   Plastic Louver Technical Data

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

Specular Finish
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 brightness louver.

Durabolic Finish
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.
