|
Base Shoe: |
A molding designed to be attached to base molding to cover
expansion space. |
|
Burl: |
A swirl or twist of the grain of the wood which usually occurs
near a knot, but does not contain a knot. |
| Checks: |
Longitudinal separation of the fibers in wood
that do not go through the whole cross section. Checks result
from tension stresses during the drying process. |
| Compression
Set: |
Caused when wood strips or parquet
slats absorb excess moisture and expand so much that the cells
along the edges of adjoining pieces in the floor are crushed.
This causes them to loose resiliency and creates cracks when
the floor returns to its normal moisture content. |
| Compressive Strength
Parallel to Grain: |
Maximum stress sustained by a compression
parallel-to-grain specimen having a ratio of length to least
dimension of less than 11. |
|
Compressive Stress Perpendicular to Grain: |
Reported as stress
at proportional limit. There is no clearly defined ultimate
stress for this property. |
|
Crook: |
The
distortion of a board in which there is a deviation, in a
direction perpendicular to the edge, from a straight line from
end to end of the piece. |
|
Cupping: |
A "concave" or "dished" appearance of individual strips, with
the edges raised above the center. |
|
Decay: |
The decomposition of wood by fungi. |
|
Density: |
Weight per unit volume. Density of wood is
influenced by rate of growth, percentage of late wood and in
individual pieces, the proportion of the heartwood.
Dimensional Stability: A term that describes whether a section
of wood will resist changes in volume with variation in
moisture content (other term: movement in performance). |
|
Distress: |
A heavy artificial texture in which the floor has been
scraped, scratched or gouged to give it a time worn antique
look. A common method of distressing is wire brushing. |
|
Eased Edge: |
The chamfered, or beveled edge, of
strip flooring, plank, block, and parquet at approximately 45
degree angle. |
|
End-Joint: |
The place where two pieces of flooring
are joined together end to end. |
|
End-Matched: |
In strip and plank flooring the ends
of individual pieces have a tongue milled on one end and a
groove milled on the opposite end, so that when the individual
strips or planks butted together, the tongue of one piece
engages the groove of the next piece. |
|
Equilibrium Moisture Content: |
The moisture content at which wood
neither gains nor loses moisture when surrounded by air at a
given relative humidity and temperature. |
| Figure: |
The pattern produced in a wood surface by annual
growth rings, rays, knots, deviations from regular grain, such
as interlocked and wavy, and irregular coloration. |
|
Filler: |
In wood working, any substance used to
fill the holes and irregularities in planed or sanded surfaces
to decrease the porosity of the surface before applying finish
coating. |
