Anyone have a preference between roxul rockboard and safe n sound? The Rockboard is a bit more expensive but looks like it would a bit easier to handle (no crumbling).

Also, I saw on youtube where a guy had incorporated airspace within the frame itself by putting in (what he called) wooden "cleats" to hold the Rockboard away from the wall.. What you ended up with is an enclosed airspace behind the material. Any opinions on whether this would be as effective as simply spacing your material away from the wall and leaving it open? Or, would that make any difference?

It seemed like a rather elegant solution to the whole "airspace: issue.

Just trying to measure twice....and cut once.

Thanks.

I recently moved my studio from one room to another. All my existing treatment was OC703 in frames (either 2x4 batts, or "superchunks" for the corners). Each of the individual batts were framed by 4x1 planking, effectively using a 2" air-gap behind a 2" thickness of OC703. These stiffer panes were easy to work with. I covered the framed batts with burlap.

In the new room, I used all the existing OC703, but I had a 4x4 walk-in which I decided to make into a recording area (not a booth, it's open-backed). For this I framed it out with 2x4 spacers, and then mounted a second frame over that. I then used safe'n'sound for my main insulation in this area between the studs... effectively giving an air-gap behind the insulation. The safe'n'sound is certainly floppier and more difficult to work with... but I bought 16" batts, and set my studs tight so that the safe'n'sound wedged in nicely and is self-supporting.

I used Bonded Logic's denim insulation both in the walls and in the panels and cloud, It's such an enclosed space, and I'm in there 8 hours a day, that I was unwilling to risk my health breathing in the nasty fumes from the Roxul.

And very very pleased with the result.

+1 on the recycled denim! no off-gassing of any kind. i hung mine with a french cleat plus a spacer of the same thickness at the bottom so i have a 1" stand off from the wall.

I think the denim stuff was $63 for 73 sf in my market (St Louis).
Roxul Safe n Sound is $47 for 59 sf.
YMMV

If I can find the denim stuff locally (didn't see it on my recent visits to either the orange or blue Borg), I'll use that. Otherwise, I'm going with the Safe 'n Sound batts.

It's in unfaced batts like fiberglass or rockwool insulation. 3 1/2" thick by 16" wide.

I found mine at Menard's, which is in the upper Midwest. Orange and Blue both say they can order it.
