Parabolic louvers represent the most
sophisticated and optically precise
control media available. The advanced design concepts
and latest technology produce controlled lighting of
unparalleled visual comfort and
efficiency. The shape of the vertical cell
walls act as small reflectors, directing all light into
a task area.
A.L.P. plastic parabolic louvers are
available in polystyrene or acrylic, and come in depths
from 3/8" to 1" and cell sizes from 1/2" to 1-1/2".
These attractive louvers can also be used for accent or
perimeter lighting. 1' x 4', 2' x 2' and 2' x 4' sizes,
in finishes of specular silver, semi-specular silver,
and specular gold (Deco-Round 33 and 50, also in silver
and black finish). A protective durabolic finish is
recommended for all plastic specular silver.

Specification Finishes for
Plastic Parabolic Louvers
The mirror-like specular finish provided by A.L.P.
Lighting Components, Inc. provides the most precise
lighting and finish for brightness control. This rich
contemporary look enhances all ceilings in fixtures.
Reflectivity from the specular silver finish is never
less than 92%. Reflectivity from specular gold will be
slightly reduced. Metallizing done by A.L.P. continues
to set the standard in the industry.
Semi-Specular Silver Finish
A specially formulated translucent coating is applied to
the specular finish which reduces the high gloss level.
This results in omni directional diffused light giving a
warm halo effect around the louver and beyond the
cut-off angle. The semi-specular finish reduces the
contrast ratio between the ceiling and the low
A top surface coating used in plastic metallized
louvers, when the metallic appearance must be maintained
in a hostile environment. It is a durable finish that
protects the metallized louver surface from handling and
marring. The Durabolic finish withstands fingerprints,
smudges, dirt, and temperature changes. It is easily
cleaned with a soft cloth or mild detergent.
