STC RATINGS

Edge Detail STC Value Comments
Uncaulked 29 The open-edge track gave the STC value of 29 through direct leakage
Single bead at the perimeter of one base layer 49 This bead closed void but did not seal leakage around the joint between wallboard and track
Two beads, one under each base layer of gypsum board 53 The beads closed void and sealed leakage around track
Note: Taken from ASTM C919. The test partitions of metal studs 610 mm (24 in.) on center, with double layers of 13 mm (0.5 in.) wallboard screw-attached to each side. Sound attenuation blanket, 38 mm (1.5 in.), was placed in the void. The partition panels were erected, shimmed out 3mm (0.125 in.) at the periphery: top, bottom, and edges.
