Panel
Construction Balance |
|
 |
|
To achieve balanced
construction, panels should be absolutely symmetrical from the
center line, i.e., the panel must be of an odd number in
construction and the face and back should be of the same
thickness and species to allow expansion and contraction at
the same rate. This type of panel construction will
insure more stability. |
|
General Rules:
The thinner the facing material, the less force it can
generate to cause warping. The thicker the substrate,
the more it can resist a warping movement or force. MDF
and particleboard are the most stable cores. |

Book Match |
| Every other
"leaf" is turned over as if they were facing pages in a book.
The figures always match at the joints. |

Slip Match |
|
Consecutive leaves are slipped out one side by side.
There is no grain match at joints. Slip matching is the
architectural choice for straight grained "rift" veneers. |
|
|
Random Match (Not Illustrated) |
|
A
random selection of individual pieces of veneer from one or
more logs. Random matching produces a "board like"
appearance. This type of veneering is used in V-Grooved
wall paneling...seldom required in present markets. |

Sequence Matched & Numbered
(SM&N) |
|
Generally grades of plywood are laid-up with regard to
matching the veneer within the panel but there is no regard as
to whether the faces of one panel match the faces of another.
However, For what is termed "architectural grade plywood", the
panels are manufactured from the same flitch and kept in
flitch order as they are laid up. Panels are manufactured,
usually as 4' x 8' or 4' x 10', using the veneers in the same
sequence as they came off the log. The term for this is
"sequence matching". |
| A sequence of
face veneers may consist of as few as two up to as many as
twenty panels or more. Sequenced panels numbered for ease of
identification when being installed. Such panels are sold as
"Sequence Matched &. Numbered." |
