ing of laminate is a cellular product as
well. The coefficients of expansion and
contraction of most horizontal and vertical grades laminates are similar to those
of the medium density particleboard. An
assembly of HPDL and particleboard is
usually very stable.
Backer Sheets - All HPDL countertops which conform to the Architectural
Woodwork Standards now require a full
backer sheet on the underside of deck,
buildup, and back side of backsplashes.

Unless the component is very well constrained, it is almost always a bad idea
to put laminate of veneer core plywood
as a substrate. NEMA LD3-2005 states:
“Plywood . . . dimensional movement is
significantly different than high-pressure
laminate. This may result in potential
panel warpage, stress cracking, and open
seams.”
For HPDL Countertops the Default
Stipulation in the Standards is “Custom
Grade” unless otherwise specified. This
grade usually matches the casework upon
which it is mounted.
Core Materials - Substrates may be
veneer core plywood at wet areas or sink
tops only if the owner insists and is willing to accept telegraphing. Plywood core
must have a Type II adhesive.
A better choice is Particle Board,
especially the moisture resistant variety
with a 24-hour swell factor of 5% or less
and 24-hour water-absorption factor of
10% or less. This core must be used for
the entirety of the assembly, including
splashes. Not just the leg or run that
includes the sink.

High Relative Humidity
Selection - The AWS specifies that
HPDL shall be Standard or Post-forming
grade with a minimum thickness of .039
inch. Vertical grade is not allowed on
counters. Some plastic laminate manufacturers only offer 4x8 and 4x10 sizes This
will effect yields, and limit seam or joint
locations. Most laminates are available in
3, 4 and 5 foot widths and lengths up to
12 feet.
The Wilson House:
Ralph Wilson used his home in
Texas as a proving ground for his
company’s laminate products. A
short, informative video, hosted by
design historian Grace Jeffers, tells
of the remarkable design innovations preserved in this 1959 structure. In the 1950s laminates were
used primarily for counter and table
tops. The Wilson House showcased
laminate clad casework and wall
paneling for the first time. View the
