Specified Technologies SNS120W SpecSeal Smoke 'N' Sound Smoke and Acoustical Sealant, 20 oz Sausage, White

Protect smoke-rated walls and improve acoustic performance in security and surveillance installations with Specified Technologies SpecSeal Smoke 'N' Sound Sealant. This detector accessories sealant is an acrylic latex, water-based product designed to seal through-penetrations—pipes, conduits, cables, busways, outlet boxes and detector bases—while delivering measurable sound attenuation and smoke containment. Packaged in a 20 oz sausage (SNS120W), the sealant offers high-build, trowelable performance on vertical or overhead surfaces and can be applied with standard bulk-loading or cartridge methods for fast on-site work.

SpecSeal Smoke 'N' Sound is acoustically tested and UL GreenGuard Gold certified, helping you meet performance and environmental goals for monitoring rooms, network closets, and other sensitive areas. The white, non-toxic formulation remains flexible and water-resistant when dry, reducing rework and cleanup while accommodating minimal joint movement. Use this sealant to maintain fire integrity around detector accessories and cable penetrations, minimize noise transfer in control rooms, and protect surveillance and IT systems.
