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
The open-edge track gave the STC value of 29 through direct leakage
Single bead at the perimeter of
one base layer
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
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.

Surface Burning Characteristics for Building Materials
  -Tested as applied in two 1/4" diameter beads, 8 in. O.C.(Coverage: 2.8 percent of the exposed test sample area).
If using outside, do not apply if rain is expected within 12 hours. Not recommended for continuous submersion or use below the waterline. For best results, store above 40°F. Sealant should be dry to the touch and ready to paint in 2-4 hours. This product is freeze/thaw stable. For questions, please call our Help Line at 1-800-347-4583.
