I'm building six 8'x4' movable walls to use in my studio as both gobo's, and to create a mix environment when needed around my mix station. We are using 8'x4' drywall (5/8"), studed at 24" (right down the middle) and I will be using 2'x4' sheets of insulation of one of the following:
Roxul Rockboard 60 ATS Acoustics Rigid Fiberglass Board
There will be 2" spacers in between the dry wall and the insulation, and the other side will be covered with burlap fabric right over the insulation for absorption. Which of the above would be better and why? I would like to go with the cheaper, but will go with the more expensive if necessary.
Thanks
