OSI GreenSeries SC-175 Thermal and Acoustic Sealant is a non-flammable, latex-based sealant specifically designed to reduce sound transmissions and thermal drafts in all types of wall systems where sound-rated assembly is required. SC-175 acoustic sealant is paintable, remains flexible, and adheres firmly to wood, metal studs, concrete, drywall and most other building materials. Despite this, it still achieves and maintains its specific STC (Sound Transmission Class) values and meets LEED® requirements.
This sealant was developed primarily for commercial construction utilizing lightweight cavity walls and floor systems. Furthermore, it’s often used in office buildings, hotels, apartment complexes. In addition, it’s used in commercial and residential construction. SC-175 acoustic sealant is useful for exposed and unexposed applications at perimeter joints, floor and ceiling runners, cutouts in gypsum board, veneer plaster systems, and other areas where a sound rated assembly is required. This acoustic sealant can also be applied or buttered around electrical boxes and outlets, cold air returns, heating and air conditioning ducts, and other equipment penetrating wall surfaces for increased acoustic performance. It also works well for sealing sill and base plates in residential construction.
