SPECIFIED SNS105W SpecSeal Smoke ‘N’ Sound Acoustical Sealant

SpecSeal SNS105W is a high-quality acrylic latex sealant designed for sealing through-penetrations such as pipes, conduits, cabling, busways, and openings, as well as membrane penetrations like p-traps and outlet boxes in smoke-rated walls. This sealant is suitable for use in smoke control, noise control, and infectious/dust control applications where maintaining smoke barriers, sound attenuation, and air particulate containment is critical. It is compatible with a wide range of construction and penetrant materials, making it a reliable choice for electrical distributors and switchgear suppliers requiring effective sealing solutions.
