Metal ceilings can either be used to reflect or absorb sound. Those designed to absorb sound have perforations allowing sound waves to pass through. Typically, an acoustical material is adhered to the back of these panels that helps increase the noise reduction coefficient. Metal ceilings are commonly made from aluminum, anodized aluminum, stainless steel, or galvanized steel. Many options for coatings and finishes are available. Commonly an electrostatically applied powder coating is specified. Powder coatings can be based on polyester, epoxy, or polyester-epoxy hybrid chemistries. This Common Product describes a 0.032” thick, 4’ x 4’ perforated ceiling tile based on aluminum alloy 3003, specified under ASTM B209/B209M. The tile described here is also coated with a polyester powder coat, and is backed with an acoustic nonwoven fabric composed of glass fibers and cellulose. For information on alternative coatings and backings see the All Contents tab. Panels may also be painted, laminated with vinyl or PVC-free laminate, or have a wood veneer applied. Fluoropolymer coatings, including those made from PVDF or FEVE, and antimicrobial powder coatings are also available. These additional materials and coatings were beyond the scope of this research, and will add additional hazards not considered by this Common Product.
