Floor Joists:
Parallel floor framing
members that support the sub floor, underlayment and flooring. Joists are
supported by larger beams, girders or
bearing walls.
Floor Plan:
Floor layout of house or
building.
Hardwood:
One of the botanical groups of
trees that has broad leaves in contrast to
the needle-like leaves of the conifers or
softwoods; hardwoods are (1) deciduous (shed
their leaves in the fall or at end of each
growing season), (2) have shorter length
wood fibers than softwoods, (3) contain
cells (vessels) of relatively large
diameters (in addition to the wood fibers)
and (4) have seeds enclosed by an ovary.
Kiln Dried: Wood seasoned in a kiln by
means of artificial heat, humidity and
circulation; “kiln dried” wood may refer to
wood with various moisture content
percentages.Lineal Foot:
Having length only; used in
designating quantities of mouldings, boards,
etc. (i.e. linear foot, or running foot;
“lineal” usually designates non-specified
lengths).
Moisture Content
: The amount of water,
usually expressed as a percentage of the
weight of oven-dry wood, contained in wood;
obtained by one or two methods, namely (1)
oven drying or (2) electric moisture meter.
Particleboard:
A formed panel consisting
of particles of wood flakes, shavings,
slivers, etc., bonded together with a
synthetic resin or other added binder; the
particles are classified by size, dried to a
uniform moisture content, mixed with binder,
mat-formed, compressed to density and then
cured under controlled heat and pressure.
Plywood:
A cross banded assembly of
layers of veneer or veneer in combination
with a lumber core or plies joined with an
adhesive; the grain of the adjoining veneer
or plies is approximately at right angles;
an odd number of plies is generally used.
Two primary types of plywood are recognized,
“veneer plywood” (layers of veneers only)
and “lumber core” plywood (lumber core with
veneers or plies bonded to it).
Softwood:
One of the botanical groups of
trees that has persistent needlelike or
scale like leaves; softwoods are evergreen
(only three important native species being
deciduous), have longer length fibers than
hardwoods, do not contain vessels and have
seeds naked; also known as “cone bearers” or
“conifers”.
Sub-Flooring:
The first layer of
oriented strand board, plywood or planks
laid over floor joists.
Take Off:
Figure price and specs of
materials for home or building from the
blueprints or plans of the project.
Tongue and groove joint:
A joint formed
by the insertion of the “tongue” of one wood
member into the “groove” of the other;
modifications include tongue and groove
rabbet joint, dado tongue and rabbet,
tongued shoulder joint, dado and rabbet
joint, dado and lip joint.
