Typical Interior Partitions
Be clear: 'typical' and 'possible' are not
the same. What is 'typically' built may or
may not not be ideal, beautiful, or even
functional. 'Typical' means just that, it is
what is done most of the time.
'Possible' is where designers live;
designers explore the question "What if..."

Even so, it is useful to understand what is
'typically' built.
'GWB', 'Sheetrock', 'drywall', 'gyp board',
are all different ways of referring to
gypsum board, a flat panel product that is
used to make the surfaces of partitions
and ceilings.

gypsum board
gypsum boards are manufactured by
many different companies. USGypsum is
one such company. USG makes a
product that is called 'Sheetrock'. This istheir version of gypsum board.

The term 'Sheetrock' is a proprietary term;
that is, it is a proper name; the name of
USG's gypsum board.
Nevertheless, you may hear people refer
to 'sheetrock' as if this is the generic way
of referring to gypsum board; it is not.
The generic term is 'gypsum board.'

gypsum boards are produced in many
sizes and thicknesses:
4'x8', 4'x10', 4'x16'
thicknesses of: 1/4", 3/8", 1/2", 3/4",5/8",
a special product called 'shaftwall' is 1"
thick, and designed to be used to lineelevator shafts.

Gypsum Board
Gypsum board is the generic name for the group of products
comprised mainly of a noncombustible gypsum core and paper
facings.
Gypsum board is commonly referred to as drywall, wallboard, plasterboardand sheetrock. Gypsum is a mineral found in sedimentary rock formations.
This product is perfectly highly fire resistant.
Gypsum contains chemically combined water that is driven off as steam
when subjected to high heat, effectively fighting fire. Gypsum board is the
most common interior finish used today in Canada and the United States

Types of Gypsum Board
Regular- is used as a surface layer for walls
and ceilings, available in tapered and square
edges.
Type X - is available in -inch or 5/8-inch
thickness and has improved fire- resistance
through the use of fibers mixed within the
gypsum core.
-
7/29/2019 Lecture 606 Interior
11/68
Type C or Improved X - Additional additives
give this product improved fire-resistance.
Required in some fire-tested assemblies.
Water Resistant Board - made with a water-
resistant core and water-resistant face paper.
Also known as "green" board. Designed as a
ceramic tile backer board..

Gypsum Liner board - available in - or 1-inch
thickness and used primarily in area separation
wall systems.
Soffit board - designed for exterior use under
protected overhangs and walkways.
-

Gypsum sheathing - used as an
underlayment in exterior walls for
structural stability and fire-protection.
Available in treated and non-treated corefor water-resistance.

Joint Treatment
Gypsum wallboard produces a monolithic surface by
taping the depression formed along the edges of gypsum
board. The procedure is to embed a tape with a taping or
joint compound over the tapered joint. The depression is
then filled with successive layers of compound and
sanded to produce a monolithic surface. The square
edge of the gypsum panels that meet are often referred
to as "butt" joints and should be feathered out furtherthan tapered joints.

there are two wood framing systems:
platform framing & balloon framing
platform framing: vertical studs are only one story tall.
each separate story is framed individually, one vertical
level at a time. most wood frame buildings today are
built this way.
balloon framing: vertical studs run the full vertical height
of the building. floor joists are 'let in' to notches in the
vertical studs. used mostly prior to 1940.

placed on the floor.

bricks
There are two basic brick types - face and
paver.
paver bricks are used for patios, driveways, et
cetera. paver bricks are usually 4" x 8" x 2"
face bricks are typically used to build walls. face
bricks are made in a range of sizes, but the mostcommon construction brick size is 3 5/8" x 2 1/4"
x 7 5/8"

The most common brick wall used in
building houses is a "veneered wall".
Facing brick is placed outside the frame of
the house and the brick veneer is attached
to the frame by metal ties or by grouting it
to mesh attached to studs.
-
7/29/2019 Lecture 606 Interior
36/68
The other common type of wall used in
houses is a solid masonry "bearing wall",
which means that the wall carries the
weight of the house. With this type of wall,there is no frame behind the brick. Instead,
the brick, and usually a "back up" of hollow
masonry units or brick, provide bothenclosure and structural system.
-
7/29/2019 Lecture 606 Interior
37/68
In some cases, a house may have a brick
"cavity wall" (which is frequently a bearing
wall as well).
This is a wall in which a space is left between an outer
and an inner width of brick. The space is usually filled
with insulation. Most often, this type of wall is used when
it is desirable to have an exposed brick interior wall.However, exposed brick interiors can be constructed
using inside veneered or bearing walls.

There are three categories ofstone:
1) Igneous: solidified directly from the molten state, thisis the hardest and least porous stone.
2) Sedimentary: sand and decomposed material carried
by water, and settled, this is the softest and most porousstone.
3) Metamorphic: sedimentary materials which are further
hardened by a combination of pressure, heat, and
moisture, close in hardness compared with igneous
stone.
-
7/29/2019 Lecture 606 Interior

stone used in construction (of a building,
or a garden wall) may be divided into
three classes:
rubble
ashlar
trimmings
-
7/29/2019 Lecture 606 Interior
44/68
rubble
Rubblework: consists of stones in which
the adjoining sides are not required to be
at right angles. It is used for rough
masonry, as in foundations, backing, etc.,and frequently consists of common field
stone, roughly dressed

rubble
Field-Stone Walls. Walls of this kind are
built of small, uncut stones, and are
frequently employed for fences and rustic-
house work. Such walls should be madequite thick on account of the round and
unstable shape of the stones used in their
construction.

ashlar
Ashlar:
Stonework that is cut on four sides so that
the adjoining sides will be at right angles
to each other, is known as ashlar, no
matter whether the face is dressed or not.

1) Granite: Igneous, extremely hard
(and non-porous), used commonly as veneer.
2) Limestone, Sandstone: sedimentary stones that differ based on their
composition, they are soft, fairly porous, easily worked, and are used both as a
veneer and as structural material.
3) Marble: metamorphic, harder than limestone or sandstone, and more durable,
still fairly easily worked. Mostly a decorative material
4) Slate: metamorphic, a smooth, dark, waterproof material used frequently in floors,
and as shingles.
5) Travertine: sedimentary, a soft porous stone used decoratively in interior uses only.
6) Soapstone: sedimentary, used for counters.

such as clay is used to keep the stones together. A typical wall consists of a
foundation course, generally of larger stones or boulders known as footings,
with two wall faces of large stones. The cavity in between the faces is filled with
smaller stones or hearting.

stone veneer
Stone Veneer Although stone is too
expensive in general for structural
purposes, because of its durability it can
be effectively used for surfaceapplications.
Choice of stone is determined by color,texture, desired hardness, and weight,
with a multitude of options available.

Applications of stone veneers:
1) Interior: as a wall or floor covering,
generally for public area like lobbies,corridors.
2) Exterior: as a cladding, for the base, forspandrel panels, or for the entire building

Finish of stone masonry
1) Roughed: the outer surface of the stone may be cut in
such a way that it looks uncut. This treatment is
commonly found at the base of a building (such as this
one).
2) Rustication: grooves are left at the edges of the stones
to provide extra definition of the joints. Traditionally this
is used as a transition between the roughed stone and
the smooth stone.
3) Smooth: there are a number of finished that can be
applied to relatively smooth stones, depending on the
device used.
