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 A Mounting per ASTM E795).

MOUNTING METHODS
Mechanically mount only using either:
(a) For panels with spans to 60” (see Design Considerations) use lay-in method.
Panel spans opening and is supported on two edges using installer supplied moldings.
(b) For panels over 60” use installer supplied T-bar having a 15/16" (24 mm) face flange and 1-1/2" (38 mm) web height. Note: T-bar is first secured to factory installed DPC-2 clips mounted on panel backs and then the completed panel assembly is hung in place using wires or rods (see diagrams). Adjacent panels are supported either side of the primary assembly without hangers to allow easy accessibility to plenum spaces.

Note: The information provided in this Data Sheet is accurate to the best of our knowledge at the time of printing. However, we reserve the right to make changes when necessary without further notification. Suggested applications may need to be modified to conform with local building codes and conditions. We cannot accept responsibility for products that are not used, or installed, to our specifications.

Note: Only handle panels wearing clean, lightweight, white gloves during installation.Follow manufacturer's printed instructions for installation as well as field cutting of panels.
