Product Overview

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.

Answer: 
I don't think acoustic calk is covered in any way by HIPAA as it has nothing to do with protecting the privacy of personal health information.

Rated 4.7 out of 5 by 3 reviewers.
Rated 5.0 out of 5.0 by Great Product I used 4 cases building a home recording studio. This caulk flows well, (unless old or stored improperly) , doesn't shrink excessively, and cures to an airtight/soundtight seal. I'm very happy with the results. October 4, 2016
Rated 5.0 out of 5.0 by OSI SC-175 acoustic sealant for recording studio This is an important piece of our soundproofing efforts to build a REAL recording studio. It is highly recommended by studio builders all over the world on the internet forum. February 18, 2015
Rated 4.0 out of 5.0 by 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. December 9, 2014
