mat. Keep in mind that the American Mat is used to line the cavities only, not to fill the cavity. If thermal insulation is needed, use products such as rock wool, mineral wool, cut wool fibers, or my favorite, Roxul. Roxul is a great thermal rock wool based batt type insulation that has great soundproofing qualities. If thermal insulation is a requirement for the practice room or studio, then Roxul is the way to go.

Now we come to a crossroads, it is time to determine if decoupling the walls using resilient channels or American Sound clips is a necessity. De coupling is used when impact transmission or low frequency noise is a factor. Impact would come primarily from the drums (acoustic type) or the bass amplifier. However, if the band is using Marshall high powered amps (50 watt amps with 4 X 12 cabinets for example) along with miked acoustic drums and an Ampeg bass system, then decoupling will most likely be necessary. These methods and procedures will be explained in later articles. If decoupling were determined to be unnecessary, then the next step would be to find a good barrier material such as American mass loaded vinyl (which is a high grade mass loaded vinyl barrier). This barrier could be stapled directly to the studwork on a wall assembly or directly to the joists. This is a method that is used if cost or space constraints are factors. If the barrier material is to be stapled directly to the stud or joist framing then it is best that the seams be over lapped, caulked (using OSI acoustical caulking compound) and then taped with either a lead tape or a heavy-duty PVC seam tape. Once the Mass Loaded vinyl (MLV) is installed and sealed, it is time to install the final layer of drywall. I always recommend using 5/8" drywall as the final layer because of its mass and its sound blocking abilities. . It is always advisable to butter the edges of the last layer of drywall with acoustical caulk. You want to grab every STC (sound transmission class) point you can when trying to make your new studio as soundproof as possible. Finally you will tape mud and paint your final layer of drywall. Now you have a great soundproof home recording studio. We will discuss acoustical treatments for your studio in subsequent articles, but for now you are well on your way to having a professional grade-recording studio in your home.
