AcoustAL™ - the aluminum panel
Bridges that support noise barriers require a low weight system. AcoustAL is a perforated aluminum panel system made for this application. Its name is derived from the root word Faddis uses for its acoustical barriers and the symbol for the metal aluminum. AcoustAL has also been installed for industrial noise control around electric transformers, chillers and diesel power generator stations. Panels can span 8 to 10 feet between posts for structure mounting or 12 feet for ground mounting. Panel weight is 3.5 pounds per square foot. Sound absorption is NRC 1.0, measured per ASTM C 423. Standard panel is STC 30 per ASTM E 90 and E413. Powder coating provides a durable surface color and a wide selection of colors. AcoustAL is suitable for exterior use as a surface mounted sound absorber for existing walls. It may aslo be used for interior applications on walls or ceilings, especially where a durable material, not subject to corrosion is needed, e.g., swimming pools and waste or water treatment facilities.
AcoustAL absorber panels can be fixed to existing walls to eliminate reflections using Tapcon anchors.
