarter Round
4.) 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 Base
6.) 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 get
an effect you are looking for. This
assembly would normally be used in a
house or building with very high ceilings.
This assembly is made up of five
different components:
1. Crown Mold
2. Filler flat stock
3. Larger flat stock
4. Cap or chair rail
5. Larger flat filler.

using 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 shown
on this slide, the side and face profiles
are provided. This material would be
used to case or frame around windows
and 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 four
very custom, very expensive door
casing and trim combinations. This
is the area of expertise where the
trim carpenter can shine, not to
mention make mega bucks $$$

Casing # 3
14.) 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 door
Is 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.

doors, drawers. etc.
