Ceilings Substrate Coffer Description Decoustics Coffer acoustical ceiling panels are flat panels designed for use in waffle slab construction where good acoustical absorption is required. The back of the panels are typically positioned 2-1/4" (57 mm) down from the top of the recess in the waffle (coffer). A floating panel effect is achieved via a minimum 1" (25 mm) wide reveal which is required around each panel to facilitate installation. 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 and hardware which permits 100% accessibility. Finish Panel Concealed Alluminum Edge (Resin Optional) Mounting J-clip Standards, Tests and Approvals Panels 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 were tested with 3/16" (5 mm) clip mounting. All Decoustics panels are custom fabricated and offered in a variety of types, sizes, geometric shapes, thicknesses and finishes. Panels are currently available flat only.

Limitations A minimum space of 2-1/4" (57 mm) is required behind the panel for hardware and installation. Design Considerations 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 Maintenance Mechanically mount only by first installing Decoustics supplied clips to the inside of the waffle recesses (coffers) using the template and printed instructions provided. Installer to supply all anchors, substrate hardware and fasteners. In field, attach panel clips to panel backs, again using the template provided. Only handle panels wearing clean, lightweight, white gloves during installation. Install panels by connecting panel clips to coffer clips on one side and gently swinging the panel upwards to engage all four clips. Follow manufacturer's instructions for field cutting of panels. Refer to appropriate Decoustics “Cleaning and Maintenance Instructions” for any specific finish. If it is necessary to access coffer or plenum spaces, remove panels by lifting straight up to disengage clips, slide panel sideways 3/4" (19 mm) and then lower the panel.
