GREENCHOICE ACOUSTICAL SMOKE & SOUND SEALANT

Titebond GREENchoice Professional Acoustical Smoke & Sound Sealant is a non-flammable, latex-based product designed specifically for the reduction of sound transmission in wall partition systems. Its primary function is to achieve and maintain the specific STC (Sound Transmission Class) value of the system designed. GREENchoice Acoustical Smoke & Sound Sealant remains permanently flexible and adheres firmly to wood or metal studs, concrete, gypsum board, and most other types of building substrates. Its unique formulation is non-staining and non-migrating. The sealant is used for unexposed applications at perimeter joints, floor and ceiling runners (either wood or metal), cutouts in gypsum board, veneer plaster systems, and other areas where a sound rated assembly is required.

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.
