White - 1000 SOS is an opalescent, translucent
white panel. Used as a lighting diffuser or translucent
architectural panel, casts diffused, glare free light.
White varieties for sign and display applications include:
White 1020, a translucent sign white commonly
used as a sign background for signs illuminated with high-output
White 2020, offering similar diffusion in
thinner gauge (.045" and .060") for smaller signs, displays and
illuminated advertising panels.
White 1040, a bright white opaque panel
suitable for sign and architectural applications. White 1040
panels are available smooth both sides or pebbled on one side
(refer to White 1040-POS)
Standard Colors: Ten standard sign colors are
available, including translucent ivory, bright translucent
colors, a deep translucent blue, opaque browns and black.

panels are used in glazing and partition applications requiring
high light transmission and superior impact strength. These
near-clear panels are supplied with a micrograin gloss finish on
both sides, or with a matte or pebbled surface on one side
(refer to Crystal II-SOS and Crystal

medium-reflectivity surface with a slight texture that

By embedding various materials into the panel when casting
reinforced acrylic-modified polyester panels, new vistas are
opened to the specifier. Woven cane-like embedments with a
natural look include Coco Reed, Rattan, and Kane. Honeycomb and
Black Lace are knitted fabric embedments with a contemporary
Embedment of special papers printed with graphics seals the
graphics into the panel. Once cast into fiberglass, the sign,
display or decorative panel exhibits superior toughness,
durability and vandal-resistance. Common applications for
graphic embedments include industrial and safety signage,
transit sign panels, and interpretive panels for parks, zoos and
Diamond Design (DD3448) is the designation
given to an embedment panel incorporating 3/4"x 1-1/2" expanded
aluminum mesh, resulting in a panel with toughness, rigidity and
resistance to penetration. At the same time, the diamond-shaped
openings form an attractive pattern that allows generous passage

be imparted to the Crystal II variety in any thickness.
Maintenance of LUMAsite®
Most varieties of LUMAsite® sheets,
including Frost-SOS, are acrylic panels reinforced with
glass fibers that are cast into the panels during
manufacture. Some varieties have a micro-grain gloss
finish on both sides. Other varieties have a micro-grain
gloss finish on one side, and a cast-in satin finish on
the other (these varieties are denoted by an SOS
Protect the surfaces during fabrication. Sheets up to
.125" thickness are readily cut using a power-shear
capable of cutting 10 gauge mild steel. Saw-cutting is
readily accomplished using abrasive blades of the kind
used to cut masonry. Use a relatively slow feed rate.
(Although carbide-toothed circular blades can be used
for small cutting jobs, the blade will dull quickly and
Use a high-speed twist drill (or hole saw for larger
holes) to drill LUMAsite® sheets. Clamp the sheet to a
firm backing for drilling. Use water if necessary to
cool the drill (dip the drill tip into a cup of water).
Wear eye protection when using power tools. Wear a dust
mask if necessary to avoid breathing the saw dust. Refer
to the MSDS for other important safety information.
LUMAsite® sheets are ordinarily installed by
mechanically fastening them in place.
Pre-drill slightly oversize holes for fasteners. Use
metal fasteners, with bonded (metal/rubber) washers to
fasten panels in place. In vertical applications, hang
the panel first (install fasteners adjacent to the top
edge, but no closer than ½" from the edge) such that the
panel is not resting on the bottom edge. Then install
remaining fasteners working from top to bottom. Most
sealants, including silicone varieties, work
satisfactorily. For outdoor applications, acrylic foam
tape is recommended under joints and fastener lines.
LUMAsite® sheets are often used (usually in .090" or
.125" thickness) as lighting diffuser panels, installed
in a T-bar grid. Refer to the Lighting Specification
page, which includes guidelines for panel sizes and
Maintenance of LUMAsite® sheets after installation
primarily involves cleaning the surfaces of the
material. Most dirt and soiling are readily removed
using a non-abrasive soap and water applied with a
sponge or soft brush, then rinsing. Do not use abrasive
soaps or polishes. Note that using abrasive cleaners on
the surface can change the reflectivity (making a shiny
spot on the satin surface, for example), and can
otherwise scratch the surfaces.
Note that LUMAsite® sheets are acrylic-based materials,
and some solvents will damage the surface. Do not use
chlorinated solvents, paint removers, lacquer thinner,
acetone or methyl ethyl ketone. To remove marker, crayon
and some paints from LUMAsite® sheets, rubbing alcohol
or mineral spirits can be used (with adequate
ventilation and awareness of flammability). “Soft Scrub”
cleaner can also be used on LUMAsite® sheets.
LUMAsite® sheets are combustible. Fire
precautions similar to those appropriate for wood-based products
should be observed.
Fiberglass-reinforced acrylic classifies as a CC 2 material,
which means that it exhibits a burning rate of less than
2-1/2-inches per minute when tested by the ASTM D-635 method.
Some reinforced acrylic varieties of LUMAsite® sheets, include
Frost-SOS and White 1000-SOS, are available in a type FR
(fire-retardant) that classifies as a CC 1 material in .090" and
thicker gauges, which means that the material stops burning when
tested by the ASTM D-635 method.
Type FR panels also fall into a Class C category (NFPA 255) in
some thicknesses, which means that they exhibit flamespread and
smoke density values within specific ranges when tested by the
ASTM E-84 method. Additional information regarding burning
characteristics can be supplied upon request.
Note that no fire-retardant version of the Crystal II or
embedment varieties is available.
