Pro-Series SC175 Acoustical Sound Sealant
is a one-part, nonflammable, latex base
acoustical caulk
designed specially for the reduction of sound
transmission in all types of wall partition
systems. Its primary function is to achieve and
maintain the specific STC (Sound Transmission
Class) value of the system designed.
This sealant remains
permanently flexible and adheres firmly to wood
or metal studs, concrete, gypsum board and most
other types of building substrates. SC-175 maintains a
tough rubber-like seal against air-borne sound,
air infiltration and moisture. SC-175™ offers
fast, smooth, easy application without
difficulty in extrusion. Clean up is also quick
and easy with just soap and water. Field tested
and field proven, Pro- Series® SC-175™ is
recognized across the country by drywall
manufacturers and architects as an effective
means of reducing sound transmission.
Pro-Series®
SC-175™ was developed primarily for commercial
construction utilizing light weight cavity walls
and floor systems. The sealant is used for
exposed and 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. The sealant is also
applied or buttered around all electrical boxes
and outlets, cold air returns, heating and air
conditioning ducts, and other utility equipment
penetrating wall surfaces for increased
acoustical performance. The product is also
excellent for perimeter sealing in residential
construction around base and sill plates to help
reduce air infiltration and unwanted moisture.
SC-175™ is used successfully in office
buildings, sound and recordings studios, hospitals, hotels,
motels, schools, apartment complexes and other
types of commercial and residential construction
where sound ratings are required.
