THE STUDIO: Part Two-C: DURING CONSTRUCTION

Here is the installation of some different insulations used in the room. Additionally, I blew around 20 inches of fluffy insulation into the attic of the middle room, using a Lowe's rental unit. Also, note the putty formed around each electric fixture in both rooms. This product is supposed to be

for fire prevention and to stop sound from entering/escaping to room. Also not shown is the radient barrier (foam and foil insulation) I first added to the rehearsal room's walls and ceiling. I highly recommend a radient barrier for EVERY room construction job, new or rehab! I could immediately tell a difference in the room's temperature swings just with the addition of radient barrier.
All in all, the walls now have seven layers on them: (from outside going in) Vinyl siding, plywood sheathing, radient barrier, foam or fiberglass, mass loaded vinyl, and 3/4 inch sheetrock. Wish I had added another layer of sheetrock with "GreenGlue" between sheets to absorb more sound vibrations. Adding weight (mass) is the cheapest way to soundproof, and sheetrock is not expensive, just labor intensive.
