Aluminum edge Ceilings Panel Direct Mount 1/8” - 3/16” (3 mm - 5 mm ) Defined Joint To substrate non-accessible butt defined or reveal joints. Description Substrate Ceiling track Panel clip Panels Panel Butt Joint available with resin edge and specific fabrics only 1/8” - 3/16” (3 mm - 5 mm ) Defined Joint 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 F5 Mounting as per ASTM E795).

Panels are installed using a mechanical z-clip (slide and engage) method of fastening direct to a firm substrate such as gypsum board, concrete, steel deck, wood or similar surface. All Decoustics panels are custom fabricated and offered in a variety of types, sizes, geometric shapes, ellipses, vaults, acoustical domes, thicknesses and finishes. Standard thickness tolerance is ± 1/32” (1 mm). Limitations Essentially non-accessible. Progressive removal of panels is necessary. For curved applications (i.e. barrel vault), factory precurved channel is strongly recommended to ensure panel alignment. Design Considerations A perimeter reveal 1” (25 mm) wide is required around all ceiling areas to facilitate installation of the z-clips. Alternatively the reveal can be covered with an exposed, crown or cornice type moulding. All lights, diffusers, speakers, smoke detectors, sprinklers, and similar items that penetrate or are located in the ceiling must be independently supported. The panel is 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. Speaker function creates air movement and any fabric covering the speaker will experience premature soiling.

Mounting Methods Mechanically mount only, direct to substrate. Install panels flat and level to ± 1/16” (1.5 mm) over an 8’- 0” (2440 mm) length. Shim continuous ceiling track if necessary to obtain flat level ceiling. Install continuous ceiling track runners at starter, intermediate and finisher locations. Fit slide and engage zclips (mounted on back of panels) into ceiling track runners or onto adjacent panels, depending on panel type, size and layout. …cont’d

Ceilings Where possible, secure panels or mounting hardware to a substrate support such as metal furring or stud framing. Allow for 1” (25 mm) wide reveal around perimeter of each ceiling area. To prevent building vibration from dislocating panels, install locking pins, outboard clips or similar devices at perimeter locations. Refer to manufacturers shop drawings and installation instructions. Direct Mount To substrate non-accessible butt defined or reveal joints. Precautions Failure to install panels flat and level will void any warranty, and can result in over-stressing of panel clips and...
