1. Beading & Moulding

2. What are mouldings and beadings?
•Mouldings and beadings are contoured
strips of material used at two
intersecting surfaces.
•They are used cover transitions from
one type of material to another or
between surfaces that meet
perpendicular to each other, like walls
to ceilings or floors.
•They are usually made of timber,
plaster, or aluminium.

3. Profiles
The shape of beading or
moulding is called its profile.
Profiles can either be
standard (bought off the
shelf) or custom (made to
order).
Larger profiles are generally
referred to as moulding and
smaller ones are called
beading. Beadings are
typically smaller than 19mm.
Most beading and moulding
has a contoured face and a
groove in the back to prevent
warping.
The back edge is also slightly
bevelled towards the warp
groove so that the moulding
will sit flush at the top and
bottom edges.

4. Square-edge
Even though it is commonly
rectangular, moulding and beading
is called square-edge because of
the square corners compared to
other mouldings.
It is commonly used as infill
panelling and smaller sizes are used
as cover strips.
Recently, square edge moulding has
become popular as skirting.

5. Bull nosed & Pencil Round
Bull nose moulding is rectangular
moulding with a rounded edge.
The curve of the rounded edge is
calculated by using the thickness of
the stock as the radius of the curve.
Pencil round is similar to bullnose
except the radius of the curve is
much smaller.

6. Splayed, half splayed & bevelled
Splayed moulding is roughly 2/3rds
thinner at the top than the base.
Half splay is more common, where
the bottom is flat and the upper
half or third is splayed.
Splays can be combined with other
profiles like bullnose or pencil
round.
Bevelled moulding is rectangular
with a slight (aprox. 22.5ᵒ) bevel at
the top. Like a very small splay.

7. Colonial & Lambs Tongue
Colonial & lambs tongue moulding
are heritage profiles that match
older building aesthetics.
Lambs tongue has a small groove
before a pronounced bulge that
falls away. Similar to the shape of a
lambs tongue.
Colonial is very similar but has a
exaggerated hollow before the first
bulge and can have another groove
inside the curve.

8. Quad, Scotia and Ovolo
Quad is 1 quadrant or ¼ of a circle. It is usually found
on eaves or internal corners.
Scotia is a concave shape almost the opposite of quad
except for the square edges. It is commonly used to
bridge gap between existing skirting and new floors.
Ovalo is similar to quad with a square detail at each
edge.
Ogee is a combination of scotia and ovalo to create a
concave and convex section on the same profile.

9. Specialty moulding
•Flat/cover strip – Covers gaps
between materials
•Nosing – used under windows and
doubles as a shelf
•Splay beading – Used to hold glass
into window frames.
•Picture rail – a style of profile
shaped to allow traditional style
picture hooks.
•Dado/chair rail - A style of profile
that protrudes further to stop
chairs damaging wall linings.

10. Moulding locations
•Crown moulding –
Between ceiling
and wall or above
cabinetry
•Architrave –
framing an
opening like a
door or window.
•Dado – 1/3rd or ½ of
wall height.
•Skirting – Between
wall and floor
You may use the same profile of moulding in different places.
To communicate which one we mean we use the industry terms.

11. Lining and moulding
Traditionally moulding was used
with lining panels to create ornate
wall linings.
If these mouldings protruded from
the wall they were called bolection
moulding
Otherwise they were called panel
mouldings
