PANEL & SYSTEM
DESCRIPTION
PRODUCT NAME:
Panel 20®
Prefinished Architectural Panels
OVERVIEW:
Panel 20® is a composite panel for
exterior use made by laminating an
aluminum skin to a substrate of
thermoset phenolic resin. A second
aluminum skin is added as a backer
and provides thermal stability and
panel balance.
Panels are furnished with a
strippable film (or interleafed
microfoam) on the painted surfaces
to protect the finish during shipment
and installation. Panel 20® is attached to the substrate
using construction adhesive in
the field of the panel and mechanical
fasteners around the perimeter. The
system is completed using two piece
(plastic receiver and extruded
aluminum cover) trim moldings
available in both batten and reveal
(1/2”) profiles.
BASIC USES & APPLICATIONS:
As an alternative/complement to
other building materials such as brick
or stucco, Panel 20® is designed for
general use as an exterior cladding
on walls, canopies, fascias and
accent bands.
Panel 20® is typically used on low
and medium rise buildings such as
schools, banks, office parks, medical
facilities, retail identity programs,
etc... However, with a durable
thermoset phenolic core and a
smooth finish, Panel 20® is also ideal
for other applications where a high
end system look is desired.
GENERAL LIMITATIONS:
Panel 20® is intended for use as
exterior cladding. It is not elgible for
use as a structural element of a wall
assembly. Panel 20® should not be
used in applications where the slope
exceeds 25° from vertical.
SYSTEM FINISHES:
Panel 20® comes standard with a
smooth aluminum skin. Textured
skins are not available.
Standard and metallic colors are
furnished with a durable Kynar 500®
coating. Anodized finishes are
available as a standard finish.
Panels can also be ordered with
premium and custom colors to match
customer’s standard.
Moldings are coated using a
Kynar 500® paint system and can be
painted to match any standard or
custom color.
INSTALLATION
OVERVIEW
CONCEALED FASTENERS:
Attached to the substrate with
concealed screws, Panel 20® offers
two piece aluminum moldings to
complete the panel joints. These
moldings (available in batten and
reveal profiles) consist of a plastic
receiver attached prior to the panel,
then finished with a prepainted cover
to match or complement the panel.
In addition to perimeter fastening,
Panel 20® should be adhered to the
substrate in the field of the panel.
Installation is non-progressive when
using these moldings allowing panels
to be removed and replaced should
damage occur.

FEATURES & BENEFITS:
As a complete exterior cladding system, Panel 20® offers a number of
benefits to the building owner, architect, and installer including:
System Look w/o Fabrication
Panel 20® offers a high-end
appearance without the additional
costs associated with fabrication
by using trim moldings (with flat
batten or reveal profiles) and
concealed fasteners.
.
- Curveable
With a durable and thermally
stable core, Panel 20® (and
moldings) can be formed to form
graceful, clean curves.
Easy Installation
Simple sheets/trim concept easy to
understand. Non-progressive
sequence also allows for removal
or replacement of panels which
may become damaged.
Color Matched Moldings
Several different profiles (including
reveal and batten) to complete
the system look. Moldings can
be matched or painted a comple-
mentary color for emphasis.
Low Maintenance
Most foreign matter can be cleaned
from surface with mild detergents;
can be incorporated into yearly
building washing schedule.
Economical
With material and installation
savings, Panel 20® provides a
high-end appearance and an
economical solution when
compared to fabricated systems.
