Workshop Soundproofing
« on: February 26, 2001, 06:49:34 PM »
I am interested in soundproofing my workshop that is located in a garage below an upstairs apartment.  The ceiling is 2x10 joists and the walls are 2x6.  I have installed homasote over the 3/4 plywood sub-floor in the bedrooms. These rooms will be carpeted but the rest of the apartment is ceramic tile and Durock or 3/4 oak flooring.
Since I am ready to install insulation in the floor joists now, I am considering different consturction techniques.  I was told to use resilient channels with two layers of 5/8" drywall properly isolated with silcone calk at the corners.  The same for the walls.  How effective will this be at quieting my tablesaw humm?
Are there more effective construction techniques?
I purchased "EPA Soundproofing Book & Samples" from this website.  Now just looking for some more information.
Would it be possible to use rolled roofing material in anyway?

So far so good.  You should consider using foam mat inside the ceiling joists and a couple of layers of the "Loaded Vinyl" as a barrier.  Rolled roofing has been reported to give off an odor, but if you unrolled it and left it in the sun for a couple of weeks, and it was not exposed in the ceiling but covered, it might work OK.
