Here is the way out of the whole three leaf waste construction. The reasons the 2 X 4's are being used horizontally is to allow a lap area for the metal. Rather than 2 x 4 instruct your builders to sheath the building with OSB. This will solve the issue of how to mass it up on the interior of this wall(makes it easier) All the metal will lap properly so as to look and be correctly installed. Then maybe you can move forward and save a few dollars on the way.Hello Stuart. Thanks for your response.I wasn't referring to Brien's drawing. I was referring to my drawing which shows insulation and metal on the outside of the stud wall. Most all Pole Buildings of this type use this method of insulating the structure. I now understand the negative impact of this three leaf issue. But now I'm clueless on how to proceed. Brien's drawing does not depict the 2x4 side girt that the metal siding is fastened to. (as does mine, see photo). If I were to install the drywall between each stud, I would still have the 1.5" thickness of the side girt between the drywall and the metal/insulation. Should I replace the 2x4 side girt with two layers of 3/4" OSB or Plywood? I've read that using wood for my mass can cause resonance in the mid range.I'm not sure why you thought there would be insulation in there, between the drywall and the metal.My house is about 150 feet away from the upcoming studio, which will be used primarily for mixing. With the cramped space requirements, I planned on putting 2 layers of drywall on the interior wall and 1 layer of drywall on the exterior wall. I'm anxious to get your opinion on the double layer of OSB or Plywood on the exterior wall.One other point: depending on your target for isolation (ie, how many decibels do you need to stop), you might need more than one layer of drywall in there
