Substrate Ceilings Span Panel A Description Decoustics Span acoustical ceiling panels consist of a medium density core and an attractive range of finishes. The plenum or back side of panels is supplied complete with a clear vapor retarder. Typically employed in areas where a single span is desired. Span is available in up to 10'-0" (3050 mm) long panels and can provide up to 100% accessibility to plenum spaces depending on panel size. Panels are removed by lifting, tilting and lowering. Panel ends are supported at ceiling-wall junctions using exposed wall moldings or Tbar components. Panel joints are butted together, have defined joints or mounted to provide wide reveals. Panel B Crown molding (not by Decoustics) DPC-2 Panel clip T-bar — not required for spans under 48” to 60” (see Design Considerations) Panels A All Decoustics panels are custom fabricated and offered in a variety of types, sizes, geometric shapes, ellipses, vaults, acoustical domes, thicknesses, and finishes. T-bar DPC-3 clip DPC-2 clip B A Limitations Panel spans or sizes are limited to 120" x 60" (3050 mm x 1525 mm) for fabric finished panels, considering fabric width availability, 120" x 48" (3050 mm x 1220 mm) for vinyl finished panels, and 72" x 48" (1830 mm x 1220 mm) for coated finishes. Outboard edge of DPC-3 rests on edge of panel B B Design Considerations Standards, Tests and Approvals Surface Burning Characteristics (ASTM E-84): All panel components have a Flame Spread rating of less than 25. Note: Building code requirements may necessitate composite panel testing based on specified finish. A panel comprised of “Class A” (Flame Spread of 25 or less) components does not necessarily produce a composite panel meeting the “Class A” requirement. Decoustics has a considerable number of composite panel tests on file. Acoustical Data (ASTM C423: Type E400 Mounting as per ASTM E795).

Accessibility to plenum spaces above the ceiling is dependent on panel size, e.g. 100% accessibility is available for spans up to 48" (1220 mm) with chemically hardened edges, and 60" (1525 mm) for aluminum reinforced edges. For panel spans over these dimensions and up to 120" (3050 mm), accessibility is limited to approximately 50% of ceiling surface, e.g. every other panel. Consult with Decoustics for additional information. All lights, diffusers, speakers, smoke detectors, sprinklers, and similar items that penetrate or are located in the ceiling must be independently supported. The panels are not structurally capable of supporting the weight of any of these items. When using speakers in ceiling or wall panels, it is recommended the speaker grille be visibly mounted at the face of the panel. …cont’d
