ArtPerf™ Metal Clouds are typically found in noisy environments such as pump rooms, swimming pools, gymnasiums, and industrial fabrication work areas, but have clean architectural looks making them suitable in offices and conference rooms. These panels are fabricated with a galvanized solid steel outer skin and channel frame filled with mineral-glass fiber acoustic fill and are protected by an inner skin which consists galvanized perforated steel sheet that allows sound waves to enter the acoustic fill where they are turned to energy.
