Double frame, 1" drywall in between
« on: April 29, 2015, 05:19:09 PM »
Hey everyone,

I am building a soundproof room in be basement. All the walls are concrete except one.

The wall that needs soundproofing is already double framed. In between the frames there is 1" drywall.
The plan is to use safe n sound insulation on the inside of the room and outside. On the inside wall, add mass vinyl sheet, add ISO or genie clips, hat channels, 5/8 drywall.

Any other suggestions? Is having the 1" drywall in between the double frame a really bad thing? Not sure if I want to take it out since the wall is already built. Any advice ?

depending on if the cavities are or are not insulated and if your playing LF at High intensity would you lose some value with a triple leaf effect.
If the cavities are not insulated you might as well remove it to insulate and the build it out the way you are showing.
Use Isomax clips far better and use double drywall with green glue for best results.
