safe n sound rigid enough?

[nomadx]

Hey all-
I've received a lot of help from you all over the past week or so. This forum is awesome.

I've got a question about the roxul safe n sound 2'x4'x3" panels. I want to use minimal wood for some absorption panels. Is the SnS rigid enough for a single 1"x2" wood frame on the back of (2) 3" panels wrapped in fabric (no wood on the sides)? I'm sure it would be fine in the beginning, but what about long term?

Thanks, all.

Bueller? Fry?

I never heard of the stuff before, but note that it is not 2' wide - only 16" (at least the stuff listed at Home Depot is).

Wow I dunno how you found it in 3" depth, I believe the preferred depth for low end freqs is 4" (but I'm sure someone will chime in, I plan on double layering 2")... I wouldn't only frame the back, when framed on the sides and bottom the SNS will stand no problem. SNS is NOT rigid enough to stand on it's own. Holding the Roxul to the back of the frame using the pressure from the fabric is going to compress the insulation and may compromise it's effectiveness. You are going to use the same amount of wood framing the sides or back, so why not do it the way everyone knows works...

I figured the 3" was not quite thick enough which is why I'm doubling to 6". Thanks for the info on rigidity.

Yeah, the price is more than what I've heard it's been purchased for in the past. Oh well; such is life! It's the cheapest I could find.
