Product Overview

  • Reduces sound transmissions and drafts in wall and floor systems
  • Ideal for a wide range of commercial construction uses
  • Safe, non-toxic and eco-friendly with minimal odor
The OSI GreenSeries SC-175 Draft and Acoustical Sound Sealant is a non-flammable, latex-based sealant specially designed to reduce sound transmissions and drafts in all types of wall systems where sound-rated assembly is required. GreenSeries SC-175 is paintable, remains flexible and adheres firmly to wood, metal studs, concrete, drywall and most other building materials, while achieving and maintaining the specific STC (Sound Transmission Class) values and meeting LEED requirements. This sealant was developed primarily for commercial construction utilizing lightweight cavity walls and floor systems, ideal for use in office buildings, hotels, apartment complexes and other types of commercial and residential construction. Use it 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. It can also be applied or buttered around all electrical boxes and outlets, cold air returns, heating and air conditioning ducts and other equipment penetrating wall surfaces for increased acoustical performance. In addition, it works well for sealing sill and base plates in residential construction.

Can this caulk be used as a sound barrier between two layers of drywall to soundproof a room? How effective would it be for that purpose? Is the STC rating available? Thanks!

This product is not for use with plastic. You need SC-170 which Home depot is not currently selling. At this time Home depot has no appropriate product.

In the case of an interior wall, does this need to be applied on studs prior to the installation of drywall in order to be effective, or can one install this along the seam/corner where the drywall meets the studs after the drywall is already installed (i.e. from the other side of the wall before the other side's drywall is installed)?
Asked by: dreedw
The OSI SC175 Draft & Acoustical Sound Sealant is not meant to be applied to a stud and should not be used in the manner described. This product is not an adhesive. This product is used for sound control in wall partition systems or for air sealing where drafts may occur. The sealant is used 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. Sealant can also be 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. Works well for sealing the sill and base plates in residential construction for air sealing and draft control. More information regarding this product can be found on the Technical Data Sheet available at: www.ositough.com. For proper use of acoustical sealant in the construction industry you may wish to consult ASTM C 919 - Standard Practice for Use of Sealants in Acoustical Applications if you are a contractor. If you need further assistance, please call our technical team at 800-624-7767 so we can help. Thank you!

SC-175 28 fl. oz. White Draft and Acoustical Sound Sealant (12-Pack) is rated 3.7 out of 5 by 14.

The contractor and his workers actually preferred it that way, though, even though it takes more effort to apply via the the caulking gun. We also tried a different one that was softer, but that tended to “run” before it set.

I purchased this product to use as a sealant under plywood sheathing on new construction. It was reasonably easy to apply, although I suspect it would require a lot of effort if you tried to apply when cold. It is still pliable a week later but I have no idea how it age. Clean up was very easy with just soap and water. I purchased a case of this and two tubes arrived damaged. Home Depot customer service was great, I got a refund for the two damaged tubes.

Rated 4 out of 5 by from Compared to Tremco Acoustical Sealant... Building a super airtight energy efficient home (ie. passive house) requires a lot of sealing. Tremco acoustical sealant is the tube of choice because it stays gooey forever. That's a good thing for sealing, but it's black and MESSY. It also costs a LOT. So I bought this stuff to test as an alternative. QUALITY IS 3.5 Stars, not 4 based on below. Value is high. EASE OF USE: *** First off, use the tubes warm. Don't let them harden up in cold weather or you're muscles will give out in a half hour. Otherwise the product comes out of the tubes fine. And it sets up so it won't ruin your clothes, car, and everything else it touches. FLEXIBILITY: *** Can't really see how this works over long haul, but coming out the gate, I'd avoid it for sealing top plates and bottom plates and will stick with tremco. However, I think this is a way good alt for using in enclosed space like inside and inside the wall cavity or to seal up sheathing. It sets up similar to silicone caulking. Maybe a little softer. But it's still more akin to normal caulking than Tremco product. GREENNESS: ***** Five stars if it actually is green. The Tremco stuff is pretty toxic (I mean, relatively anyhow. The stuff we use to clean sinks and toilets is worse.) COST: ***** Cheapest thing out there.
