CLASS DAY 10 - CHAPTER 7
INTERIOR FINISHES FOR
WOOD LIGHT FRAME CONSTRUCTION
Interior Construction Sequence
After the floor platform (concrete or wood) is
completed, and exterior walls, sheathing, roof
structure and decking is in place, the building is
“in the dry”, meaning if it rains one can still work
inside.
Interior Partition Framing is done simultaneously
with exterior walls if the building is wood frame.
If the building has masonry exterior walls, and/or
is steel frame, the interior framing does not
happen until the building is “in the dry.”

Materials
•Wood
•Sheet Metal
More Blocking
Metal shield to prevent nails
From being driven into
Plumbing pipes
Sealant around pipes to prevent smoke migration
From passing through wall space
THERMAL INSULATION
Purpose is to slow the
passage of heat flow
Common insulating
materials are spun glass
fibers and rock mineral
Installation is in
interstitial space between
outside & inside
R-Values are the
resistance to the number of
BTUs that will travel
through a material of given
area in a given time period.
Vapor Barrier installed
On warm side of insulation
Insulation in Interior Wall
Space to prevent sound
transmission
Exterior Wall
Vapor Barriers on Insulation
Insulation can be
purchased with or
without a vapor barrier.
The purpose is to
prevent condensation
from forming on
materials due to
moisture in the air and
temperature differential.
Materials are treated
paper, plastic, and
aluminum foil
Installation is always
on the warm side of the
insulation.
Radiant Barriers are used to reduce the flow of
solar heat from infrared and Ultraviolet radiation
by reflection.
Wall sheathing faced with white plastic or
aluminum foil on the outer surface reflect UVs and
Infrared.
Reflective barriers also include a material called
“house wrap”, which not only reflects but
provides a barrier to air infiltration due to wind.
Wall & Ceiling Finish
Ceilings:
Drywall, with textured and painted surface,
sometimes acoustic spray.
Plaster once was the norm, but now is rarely
used because of labor cost.
Walls:
Drywall, with a variety of attached material,
such as texture & paint, wallpaper, vinyl
fabric, paneling, tile.
GYPSUM DRYWALL - STACKED
Beveled
Joints
DRYWALL MATERIALS
Corner bead
Joint Compound
Joint Reinforcing Tape
Joint Tape Applied
Drywall Joints are first
taped
with a 2” wide paper made
for the purpose and set
smoothly into a water
soluble joint compound.
Taped joints are
“floated”
With a bedding
compound
And toweled smooth,
then
Sanded to conceal all
Applying Joint Compound
Sanding
INTERIOR DOORS
Decorative panel doors
are available in a variety
of natural wood, plastic,
or metal.
Flush type doors are
Available in a variety of
Natural wood veneers
or pressed wood, and are
Made with either a solid
Core or hollow core as
The need dictates.
Face Veneers
•Wood
•Laminate

Veneer supported
By cardboard or
Wood.

Install air supply registers and return air grilles
Thermostats and filters
RESILIENT FLOORING
Resilient flooring
is material such
as vinyl
composition tile,
vinyl tile, or sheet
vinyl.
It is a material
that must be
glued down at the
proper
temperature, then
protected from
construction
traffic.
WOOD FLOORING
Pre finished wood flooring is another material
that must be protected from construction
traffic.
Unfinished hardwood flooring can be
installed early, then finished as one of
the last steps.
Types of wood flooring include blind
nailed tongue &
grooved, square
edge, or wood
tiles such as parquet.
CARPET
Carpet is a final material that should
not be installed until last – for obvious
reasons.
There are two types of carpet, based
on the method of installation.
Stretch carpet is placed over a
resilient pad and held in place
with barbed strips fastened to
the floor.
So called, ‘commercial carpet’
is a very tight weave material,
and is installed with a mastic
adhesive troweled on the floor.
Many of the processes of finish within a project
overlap in the time frame in which they are installed.
But every consideration must be given and demanded
by the Architect to guard against damage of one
material for the sake of another.
Finish surfaces should never be done prior to other
trades that could cause damage, without adequate
protection to the materials.
The General Conditions of the Contract for any project
will state that damage done to adjacent finish shall be
paid for by the trade responsible for the damage.
