A lower data hall acoustic ceiling tile system terminates at an owner-provided racking system. A two-inch perimeter angle is installed at the racking face, with sealant applied at the interface. A twenty-gauge sheet metal flashing is attached to the face of the racking framing and continues over the top of the hot aisle containment system. The acoustic ceiling system is supported by wire hangers as required, with intermediate supports spanning from the racking support structure. The hot aisle containment system is coordinated per mechanical drawings.
